Independent reading
A rigorously contemporary 2017 Thames-side house with five suites, cinema, gym, sauna, 1.12 private acres, a quadruple garage and its own mooring.
Moonraker clears the Pavello benchmark through unmistakably modern design, high-specification interiors, privacy, landscaped Thames frontage and an exceptional leisure and motoring programme. The £5m guide is about £828/sq ft on the 6,040 sq ft portal headline, but the narrative describes about 3,400 sq ft of main accommodation and the exact-address EPC-derived record shows 454 m², about 4,887 sq ft. A signed component schedule must separate the house, basement, garage and ancillary rooms before any density comparison is treated as value.

Identity confidence99%
Moonraker, Stonehouse Lane, Cookham, Maidenhead
The live Savills instruction and current Rightmove and OnTheMarket records align on Moonraker, Stonehouse Lane, Cookham, SL6 9TP: £5m, detached, freehold, five bedrooms, six bathrooms, a 6,040 sq ft headline, 1.12 acres, EPC B and the same river frontage, mooring, basement leisure rooms and quadruple-garage programme. UPRN 100081050574, exact-address EPC context, a £2.6m June 2020 transfer and exact-address planning records independently bridge the marketed asset to the legal address. The title number, registered river boundary and component-area schedule remain conveyancing evidence rather than assumptions.
