Meet David Long
DAE is a dynamic, full-service architecture practice based in Vancouver. Founding principal David Long, registered AIBC, brings 13 years of experience navigating the building industry from rezoning through construction.
DAE has worked on multiplex projects across Vancouver, including the boutique 5-unit WILLA multiplex by Lightwell Homes in Vancouver West, and a SSMUH project at 6162 Granville Street that received city approval in February — converting a single-family lot into six residential units through an expansion of the existing home and the addition of a laneway home.
The firm has received recognition from WL Designer of the Year, the American Architecture Prize, Dezeen Awards, and the AIBC Awards.

Why work with David
01
Full lifecycle, one team
Rezoning, permits, and construction administration are all in scope. Useful when the project involves SSMUH retention of an existing house plus addition + laneway, where mistakes early cost months later.
02
SSMUH track record
The 6162 Granville approval is one of the better-documented SSMUH approvals in Vancouver — useful precedent for any project trying to do the retain-and-add-units pattern.
