Time-lapse · Urban Studio · Etobicoke

Three Days. One Backyard Office.

Watch a Summerwood Urban Studio go from a bare pad to a finished exterior. The parts arrive cut and ready to assemble, so there's far less time with a crew in your yard.

Shown: the exterior build. Foundation, electrical and interior finishing are their own stages, and every site is different.
