The OWO Residences by Raffles

The corridors are three metres wide because messengers rode bicycles down them. The Old War Office was built in 1906 to William Young's design, worked in by Churchill, drawn on by Ian Fleming, and closed to the public for more than a century. The Hinduja Group restored it with the original mosaic floors, oak panelling and the layout largely intact — the building now does something else in the same shape.

Eighty-five residences from studios to six-bedroom penthouses, 86 to 359 square metres, ceilings to 4.4 metres, two of them in the turrets, with 30,000 square feet of residents-only amenity and a 125-key Raffles hotel in the same walls. EPR Architects; residence interiors by 1508 London; hotel interiors by Thierry Despont. Raffles operates both the hotel and the homes — agreed in two stages, June 2017 and February 2020 — which is rarer than it sounds and is the difference between a serviced building and a licensed one.

Two things the register carries rather than resolves. The co-developer is named as OHL Desarrollos in the 2020 announcements and as Onex Holding in later sales material, and the register does not assume they are the same party. And the opening was promised for early 2022: the hotel opened in 2023, residences were still selling into 2025. Three years is an ordinary slip on a Grade II* restoration and it is nowhere in the marketing.
