Conservation Strategy

INTRODUCTION

Background

The Crown Estate's vision for Regent Street recognises the importance of the architectural and historic heritage. It underpins the commercial success of the street as a shopping destination and a place to work. It is a major attraction for those who live and work or visit London.

This Conservation Plan is The Crown Estate's policy statement of how they propose to protect and enhance what is significant about Regent Street and its immediate environment. It is intended to provide guidance and direction to those undertaking works in the Regent Street area, ranging from major re-development to regular maintenance.

This Conservation Plan draws on the research into the history and heritage of Regent Street, recently published in the Regent Street Conservation Study - History and Conservation (2002).

The Conservation Study analyses and identifies what in the Regent Street area (see Figure 1) is architecturally, historically, culturally and socially significant (see the Summary of Significance in Appendix I). This document addresses what makes that significance vulnerable - what threatens or might threaten it - and puts forward policies that seek to counter vulnerability and protect the significant.

The Conservation Plan is also intended to complement, advise and support other policy documents being produced by The Crown Estate in connection with its proposals for modernising and refurbishing buildings along Regent Street, particularly the Architecture Policy. This document also addresses issues beyond the immediately planned works, although they are inevitably a major consideration and it is expected, therefore, that this document will be reviewed after five years and re-assessed.

In summary, this document intends to:

  • set out The Crown Estate's policy commitment to protect and enhance what is significant in Regent Street and its environs.
  • provide guidance to those planning changes or undertaking maintenance in Regent Street.
  • provide a basis for "in principle" agreements with the planning authority and others involved in the statutory planning process.
  • provide information and advice to all organisations active within the Regent Street area on The Crown Estate's policies on conservation.
  • support the Regent Street Vision by protecting and enhancing the significant heritage of the Regent Street area.

How the Document Works

The document is divided into three sections:

  • The Buildings - a description of what undermines or threatens the significance of the buildings, with policies that address these vulnerabilities.
  • The Context - a description of what undermines or threatens the significance of the setting and environment of the buildings, with policies that address these vulnerabilities.
  • Design Guidelines and Educational Materials - addressing issues of awareness and good practice.

Responsibilities

The study area, which includes Regent Street between Oxford Circus and Piccadilly Circus and its adjacent streets, is contained within the Regent Street, Soho or Mayfair Conservation Areas. All of the buildings in Regent Street are listed Grade II, excepting the Piccadilly Hotel, which is listed Grade II*.

The Crown Estate is the owner of all of the properties in Regent Street and parts of the side streets and back land areas. The buildings are leased either directly to individual tenants, occupiers or to head lessees, who sub-let to sub-tenants. The maintenance of the exteriors and common areas of the buildings is the responsibility of The Crown Estate (or head lessee), but tenants are responsible for their own internal finishes and fittings and shopfronts. The Crown Estate has only limited control of tenants' alterations, but they are subject to Listed Building and other statutory consents.

Other stakeholders include Westminster City Council, which as the traffic authority, is responsible for street paving, street and traffic signs, street furnishings and lighting, licensing street vendors, highways, traffic management and parking, street and highways maintenance and main agent. The Greater London Authority (Transport for London) is responsible for public transport facilities, including bus stops. The New West End Company is a partnership between the public, private and voluntary sectors involved in London's West End and is assisting in an increasing number of these areas.

THE BUILDINGS - VULNERABILITY AND POLICY

Pressures for Change

The Crown Estate's strategy is to ensure that Regent Street continues to compete as a major retail and office destination, a role that plays an important part in London's position as a world city. It is important therefore to match the quality and nature of accommodation to the needs and requirements of modern occupiers. Modern retail units tend to be larger and demand more spacious areas. Office tenants with international aspirations demand more than a scruffy common staircase, a 'coffin on a rope' lift and a view of a miserable glazed brick light well. Not only have space and environmental quality requirements increased, but also users now require and demand better heating/cooling and ventilation. In addition, there are an increasing number of regulatory requirements, which have a bearing on the accommodation to be provided (e.g. access for the disabled).

