Rx London Margaret Street, Oxford Circus

70 Margaret Street (recorded on Westminster's non-domestic EPC register as "DMA House") is a six-storey corner office building in Fitzrovia, W1W 8SS, at the junction of Margaret Street and Great Titchfield Street, a short walk from Oxford Circus. It has been recently refurbished to Cat A specification with a 1,000 sq ft roof terrace and new end-of-journey facilities (confirmed via RX London's own live listing and the non-domestic EPC register, which separately shows the whole building at 956 sq m / c.10,290 sq ft, EPC rating D valid to August 2031). The sheet names "Rx London" as operator, but RX London LLP (rx.london) is a West End property advisory and leasing agency marketing floors here on the landlord's behalf, not a flex/managed-office brand — no such brand runs this building, and the actual landlord/freeholder could not be identified from the sources checked (RX London's own page, the EPC register, Companies House and general web search all drew a blank; see missing[]).

2 private-office floors are available, both quoted by the sq ft with rent "On Application": the ground floor (1,819 sq ft) and the lower-ground floor (1,636 sq ft). Both are unfitted Cat A shell space (no partitions, furniture or desks fitted) — desk count is not published by any source. All prices, where quoted, are monthly GBP; no monthly or per-desk figure is published for either floor. RX London's own live floor table also lists four upper floors (1st–4th) in the same building as "Under Offer" — those are not part of this listing.

Oxford Circus (Central, Victoria and Bakerloo lines) is the nearest Underground station, a short walk north from Margaret Street (exact distance/time not sourced — verify); the wider Fitzrovia/West End retail and dining area is on the doorstep.
