10 New Burlington Street

London W1. 2013

  • Project Details
  • Completion: 2013
  • Cost: £46.5 Million
  • Clients: The Crown Estate

The first chapter of an evolving urban story, 10 New Burlington Street (W4) is a layered reinvention of an urban block in central London. A triple-glazed skin – gently curving inwards at top and bottom – emerges behind an ‘L’ of the retained corner façades of a substantial city block to define a new volume that connecting a collection of secret garden spaces, which remake the previously unused Burlington Mews. Within the new volume, six new floors and a core are inserted, centred by a five-storey atrium clad on one edge in scalloped blue faïence tiles that to soften light and surface. Below, forgotten, listed vaults are re-inhabited and put to new uses. Above, an exposed steel structure on the sixth floor resolves the curving geometry of the facade while opening up the building’s perimeter to expansive views and a rooftop terrace. In territory originally defined by Nash, W4 arranges 40,000 square feet of new retail space at basement, ground and part first floor below optimised office floorplates totalling 95,000 square feet across six floors. The project’s non-identical twin, also for the Crown Estate, sits across the road on the other side of New Burlington Street.

The Site

The site falls within the Regent Street Conservation Area, which is characterised by flagship brand clothing stores as well as international art galleries and tailoring around Savile Row.

Regent Street itself is a major shopping street and thoroughfare in London’s West End. Starting as Lower Regent Street at its intersection with Charles II Street and Waterloo Place, it runs north to Piccadilly Circus then becomes Regent Street by turning westward. It then continues past Oxford Circus becoming Upper Regent Street and ends at its intersection with Langham Place, Cavendish Place and Mortimer Street.

The Proposal

Initial Sketch


'The Tulip'


Left: 'The Tulip'- Stepped form: complex and apologetic. Coninuous taper: confident and elegant
Right: Tulip form reduces perceived massing and provides better sun penetration into public realm at ground



Engagement of Old and New

Left: Massing against historic fabric - new facade in no. 12 New Burlington Street slots in between re-built/remodelled flank walls
Right: Unifying variations in building heights and floor levels - stepping back of top floors create continuous roof terraces and minimise building mass at street level creating an atrium behind nos. 13 and 14 New Burlington Street.
