A striking four-bedroom house, designed and built in 1969 by the architect David Tapp for his family. Located at the end of a private driveway, the house is surrounded by a large mature garden and is just a short walk from the centre of Henley-on-Thames and the river. With an emphasis on large swathes of glazing the house is particularly notable for its dramatic raised living room, its qualities of light and the wonderful blurring of the lines between internal and external space. The sitting room which sits on timber girders is not only a striking addition to the house, which creates a floating living space, but it also preserves a usable outdoor space underneath.
