Meet David Long
DAE — Design Architecture Everyday Inc. is a boutique architecture firm in Vancouver, based at 1828 Powell Street. David Long and Antoine Morris founded the practice. Between them they have about 20 years of work in project management and design, covering rezoning, permit applications, and construction.
David Long is registered with the Architectural Institute of British Columbia (AIBC) and the Ontario Association of Architects (OAA). Before DAE, he led projects through the rezoning and development-permit process at Gair Williamson Architects, acting as Project Architect on mixed-use and residential buildings.
The firm works across multiplex and missing-middle housing, townhouses, mid-rise apartments, single-family additions and new builds, and commercial fit-outs such as cafes and restaurants. DAE designed the WILLA multiplex in Vancouver and the 6162 Granville SSMUH project. The team includes architects Shirley Liu (AIBC) and Tom F. Caminha, plus intern architect Nanxi Liu.
Earlier in David’s career, his product and furniture design work picked up several juried awards, including the Best of Canada recognition from Canadian Interiors Magazine in 2010 and a Juror’s Choice award at Toronto Design Week in 2013.

Why work with David
01
Full lifecycle, one team
Rezoning, permits, and construction administration are all in scope. David ran rezoning and development-permit work at Gair Williamson Architects before founding DAE, so the early municipal steps that decide a multiplex schedule are handled in-house.
02
SSMUH track record
DAE designed the 6162 Granville project, which the City of Vancouver approved in February 2026. It takes a 1920s single-family house and turns the lot into six units by expanding the existing home and adding a laneway home — a worked example of the retain-and-add-units approach.
03
Registered in two provinces
David Long holds both AIBC and OAA registration. For a multiplex, that means stamped architectural drawings from a licensed architect, not a designer working without a seal.
