Offering panoramic views of downtown Seattle, this sweet pad is located on Lake Union. Given a limited allowable footprint and the desire of the owner to maximize both interior living and outdoor entertaining spaces, the plan flips the typical residential model by locating public spaces on the upper level and private spaces on the entry level. This strategy allows for the consolidation of entertaining spaces in one large space on the upper level with direct access by circular stair to a rooftop deck. In response to environmental concerns, the location and treatment of glazing promote passive heating and cooling while providing abundant natural light. Sun screens and overhangs provide effective summer shading. Efficient hydronic in-floor heating utilizes an energy efficient heat pump system and the fresh air ventilation system utilizes an energy saving heat exchanger.