The joint pressures of planning and other regulations, changing commercial/tenant priorities and the need for modern facilities fundamentally affect the fabric of the buildings in Regent Street. They may require major works to achieve improvements and/or site acquisitions and demolition of Listed Building fabric and other un-listed built fabric in Conservation Areas. Even if the improvements do not require re-development, the requirement for better environmental conditioning increase demands for space to house plant. Occupiers will inevitably require changes to the built fabric, but will have to pay regard to conservation law policy.

Policy:
Proposals to modernise and improve the built fabric will be designed to the highest architectural standards and will be based on the Regent Street Architecture Policy and proposals will be informed by the Conservation Study - History and Conservation (2002).

The Regent Street Conservation Study concluded that the most significant elements of the Regent Street buildings were their principal elevations, including their associated attic and roof structures. Only a few buildings were designed as complete buildings with architectural pretension. Most have only scraps of significant internal fabric such as 19th century cellars, joinery elements etc. Therefore, an obvious design response to the need to provide modern accommodation and to preserve the significant fabric is to undertake re-development behind retained façades. This would not normally be considered good conservation practices. However, as the Conservation Study has shown, most of the Regent Street buildings were designed as "show façades" with little or no architectural pretension behind, it may be argued that mediocre early 20th century fabric might be replaced by better quality early 21st century fabric, if this will secure the future of what is truly significant.

However, where blocks were clearly designed with separate elements on significant elevations, homogeneous modern designs, which do not acknowledge their individual identity, may undermine their significance. It almost goes without saying that a new structure, which does not relate to the openings in retained fabric, will compromise its significance.

Policies:
Notwithstanding that the Regent Street buildings are listed, where it can be demonstrated that fabric is of poor quality and without architectural or historic interest they will be refurbished or re-developed to enhance both the public spaces (which will, in any event, be within a designated Conservation Area) and the tenant-occupied areas, providing modern accommodation with appropriate mechanical services with plant rooms discretely located.

Any proposal for re-development or refurbishment behind retained façades must respect significant fabric and ensure its long-term viability.

New structures will be designed to relate to the retained fabric and the design and sub-division of the interiors will respect and acknowledge any differentiation between retained elevations of separate buildings.

Regent Street and the surrounding streets are closely related in visual terms. The buildings of Regent Street provide contrast and interest to the side streets, while the side streets defer architecturally to the grand and gracious Regent Street. The balance of this visual relationship is quite delicate, as the ambience of the individual side streets affects Regent Street, particularly where there is a strong visual link.

Proposals for re-development raise questions of scale and context. The differences in scale between the buildings in Regent Street and those in other streets may be compromised by re-developments that do not take into consideration the sensitivity of that context. The side streets have a range of different scales of buildings, which could be undermined by insensitive and inappropriate increase in building mass.

Views in and around Regent Street and, particularly, the skyline views are significant. These could be affected by rooftop extensions.

Policies:
In the long term, buildings that are considered inappropriate to their location will be replaced and improvements made to generally enhance the study area.

To enhance the side streets, improvements will be made to the secondary elevations of the Regent Street buildings so, while retaining their own integrity, they make a positive contribution to the quality of adjacent areas.

Any re-development undertaken within the side streets will be carried out with regard to the scale and context of the existing fabric.

Proposals for alterations or redevelopment will retain and enhance the views both along and out of Regent Street.

Use

Regent Street and the surrounding streets are also related in terms of uses. Those who use Regent Street also rely on the services supplied in the side streets. It is fundamental to the survival of Regent Street that its key uses are viable and allow the street to function in ways, which ensure its ambience, and status is maintained. The loss of upper sales floors can be an issue where it affects the significant fabric.

To service the needs of shoppers, visitors and workers and to increase "dwell time" The Crown Estate aim to include more refreshment facilities in Regent Street. At present cafés, restaurants and bars are largely confined to the side streets, although department stores have such facilities. The location of large catering facilities at ground level could affect the ambience of Regent Street.

Policies:
Uses of the buildings will be restricted to those that support the significant fabric and ambience of the area.

In re-development and major refurbishment proposals, uses in side streets will compliment those in Regent Street.

