Rx London Park Street, Mayfair

110 Park Street is a red-brick Victorian corner building in North Mayfair, on Park Street at its junction with North Row, reconstructed in 1990/91 behind its original facades to give roughly 28,000 sq ft of Grade A office accommodation across lower ground, ground and four upper floors. The freehold has been held by Ho Bee Land since August 2015. The building's own reception directory lists Silphium Asset Management, Rede Partners and Flexjet among the current occupiers — this is a conventionally multi-let office building, not a managed flex or coworking building.

Three upper floor plates are being marketed as direct lettings by RX London Limited (the sole leasing agent, not a flex operator): 4,921, 4,909 and 4,721 sq ft, all delivered as Cat A+ fitted space by Whitepaper (roughly 32 desks, five meeting rooms, an executive office, two phone booths and a lounge across the fit-out). Only the 4,921 sq ft floor is shown as genuinely available now, quoted at £167.50/sq ft/annum (£68,689 per month); the other two floors are on RX London's own site marked "Coming Soon" with rent on application, despite the sheet flagging all three as available now — see the flags below. All prices are monthly GBP.

Bond Street (Central, Jubilee and Elizabeth lines) and Marble Arch (Central line) are both a short walk away, with Oxford Circus and Green Park also within reach (times per the agent's own marketing, not independently timed — treat as approximate).
