Why Factory-Built

Affordable

A prefabricated, efficient build process needs less time and less labour on site, and that shows up in the price.

Sustainable

Clean construction methods and renewable materials from local, sustainably managed forests — including a cross-laminated timber floor plate.

Customizable

Every unit is expandable and modular, with interior and exterior options you pick during design.

Prefabricated

Built indoors in a controlled environment, so weather and the usual site delays never touch the structure.

Turnkey

We handle everything: feasibility, permitting, design, factory order, site prep, foundation, utilities, and install.

Timeline

From order to delivery can take as little as 12 weeks, with site prep running in parallel.

CSA A277 Certified

Every unit is CSA A277 certified, factory-inspected to the same code standard as site-built construction.

Canadian Made

Handcrafted in the Fraser Valley, British Columbia — a two-hour drive from Bellingham.
