Aurora, Esher (single dwelling)

This is an extraordinary house. 6000ft² of top-notch spec, in an extraordinary setting - 1½ landscaped acres running alongside the River Mole. An extraordinary basement: with garaging, swimming pool, gym, hot tub and games room. Two extraordinary storeys of living space, made possible by a lightweight steel frame supporting the cantilevered terraces and all that glasswork. And perhaps most extraordinary of all: this was a speculative development. To you? £3½ million.