Any major re-development or refurbishment in Regent Street will generally maintain retail uses at ground floor level, larger scale catering uses will be located outside these areas.

The Fabric

Although generally protected by legislation and/or the assiduous attentions of The Crown Estate and its agent's changes do occur to Regent Street buildings without permission. These acts can gradually degrade the buildings.

Controls are in place for such diverse matters as: flower boxes and planters; flag poles; security fittings; CCTV; entrances; pavements; roofscape (plant and air conditioning equipment); stone cleaning; external lighting; noise; hoardings and scaffolding; vacancy and agents' boards and illumination strategy. The pressures for, in particular, improved environmental conditions in the buildings, with associated ventilation plant and grilles, increased alarms and other security devices requires monitoring, as do Christmas light fittings.

The rear elevations of the buildings are not always as assiduously controlled as those that face onto Regent Street. Here the fabric is not generally as significant, but its contribution to the overall ambience of the area may be and should be taken into consideration when alterations are proposed. It should not be seen as an easy option for the location of plant, grilles and security devices.

Internally, again much of the fabric is protected by the Crown Estate agents and in the case of the Listed Buildings, by statutory controls. However, lack of maintenance, ignorance and the effect of alterations can lead to significant fabric being degraded and lost. This might particularly be the case with shop interiors, which might be perceived as ephemeral, or secondary areas such as basements and service areas.

Policies:
A maintenance plan shall be maintained for all of the significant fabric. Repair and maintenance programmes will be based on the Guidance Notes on Maintenance and Changes in the Appendix to this document.

A register of significant fabric shall be kept in the Gazetteer (see Regent Street Conservation Study).

Any alteration to significant fabric will be carried out in a manner sympathetic to the style of the building being altered. Any proposed alteration will only take place following due consideration of the full implications of the proposals on the significant fabric and shall as far as possible be reversible.

Any works to significant fabric shall be properly recorded, including recording of any fabric opened up during the works, and a précis included on the data sheet in the Gazetteer.

Locations of future M&E installations will be controlled.

Modern surface-fixed services will be removed from buildings when possible.

The Regent Street buildings' principal elevations are subject to close control. However, certain issues can undermine their integrity and diminish them. The elevations are all symmetrical above the ground floors, which have traditionally been fitted out by tenants. The individual blocks were designed to the Regent Street elevation as single buildings and piecemeal refurbishments and re-decorations can result in the eccentric decoration of windows, leading to an inappropriate patchwork. The introduction of modern windows and glass, such as tinted glass, are inappropriate to the most significant elevations. Window dressings too can introduce a haphazardness that may detract, particularly when obviously modern vertical blinds are employed. Gaudy and aggressive advertising at ground and first floors, also detract set out in the illumination strategy.

Policies:
Appropriate secondary glazing will be developed, which will be discrete when viewed from outside of the buildings.

Re-decoration of the principal street elevations shall be carried out on the basis that each elevation is an homogeneous whole.

Dressing of windows to rooms on the principal elevations will take into consideration the architectural importance and homogeneity of the group of buildings.

The floodlighting of any buildings in Regent Street will be carried out only to overall guidelines set out in the illumination strategy.

New shopfronts are closely controlled in Regent Street. However, in the side streets a wide and eclectic variety is present and should be encouraged. Poor quality inappropriate existing shopfronts undermine the quality of the street, but some modern fronts have their own integrity and add interest. Good original or later shopfronts are vulnerable when shop units are re-let or refurbishment is undertaken.

Policies:
Poor quality shopfronts on Regent Street will be replaced with new ones as and when tenancies change. These will be based on the Design Guidelines, but designers will be encouraged to interpret the guidelines and express some individuality.

New shop window displays will be subject to guidelines that ensure they are compatible with their location.

New shop fronts in the side streets will be designed to be appropriate to their location and to contrast with those in Regent Street.

Advertising and shop signs in the side streets will be appropriate to their location.

Suitable access for people with disabilities is now statutorily required by the Disability Discrimination Act 1995. Generally speaking, most entrances to buildings in Regent Street itself are level and shops and office blocks have lifts, although some of these would certainly not be suitable for wheelchair-bound people. To meet these requirements of legislation will affect the built fabric.

