Thanks to Adam and Lund Ophsal for the opportunity to visit the building. We have room for up to 10 people on the tour, so RSVP for your spot soon. We’ll start a waiting list if things fill up.

Autosport building tour

September 10, 3-4pm

2121 Westlake Ave, Seattle

Description:

The Autosport building was originally built in the 1920’s and is a two story building with a basement. The basement and first floor consist of reinforced concrete construction, the first and second floor walls are comprised of unreinforced masonry (URM), and the second floor and roof are wood construction. The project will remove and replace the roof, retrofit the existing structure below, and add two additional floors. The building will be approximately 26,000 square feet. The new use will be the Maximus/Minimus restaurant, Sugar Mountain Bakery, and offices.
The new lateral system consists of four special steel concentric braced frames, one at each exterior wall. The new floors are heavy timber framed with T&G and plywood sheathing. Existing floors will be re-sheathed with plywood and tied into the new braced frames. The existing URM walls will remain but additional framing and support will be installed to brace the URM walls for out of plane loading.
Sustainable features are the retrofit and reuse of existing materials and the extensive use of wood in new construction, both of which have lower embodied energy and carbon footprint than new steel or concrete. The project is not pursuing LEED certification, but will meet current Seattle Energy Code.
