Broadway Central Market, basement plans, 1927
Soon after its construction in 1927 it was renamed Broadway Market, and currently home to QFC, Urban Outfitters, and several other businesses.
Designed by architect Charles Haynes.
I wrote about Broadway Market for Capitol Hill Seattle blog, www.capitolhillseattle.com/2015/03/chs-retake-broadway-ma...
I included all of these blueprints with a description at ba-kground.com/broadway-market-blueprints/ .
From microfiche at the Seattle Department of Planning and Development, part of a larger set.
