Devon, £2.75 million

Wall-to-wall light is the USP at ‘architectural masterpiece’ Broad Park, with its cathedral-esque atrium, floating staircase, glass bridge and full-height windows galore. Dazzling views of the South Hams wrap around the house, impossible to ignore thanks to sliding glass walls, terraces and balconies. On the edge of Broadhempston, near Totnes, there are four bedrooms (two en suite) and a separate outbuilding has been converted into a double-height dining hall with adjoining kitchen flanked by glass-fronted, temperature-controlled wine cellars to fit 3,000 bottles. Outside, 15¼ acres include lawns, paddocks, four-car garage, stable yard and tack room; heating, lighting and alarms are controlled via apps and further high-tech gadgets include remote-controlled digital showers and automated roof windows.
