There’s no question where the O House designed by Swiss architecture firm Philippe Stuebi Architekten gets its name. Located in Vierwaldstattersee, Switzerland, this luxury home overlooking Lake Lucerne features a number of circular-shaped openings in its facade, taking minimalist living in a bold new direction. Made using simple, traditional materials, this wood, concrete and glass house is executed in an innovative way. The “O”s offer a connection to the outdoors without compromising privacy, while interiors are ultra-modern and bathed in opulence, with cool, clean finishes providing a striking contrast to the natural views outside.