Policy:
A disability audit for the buildings will be commissioned and any conservation issues arising from recommendations will be addressed.

It is important that proposals to improve Regent Street and its environs occur in an orderly manner to ensure that certain parts of the street are not unnecessarily blighted by building works.

Policy:
To ensure that large-scale building works do not blight Regent Street at any one time, re-development and refurbishment will be undertaken in a phased manner and recognise the needs of the ongoing mix of uses.

Having set out the policies for the buildings, this document now turns to the spaces in between.

THE SETTING

Context

The character and appearance of buildings and the enjoyment of them is greatly affected by their setting. This section deals with the public realm and policies which influence the area as a whole.

Traffic and Traffic Management

The Vision for Regent Street aims to make the area a 'place for people'. Traffic has consistently been revealed to be the most consistent detractor to the ambience of the study area. The traffic in Regent Street poses a threat to pedestrian safety and creates a lower air quality which degrades the environment. Furthermore, the signage for pedestrians and the central crossing 'pens' are confusing, contradictory and even demeaning. There is a poor legibility for pedestrians and a walking strategy is needed to enhance the "quality of place". To appreciate the ambience and the quality of any built environment, it is necessary to be able to concentrate on it to a degree; this is not possible when it is dominated by motor traffic.

In addition to the immediate physical effect that motor vehicles have, the pollution, both audible and chemical emissions, affects the way that the buildings are used, increasing the need for both artificial ventilation (and the associated plant) and unsightly secondary glazing. Furthermore a plethora of traffic management signs and hardware litters the pavement and traffic islands, including barriers to corral pedestrians to particular crossing points, emphasising and helping to perpetuate a divide between the east and west sides of Regent Street which is also caused by the presence of the traffic itself.

Policy:
Traffic calming and reduction measures will be sought to improve the environment and enhance the ambience of the Regent Street area in accordance with The Crown Estate's transportation study.

On a street-by-street basis, the quality of the public elements affects the setting of the buildings in the study area:

  • Pavings in Regent Street are handsome, but the pavement lights, which constitute a large proportion of the pedestrian trafficked areas, are often rather scruffy and are an ad hoc mixture of materials.
  • Pavings in the side streets are almost invariably miserable and detract from the built fabric.
  • Current street furniture reflects the need to control traffic and pedestrians and is too dominant.
  • In Regent Street standards provide only atmospheric lighting, the street light fittings being attached to the buildings (with their associated cabling).
  • Street signs in Regent Street are of an inappropriate design and often ill-sited.

Although each of these points may seem rather minor, when added together they seriously undermine the quality of the setting of the built fabric.

Policies:
Street signs and furniture, including street lighting, will be reviewed.

Improvements to the road and pavement finishes in the side streets will be sought.

Pavement lights along Regent Street will be reviewed.

The Crown Estate is working towards making the needs of pedestrians dominate as part of a legible strategy.

Use

As mentioned previously, the side streets are important to the viability of Regent Street and they have a symbiotic relationship. However, the side streets often provide vehicular parking, as well as service access to the Regent Street buildings, particularly to the eastern side. These functions can overwhelm the side streets and undermine their character and ambience. The service areas generally throughout the study area depress the streets and make them vulnerable with accumulation of rubbish bins and seedy air.

Policy:
Service areas will be improved and will include storage of refuse off street as part of development proposals.

The study area is at the heart of the West End. Night-time users of the clubs and bars have similar bodily functions as everyone else (or possibly more so) and the side streets are a testament to this in the early morning. There are no 24-hour WCs in the Regent Street area - WCs are only available in the Underground station or in department stores (strictly for customers' use). Out of the hours that these are open, the side streets adjacent to Piccadilly Circus (in particular) appear to be utilised as a substitute, although the City Council have started to introduce 'pissoirs'. This basic public hygiene issue seriously diminishes the side streets. Intrusive street surveys do not encourage visitors to Regent Street and also need to be controlled.

