A 1930s showroom. Restored, not demolished.
Before the residences, the corner belonged to the automobile: the Pierce-Arrow showroom, built in the 1930s. The developers’ stated vision is restoration and celebration of the heritage base — and fifty-eight residences rising from it.
A luxury marque’s showroom, kept as the base of a residence.
Pierce-Arrow built luxury automobiles; this corner held its Toronto showroom. The stated intent for 1 Marlborough is not to clear the site but to restore what stands — the new building takes its address, and its ground, from the old one.

Stated Vision · Devron × Dorsay05 — The Neighbourhood · Summerhill
Summerhill. Where Rosedale meets Yonge Street.
Summerhill holds the west side of Yonge Street here; Rosedale, the east. These are among Toronto’s longest-established addresses — neighbourhoods that seldom make room for a new one. The southwest corner of Yonge & Marlborough is exactly that.
