Summer 2010 sees the London Festival of Architecture come to Regent Street.

The annual festival, a celebration of our capital city's finest architecture, is this year working closely with The Crown Estate, the Royal Parks and Westminster City Council, RIBA London to highlight the potential of an improved pedestrian route along the original John Nash plan of 1811.

The route will explore the origins of Nash’s vision, highlighting the historic features of existing buildings, at the same time as seeking to explain how the route could be enhanced today.

One way in which the LFA intend to do this, is through using visual markers on pavements and encouraging retail shops to engage in the route through window displays.

Anthropologie, COS, Oasis, Austin Reed and Banana Republic are all involved in the scheme, inviting designers to take creative licence with their windows for the duration of the festival.

At Banana Republic , Moxon Architects have collaborated with the store to creat what appears to be a visual game of hide and seek... Click here to see Regent Street TV clip

Down the street at Anthropologie, Sarah Wigglesworth has helped the brand to 're-imagine' a welcoming city, combining architecture, fashion and product in a world where buildings become garments, and duvets represent clouds... Click here to see Regent Street TV clip

COS and Spacelab (a RIBA award winning architectural practice) have experimented with depth, scale, perspective and methods of visual communication, creating alternating patterns to stimulate connections between architecture, fashion and the public. Click here to see Regent Street TV clip

Across the road, Austin Reed have joined forces with Tonkin Liu, hosting an installation from a team of international collaborators from Taiwan, Japan and England. Click here to see Regent Street TV clip

Oasis have teamed up with architects Hawkins/Brown, artist Bob and Roberta Smith and London beekeeper James Hamill to create their window installation - 'The Plight of the Humble Bee'. Click here to see Regent Street TV clip

And finally, after marvelling at the unique window displays, pop down to Lower Regent Street for the Sofitel St James Hotel.

Currently hosting 'Lost London' this is one exhibition that, similarly to the festival itself, celebrates all that is wonderful about the architecture and the history of our city.

Presenting a selection of historical photographs of a now vanished London, from the period of a horse-drawn city in the late Victorian age, to the devastated streets and buildings of the Second World War, this free exhibition has been re-staged for the LFA2010, and based on the best selling book, Lost London: 1870-1945.

Set to showcase some of the best images from the English Heritage archive of early London photographs (inherited from the former London County Council). marked for demolition, the collection of photographs is an example of stunning works of art in their own right – many of which go on display for the first time.
