400 Westlake: Preserving Seattle History Through Modern Design
Developed by Martin Selig Real Estate, 400 Westlake is the greenest building of its size in the world. With a deep focus on sustainability, climate change mitigation and technology, 400 Westlake brings new meaning to a state-of-the-art building. Scheduled to be completed in the spring of 2023, it will be one of the first fully-developed properties in the Seattle Living Building program.
Focusing on energy conservation, 400 Westlake is designed to use 35% less energy than a typical office building. In addition to being energy efficient, 400 Westlake uses photovoltaic fins to collect energy during all daylight hours, generating 105% more energy than the building consumes. This puts 400 Westlake on track to be one of the first Net Zero compliant commercial buildings in Seattle.
400 Westlake also uses Seattle’s rain to its advantage. The building is designed to collect 100% of rainwater to be stored in a 107,000-gallon storage tank. The water is then treated and will be used onsite for landscaping, plumbing, and non-potable water uses.
At an impressive 15-stories added to Seattle’s historic Firestone Building, 400 Westlake combines modern design with historical preservation. In order to restore and preserve the façade, Martin Selig Real Estate worked with Lease Crutcher Lewis to design a series of braces as a supportive triangle between the upper and lower façade until the new structure was permanently attached.
400 Westlake doesn’t stop at world-class sustainability practices, it also offers expansive amenities for commercial tenants, including a 4,600 SF roof top terrace with views of the Space Needle and Lake Union, Shower Rooms, EV Charging Stations, Co-Working Space, and Secure Bike Storage. In addition to its expansive amenities, 400 Westlake offers over 230,000 SF with 11ft floor-to-ceiling windows, designed to provide the maximum amount of daylight to all interior spaces, including stairwells.
On top of stunning views and amenities, 400 Westlake’s location is hard to beat. 400 Westlake offers ample commercial and retail space in the heart of South Lake Union and Seattle’s tech hub. Surrounded by restaurants, fitness studios, coffee shops, and best-in-class residential projects, this building acts as a hub for pedestrians, bikers, and commuters looking to explore the neighborhood.
With over 230,000 SF available across 15 floors and two levels of below-ground parking, 400 Westlake offers A-Class office space for all your business needs. Contact our team today to learn more about our in-house construction, custom build outs, and exceptional service.
