Regarded for its ambition, scope and innovation, this Grade II-listed house in Cambridgeshire epitomises mid-century architecture's impulse to seek out new modes of living. Its strikingly conceptual form was designed by architects Barry Gasson and John Meunier and was added to by Viran Sahai OBE in 1997, who incorporated a new entrance and a geodesic dome, currently used as an artist’s studio. Playing with partitions, a spiral, almost Guggenheim-esque ramp wraps around the house's core, gently delineating zones for playing, relaxing and entertaining.
