Independent reading
A 5,010 sq ft Avanti-designed pinwheel house across nearly nine High Weald acres, with cinematic interiors, a recording studio, smart controls and an 18 kW solar-and-battery system.
The £699/sq ft guide is below many prime modern houses but the nine-acre setting and studio distort a simple density comparison; reconcile the rebuilt-house title, planning chronology, area components and energy records before valuing the premium.
