soft first-story
n.— «The place Vogel calls home isn’t a “soft first-story,” the term used to describe a multistory building where parking is tucked beneath the units. Instead of load-bearing walls, narrow poles bear the brunt of the weight.» —“Bay Area news in brief” in Palo Alto Mercury News (San Jose, California) Apr. 14, 2006. (source: Double-Tongued Dictionary)
