Quacks House
38C Mount Avenue, Ealing, Greater London
Film by The Agency Group
Independent reading
A £4m, 6,349 sq ft gated contemporary resort-house with a 37ft indoor pool, gym, sauna, cinema, roof-terrace jacuzzi and west-facing garden in Ealing.
Quacks House clears the Pavello benchmark through exceptional contemporary scale, rare private-leisure architecture, ambitious interiors and gated seclusion in London. The £630/sq ft headline uses the current marketed 6,349 sq ft, while an exact-address record gives 5,167 sq ft and the original 2013 permission described only 198 sq m. A signed component measurement and the complete later approval and completion trail are therefore essential valuation inputs.

Quacks House, 38C Mount Avenue, Ealing, London
The live Savills and Rightmove instructions, Fine & Country's current exact-address instruction, exact named-property transaction and address records, and property-specific planning evidence all align on Quacks House, 38C Mount Avenue, Ealing, London, W5 2QJ. The current market sources uniquely agree on a detached freehold house at a £4m guide with four bedrooms, four bathrooms, approximately 6,349 sq ft and a 37ft indoor pool. The publisher-controlled film shows the same named Mount Avenue property and amenity programme. The title number and UPRN remain unconnected, but the unique name, complete address, development history and specification produce a decisive exact-property match.
