Art collectors Bruce Heavin and Lynda Weinman embarked on an ambitious project to build their dream house. Working hand-in-hand with architect Robin Donaldson over a period of six years resulted in an impressive, if slightly unconventional house, which seems to exist in tandem with the couple’s fascination for installations and sculptures playing with optical illusions and technical wizardry. Organised in two levels, in a circular layout punctuated by internal courtyards and openings that offer stunning views, the architecture is as much about working together with the topography of the site as it is about creating a spectacular object.
