Overview
20-22 Mortimer Street is a Sub800 self-contained managed office building on one of Fitzrovia's best-known office streets, moments from Oxford Circus and the BBC's Broadcasting House. Sub800 takes the building's floors and lets them whole, so each business gets exclusive use of its own space with the operator running everything behind the scenes.
Space is available from a 3rd-floor suite for 17 desks up to the full building across lower ground, ground, 1st, 2nd and 3rd floors for 109 desks, all unfurnished and ready to fit out. The all-inclusive monthly price wraps up rent, service charge, buildings insurance, business rates and electricity in one figure, alongside weekly cleaning, a remote concierge service and essential kitchen items, so there are no separate bills to manage.
Oxford Circus (Central, Bakerloo and Victoria lines) is a 5-minute walk and Goodge Street (Northern line) is just as close, with Tottenham Court Road station roughly 8 minutes away for the Elizabeth line. The building sits within easy reach of Oxford Street's shops and Fitzrovia's dense cluster of independent restaurants, cafes and post-work bars.
