The Planar House in Paradise Valley, Arizona, conceived by artistically inclined architect Steven Holl, is a 3,200-sq.-ft. single-family prefab home designed to house its owner’s private collection of fine art. This modern design itself is a strong contender the modern artworks that it displays within. “This home is to be a part of, and vessel for, a large contemporary art collection. Great 20th-century works by Bruce Nauman, Robert Ryman, Jeff Koons and Jannis Kounellis are part of the collection,” according to the architect. The facade is simple, boasting concrete and accented with aged, perforated Cor-Ten steel. The home’s interior is designed in three main living areas – the front of the home featuring a garage, master bedroom and library; the rear boasting the kitchen, dining room, a study leading to the outdoor pool and court yard; and the gallery space and living area in set between front and rear. Finishes are minimalist – the perfect backdrop for the vivid art pieces. A serene rooftop garden raises residents to new heights of serenity. Steven Holl Architects.