Policy:
To enhance the ambience the provision and maintenance of 24-hour a day public lavatories at the southern end of Regent Street will be sought.

The nature of vending in Regent Street has always had a cache that is reflected in its overall ambience. This is undermined by licensed and un-licensed street traders selling gimcrack goods from tawdry stalls, which clutter the pavements and spoil views of, particularly, the Quadrant pavilions at Piccadilly Circus. The shoeshine man in Tennison Court and the winter time chestnut stalls may add to the charm of the street, being discreet, but hot dog and souvenir stalls do not.

Policy:
The removal from Regent Street of inappropriate street traders will be pursued.

Regent Street is one of the most highly trafficked thoroughfares in London. This level of use inevitably brings with it a general degradation through wear and tear of fabric. However, this is not generally a major problem and abuse, graffiti, fly posting etc is largely restricted to the side streets. However, maintenance of the 'public realm' is crucial to ensure that the gradual erosion by wear and tear does not undermine the quality of the streets.

Policy:
To enhance the environmental conditions, an improved street maintenance programme will be pursued.

This is clearly a policy, like many others in this section, on which The Crown Estate will wish to work closely with the City Council and the New West End Company to implement and its success will depend on the quality of the relationship between the two organisations.

Policy:
Having dealt with matters which indirectly effect the public at large the next section turns to aspects of awareness of the public as well as Regent Street's other stakeholders.

DESIGN GUIDELINES AND EDUCATIONAL MATERIALS

Promoting Awareness

Although the public perception of Regent Street is very positive, it is not always educated. Many of the tenants of the Regent Street buildings, , are aware of the historic nature of their buildings and are, by and large, proud of them and enjoy showing them off. The public at large, however, are perhaps less well advised and certainly are unlikely to be aware of the significant historic interiors within the less public buildings.

Policies:
To promote the findings of historical research including the Regent Street Conservation Study and its survey document.

To engender an interest and understanding of Regent Street origins and sponsor exhibitions from time to time, use of a website and a 'street trail'.

For new tenants, a briefing note will be produced on a building-by-building basis to alert them to the history and significance of the building and part of the building they occupy to help engender a sense of propriety.

The Crown Estate has recently published a pamphlet which briefly describes the history of Regent Street. The full research document has been put on the website www.regentstreetonline.com. It is hoped that this will help provide useful information for both the general public and the practitioner alike.

CONCLUSIONS

This set of policies designed to protect features of significance in conservation terms in Regent Street is the third stage in the preparation of The Crown Estate's Conservation Plan. It follows on from the research undertaken by Donald Insall & Partners on the history of the area and the practice's conservation assessment which identified the significant features of Regent Street. This document contains a set of policies which are designed to ensure that these features are protected and enhanced.

The policies relate to the buildings, spaces in between the buildings and the need for awareness of the stakeholders and the public generally.

The Crown Estate is aware that it cannot implement these policies on its own. It needs the help and support of a wide group of interested parties, including the regulatory authorities, the tenants of properties on the street, as well as the support of the public at large.

The Crown Estate also recognises that many of these policies may not be able to be immediately implemented. However, in recognition of the importance of this matter, it is proposed to continue an active dialogue with all relevant parties to support measures which will achieve the aims of these policies in the longer term.

Appendix I

What is Significant about Regent Street - A Summary

To summarise the assessment of significance, different aspects of the buildings and streets in the study area have been divided into sections, starting with the largest scale and the streets themselves and finishing with particular elements of the buildings.

Townscape, Building Groups, Character, Ambience

This is an assessment of the relative significance of the streets in the study area:

Rear elevation of Regent Street buildings to Blocks W8, W5, W4, W3, inappropriate shopfronts and alterations to Regent Street elevations, mismatched and poor quality pavement lights.

Appendix II

Guidance Notes on Maintenance and Changes to Significant Fabric

These notes are intended to advise those working on the fabric described as significant in the Gazetteer in the Regent Street Conservation Study.

Protecting Significant Fabric

Before any works are carried out to significant fabric, or to fittings or elements on or around such fabric, anything that might be susceptible to damage shall be properly protected.

