Gridiron Building

Built in 1889, 14 Old Queen Street is a discreet converted Victorian townhouse holding a handful of well proportioned private offices. It stands a short walk from St James's Park and the Palace of Westminster, and its roof terrace looks across to Methodist Central Hall, where the United Nations held its first meeting in 1947. The street itself is first recorded in 1547, on the south side of a royal deer park; the road just north of it was named Birdcage Walk after the aviaries Charles II kept there. Reception is staffed from 08:30 to 18:00, and the building is accessible 24 hours a day, 365 days a year.

Alliance House at 12 Caxton Street is the newest building in the Imoxis portfolio and is set to offer the most shared space of any of them. Past a traditional Art Deco entrance porch, a dual aspect reception and living room open into the building, and the lower ground floor is given over entirely to clients, with meeting rooms, breakout space, a large kitchen inside Alliance Hall, a gym and a music and podcast room. Completed in 1938 to a design by Murrell and Pigott for the British Temperance Movement, on the former site of the Westminster Medical School, it keeps its black Crittall windows, Portland stone entrances, terrazzo and pitch pine herringbone parquet floors, and the oak panelled Alliance Hall at its centre. Reception is staffed from 08:30 to 18:00, and the building is accessible 24 hours a day, 365 days a year.

A 10,000 sq ft repurposed textile factory on Argall Avenue with maker studios, creative studios and music studios for makers, designers and musicians, plus on-site parking.
