Finding inspiration in the work of Tadao Ando, a Houston couple designed the concrete house of their dreams. 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. The inside décor is rather minimalist yet very inviting, though there’s a lot of concrete in design, warm-colored wood and neutral colors make it cozier. Located off the kitchen, Vivi’s office disappears behind sliding walls covered in black chalkboard paint. The low windows in the master bedroom focus the view on the backyard, not the neighbors, and the bed is placed on a platform for the same reason. This residence looks really relaxing and it invites you to spend there as much time as you have.