Services in Significant Fabric

Generally

  • When installing new services preference should be given to locating them within existing voids and chases.
  • Routes for new services should be considered and designed with a view to preventing the further damage or destruction of historic fabric.
  • A record should be kept of all new services installations.
  • Where historical services or pieces of plant are to be replaced, consideration should be given either to leaving them in situ, or where this is not possible offering them to a relevant learned institution or collection for salvage.
  • During alterations to services where existing services, which are not designed to be seen, are visible examination of alternative locations should be undertaken to remove them from view.

Lighting

  • Cable routes should as far as possible always be within existing voids in the building.
  • When installing new light fittings, or lamps, items appropriate to the sensitivity of their location should be installed.
  • When installing new light fittings in historically or architecturally significant areas, consideration should be given to whether they might adversely affect the historic fabric either physically, due to the need for chases to allow for the installation, for example, or visually.
  • External lighting should be maintained as historically appropriate to the setting.

Heating

  • Pipe routes should, as far as possible, be kept within existing voids in the building.
  • Redundant fireplaces, grates, flues and chimneys should be maintained.

Ventilation

  • New ventilation plant should be located, as far as possible, in locations that are discrete.

Lightning

  • Lightning conductor tapes should be run, where possible, behind or adjacent to down pipes or other vertical features.
  • Stake pits should be located with consideration of the significance of the pavings.

Public Health/Rainwater Goods

  • When replacing visible above ground pipe work this should be done with consideration of the sensitivity of its location, and generally on a like-for-like basis, unless the existing fittings are already inappropriate.
  • Plastic fittings should not be used.
  • When replacing or installing new manhole or grating covers, the sensitivity of their location should be considered. Generally cast iron would be appropriate, or stone if the manhole does not require to be sealed and is internal. Pressed steel covers should be avoided.

Significant Floors

  • Floors generally should be replaced or repaired on a like-for-like basis, except where modern finishes have replaced earlier material or earlier material is inappropriately installed when consideration should be given to reinstating the earlier finish, or something appropriate to the setting of the room.

Significant Joinery

Generally

  • Joinery should be repaired rather than replaced.

Doors

  • Repairs to doors and frames and linings should be carried out with materials similar to those existing.
  • Doors and doorways are particularly vulnerable to damage when works are being undertaken and appropriate protective measures should be taken at these times.
  • Doors should be maintained in good working order and over opening avoided (use door stops if necessary).
  • External doors should be kept well decorated.

Other

  • Repairs to joinery should be on a like-for-like basis.
  • Moving joinery should be maintained in good working order.
  • External joinery should be kept well decorated.
  • Alteration of significant joinery should be avoided.

Windows

  • Windows and window furniture should be kept in good working order and well decorated.
  • Repairs to windows, frames, sills and linings should be in like-for-like materials.
  • Windows are vulnerable to damage when works are being carried out to external elevations, appropriate protective measures should be taken.

Significant Ironwork and Other Metalwork

  • External ferrous metalwork should be kept well decorated.
  • Metal windows and window furniture should be kept in good working order and well decorated.
  • Iron is subject to damage (wrought iron bends but cast iron breaks if subject to impact) so when works are being carried out adjacent to significant ironwork appropriate protective measures should be taken.
  • Only those with appropriate smithing skills shall undertake repairs to wrought ironwork and bronze work.
  • When repairing cast iron 'metalock' or welding techniques should be used rather than brazing.

Significant Glass

  • Replacement of historic glass should be avoided.
  • Glass should be protected when works are being undertaken in areas adjacent.
  • Replacement of damaged glass should be carried out on a like-for-like basis.

Significant Ironmongery and Door Furniture

  • Replacement of historic ironmongery should be avoided, repair where possible.
  • Overhead door closers on historic doors should be avoided, floor springs or closers in the rails or stiles are more discrete.
  • Replacement of historic locks and latches should be avoided, add mortice locks if extra security is required.
  • Addition of modern fittings such as escutcheons and locks to historic doors should be avoided. Modern mortice locks can be added with a keyhole thread.

