A close analysis of a key public route through the city, linking a series of public spaces, demonstrates a varied roofline formed by a number of types; the double mansard is prevalent. The composition of buildings enveloping Trafalgar Square is defined by both similarities and differences, no uniformity exists. The site has two contrasting edge conditions - Trafalgar Square, a public square characterised by energetic movement and events, and Spring Gardens, an intimately scaled street connecting to the monumental admiralty arch.
Layouts are to be responsive to the edge conditions of the site, locating living and entertaining space along Trafalgar Square and bedrooms along Spring Gardens. The double mansard roof form will be reinterpreted to define a new top to the building.
Existing facades of heritage value are preserved and enhanced, including the clock tower facing on to Trafalgar Square. Double aspect apartments maximise far reaching views of London’s cityscape. A new discrete layer to the building is provided, defining its roofline within the urban block and referencing roof forms scattered across the public route through the City. Copper sheets fold from the external roof form into the interior space, terminating through the formation of a stair within a double height central living space.
