TKWA Seattle is a hub for our ongoing design work in the western United States and China. The studio office incorporates many ‘Passivhaus’ sustainable features, including a 10kw photovoltaic system, highly insulated building shell and glazing, southern exposure for natural daylight, strong indoor-outdoor connections, as well as recycled content and low VOC building and finish materials. The upper level studio also offers outstanding views of Lake Washington and the mountains beyond.
