Baker Street, a joint venture development between Derwent London and The Portman Estate, is a major central London scheme providing a mix of uses in the heart of London’s West End.

The project occupies an entire urban block, flanked by Baker Street and Gloucester Place, and gave us the chance to design at a significant urban scale to enhance connectivity and access, revitalise street presence and maximise opportunities, creating an attractive new public realm. A public arcade beneath the centre of the office block leads to a new landscaped retail courtyard, and a route through the Georgian terrace on Gloucester Place.

The project features a 200,000 sqft office building, 42 residential apartments, 10 affordable housing units developed in conjunction with Native Land, and 20,000sqft of prime retail space. 

The development is a significant contribution to Derwent London’s high quality, ‘long-life, loose-fit portfolio’, and will be the first of its NABERS UK certified schemes, targeting energy-efficiency. The Net Zero Office building project is all-electric, with natural ventilation, and targets an ambitious range of industry benchmarks including a BREEAM excellent rating, Well ‘Enabled’, Wired Platinum, zero waste to landfill, and an EPA A rating. It uses Derwent London’s Smart enabled systems to monitor and regulate the building’s performance in use.

A highly contextual design will reference the surrounding streetscapes of Georgian terraces and mansion blocks. The project features an efficient post-tensioned RC structure on a 7.5m grid and a high quality palette of materials including Portland Stone, York Stone paving and hand-made bricks. Designed to appeal to the next generation of office occupiers, 25 Baker Street offers an elegant and contemporary scheme with lots of amenity, roof gardens and enhanced public realm.