Significant Decorations

  • In architecturally or historically significant areas research into previous colour schemes should be carried out before re-decorating.
  • Decoration of the external elevations should be co-ordinated.
  • Properly qualified conservators should be employed to carry out stripping of paint coatings in significant areas.

Significant Finishes

External

  • Replacement of or repairs to all external finishes: brick, stone, lead, slate etc, should be in like-for-like materials.
  • The external fabric should be maintained in weather-tight condition.
  • Historic fabric should be repaired rather than replaced.
  • Alterations to external fabric should be carried out using construction methods and materials similar to existing adjacent fabric.
  • Some external finishes are susceptible to damage when works are being carried out, proper protection should be in place before commencing operations.
  • External cleaning of brickwork and stonework should be undertaken only after full consideration of the implications for the homogeneity of the buildings as a group.

Internal

  • Alterations to, or replacement of, or repairs to significant historic internal finishes should be in like-for-like materials using similar techniques.
  • Historic plasterwork and stonework, particularly enriched work, is highly susceptible to damage when works are being carried out, proper protection should be in place before commencing operations.

Significant Fittings

  • An inventory of significant fittings and furnishings should be made and a record kept of their location.
  • Regular inspections of historic fittings and furnishings should be undertaken and a maintenance programme instigated.

Fire Safety and Implementation in Significant Fabric

  • Any implementation of fire safety requirements should be sensitive to the significance of the buildings and not undermine or de-value this significance.
  • Wherever possible the need to change to accommodate fire safety installations should be avoided by management of risk rather than alteration of the fabric.
  • When planning improvements to the fire safety of different elements or areas of the building alterations should be considered in the light of the particular significance of the element or area being addressed, and the affect of alterations on the historic and architecturally important fabric and settings assessed with regard to the requirements of the building area and building element policies.
  • Alterations to historic joinery, glass and ironmongery should be avoided. Use the English Heritage guidance notes on the upgrading of doors for fire purposes, and if alterations are the only solution, if possible make them reversible and use materials that reflect the existing fabric.
  • Emergency lighting should be installed, as discretely as possible and, in historic rooms, should be part of the permanently installed lighting scheme.
  • Standard fire escape signs, fire door and similar signs are inappropriate in historic interiors. These should be avoided. Suitable signs should be designed for these sensitive areas and developed with English Heritage for agreement with the local fire officer and the licensing authority.

Accessibility and Implementation in Significant Fabric

  • The Crown Estate is committed to accommodating the requirements and aspirations of people with disabilities and the imperatives of the different legislation. However, any implementation of access requirements should be sensitive to the significance of the buildings and not undermine or de-value this significance.
  • Wherever possible the need to change to accommodate access requirements should be avoided by management rather than alteration of the fabric.
  • When planning new access, alterations should be considered in the light of the particular significance of the element or area being addressed, and the affect of alterations on the historic and architecturally important fabric and settings addressed with regard to the requirements of the building area and building element policies.
  • Alterations to historic finishes and fabric should be avoided, but if they are the only possible solution, if possible, make them reversible and construct the alterations in materials and in a manner sympathetic to the existing fabric.

Security and Implementation in Significant Fabric

  • The installation of any security plant, grilles etc and alterations to the fabric to make the buildings more secure should be sensitive to the significance of the buildings and not undermine or de-value this significance.
  • Wherever possible the need to change to accommodate security requirements should be avoided by management of risk rather than alteration of the fabric.
  • When new security installations are being planned they should be considered in the light of the particular significance of the element or area being addressed and the affect of the alterations on the historic and architecturally important fabric and settings assessed with regard to the requirements of the building area and building element policies.
  • Alterations to historic finishes and fabric should be avoided but if they are the only possible solution, if possible, make them reversible.

Signage in Significant Fabric

  • When installing new signs they should be appropriate for their location and be sited in positions that do not compromise the architectural setting in which they are positioned.
  • Historically interesting signs and signwriting should be preserved. If covered over an appropriate note should be made on the relevant sheet in the Gazetteer.
  • Shop sign friezes should be repaired with sacrificial new stone inserted when existing stonework is heavily disfigured.
