Our clients asked us to design an addition that included a lap pool, an exercise room, and a relatively remote main bedroom for a growing family. The program suggested a more modern approach to detailing and technology. The indoor pool incorporates current glazing systems that enable it to completely open up to the outdoors during the summer months. A roll-down screen system hidden within the ceiling provides protection from insects. The pool is set in a heated concrete slab with an integrated cover for energy conservation and for the safety of young children. The stairway within the two-story glass connector is deliberately light and open, providing transparency and signaling a shift to the addition. A series of stone retaining walls terrace up the existing grades to a private outdoor garden off the main bedroom and study.
