Architecture

Designers Christopher Robertson and Vivi Nguyen-Robertson conceived their house as an unfolding sequence of simple geometric forms: a low concrete wall, a concrete cube, and a boxclad in Siberian larch.

When Belgian fashion retailer Nathalie Vandemoortele was seeking a new nest for her brood, she stumbled upon a fortresslike house in the countryside designed in 1972 by a pair of Ghent architects, Johan Raman and Fritz Schaffrath. While the Brutalist concrete architecture and petite but lush gardens suited her tastes to a tee, the interiors needed a few updates.

AIA architect David Hertz, known for 747 Wing House, looked to the structure of a butterfly wing when designing this Venice home. The inverted roof of Silver Triangle House (or Butterfly House) captures water that collects in a sump and is used for subsurface irrigation. The roof is just one of the home's sustainable features, which, Hertz says, "are not compromises to the design; they're part of the design." Photo by Laura Doss.
