Langham Estate Eastcastle Street, Oxford Circus

50 Eastcastle Street is a red-brick, warehouse-style former industrial building on the historic site of the Princess Theatre, on the south side of Eastcastle Street at its junction with Winsley Street, in Fitzrovia/Noho, London W1 — one of the West End's media, design and tech quarters just off Oxford Street. The building has just been newly refurbished (completion Q2 2026) as part of The Langham Estate's wider £50 million investment across its Fitzrovia Quarter, and is owned and let directly by The Langham Estate, the Fitzrovia freeholder — not a flex/coworking brand.

Three CAT A office floors are available now, together totalling 45,627 sq ft: a 1st-floor floor of 13,135 sq ft (up to 146 workstations), a 2nd-floor floor of 24,204 sq ft (up to 269 workstations, one of the largest continuous floorplates in W1), and a 3rd-floor floor of 8,288 sq ft (up to 93 workstations). Prices are quoted monthly in GBP, exclusive of VAT. These are raw, unfurnished CAT A shell floors let directly by the freeholder rather than fitted/serviced private-office suites — a tenant would fit out the space themselves.

Transport is excellent: Oxford Circus (Bakerloo, Central, Victoria lines) is a 2-minute walk, Bond Street and Tottenham Court Road (both Central line, plus other lines) are about 7 minutes, Goodge Street is 10 minutes, and Great Portland Street is 13 minutes — per the operator's own journey planner.
