Independent reading
A 9,526 sq ft 2015 contemporary house in Burwood Park, combining seven suites, five reception rooms, cinema, wine cellar, Control4 and a heated outdoor pool.
Langton clears the Pavello standard through its coherent contemporary build, south-facing 0.6-acre setting, exceptional entertaining scale and integrated leisure-and-technology programme. The £625 per sq ft working density uses the exact-address 9,526 sq ft record, not the looser over-10,000-sq-ft marketing claim. The decisive diligence gate is a signed component schedule joined to the 2015 completion archive and the private-estate title and charge pack.

£625/sq ft from current guide and 9,526 sq ft exact-address transaction-derived internal-area record; the current publisher markets over 10,000 sq ft, so a signed RICS component schedule must reconcile the difference.
