A tricked-out Nash townhouse directly overlooking Regent’s Park has been listed for sale at nearly £16mn. Weighing in at over 8,000 sq ft, the Regency affair on Prince Albert Road is described as a “rare gem”, and packs some “indulgent” features. A successful basement extension has allowed space for a significant indoor pool, along with a cinema room, a gym/games room, a sauna, and a steam room. Upstairs, there’s formal and informal living spaces and seven bedrooms, including a principal suite with dressing room. A lift serves all the floors, and there’s off-street parking for a number of cars behind electric gates. A private rear garden completes the super-prime package.
