The living room, which occupies the west side of the courtyard, is a simple, open space split into two zones by a large stone fireplace. Even though the space is simple, there are some things happening that are very smart: Clerestory windows face the alley on the west, bringing in light while maintaining privacy, and the ceiling along the walkway is lower than the adjacent ceiling, responding to the slope of the roof but also helping to further define the spaces.
