How’s this for a clever idea for adding a window in a small bathroom? With just one exterior wall, the area above the sink is a natural spot for a window. But what about a vanity mirror? Architects Albert and Lisa Skiles came up with the idea of a sliding mirror, so you can move it over the window and use as a vanity, or slide it to the side for sunlight. Sleek space-savings! We love the geometric shapes in this new master bathroom too, including the inverted L of the walk-in shower doorway. See the rest of this gorgeous (and green!) master bedroom and bath addition here.
