    A net zero office building with new landscaped public realm

     
    Location:London, United Kingdom
    Size:28,000 m²
    Client:Derwent London
    Year:2025

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

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

    The project features a 200,000 sq ft office building, 42 residential apartments, 10 affordable housing units developed in conjunction with Native Land, and 20,000sq of prime retail space. A public arcade beneath the centre of the office block will lead to a new landscaped courtyard, and a route out through the ‘Georgian’ terrace on Gloucester Place.


    The development will be 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 will be all-electric, with natural ventilation, and is targeting 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 will use 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 will feature 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 will offer an elegant and contemporary scheme with lots of amenity, roof gardens and enhanced public realm.

    Completion is expected in 2025.
