Sandbox 91-94 Lower Marsh

A ruggedly handsome building sat on top of Flat Iron Square, with original parquet flooring, huge Crittall windows and bags of natural light. Floors of 1,200 sq ft take 30-plus people and can be reconfigured to your exact desk requirements, each with its own breakout area, kitchen and glass-fronted meeting rooms for 6-12. Take the lot and you get three workspace floors, a fourth-floor breakout with terrace, and a fully private entrance for up to 100 people.

A newly converted townhouse in the heart of London Bridge, designed with vibes in mind — huge sash windows and tall ceilings set off by earthy, calming colours and fun detailing. Small offices from 300 sq ft suit 6-10 people with loads of light; larger offices of 1,200 sq ft take up to 36, fitted with private lounge areas, glass-fronted meeting rooms, internal kitchens and phone booths. Meeting rooms across the building, from 4-person spaces to a large boardroom, are free for members.

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.

Dating back to 1891 as a paper-staining works, Battersea Business Centre now houses more than 140 companies under one expansive roof. Recently refurbished areas offer bright offices from around 90 to 900 sq ft alongside maker workshops, retail units and micro-warehousing, all connected by high-speed internet, CCTV and 24/7 access. The welcoming entrance foyer is staffed by the Centre Manager, with kitchenettes across the site and parking available — a rarity this close to Zone 2. Flexible licences allow you to upsize or tailor space as your operation evolves.

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.
