An imposing 11-bedroom detached mansion on The Bishops Avenue, offering nearly 9,900 sq ft across four floors with lift access. The house combines grand reception spaces, a principal suite with dressing room, separate staff accommodation and a sizable indoor pool — well suited to an established family seeking space, privacy and formal entertaining areas.
The plot is exceptionally large, with a carriage driveway, secure off-street parking and mature, landscaped gardens that enhance privacy. Practical features include multiple reception rooms, two kitchens (including staff kitchen on the lower ground), extensive plant and utility rooms, and 11 bathrooms — a property laid out for both family life and live-in staff.
Buyers should note this is a 1930s solid-brick house: glazing install dates are unknown and walls are likely uninsulated, so energy efficiency will be limited. Broadband speeds are slow in the area and running costs (including very high council tax and mains gas heating across a huge footprint) will be significant. The scale and age of the house also mean there will be ongoing maintenance and potential for modernisation.
This home will best suit purchasers seeking a large, characterful London residence with scope to update services and fabric, or investors looking for a unique, high-value asset in a very affluent location close to Hampstead Heath and top local schools.
