400 Westlake is a redevelopment of the two-story landmarked Firestone Tire building that is making a new kind of history as one of the most sustainable buildings of its size in the world. When redeveloped, the 1929 Art Deco building will generate more energy than it consumes, process water and waste on-site, use non-toxic materials and be resilient to certain natural disasters. SUSTAINABILITY: 400 Westlake is breaking sustainability barriers as the largest and tallest of five proposed buildings participating in Seattle’s Living Building Pilot Program and will be measured against stringent sustainability standards from the city and the International Living Future Institute. It will be the first project to use the ILFI’s Offsite Renewable Exception to create a hyper-sustainable building that includes: •Net Positive Energy •Offsite Renewable Energy •Resilience and Energy Storage •Water Reuse •Human Health and Wellness HISTORIC PRESERVATION: Terra cotta ornament on the south and west facades are characteristic of the Art Deco style. This, along with fluted piers, exterior windows, scalloped spandrel decorations, and original embossed Firestone crests will be meticulously restored. This is a story of sustainability in the broadest sense—economic, cultural, and environmental. PROGRAM: The newly designed building includes an addition of a 13-story office tower and two levels of underground parking. The ground floor of the historic Firestone building will offer 789 square meters of retail space. The office tower is designed with a flexible open plan and side core to attract tech tenants.
