The Gardens demonstrates that wood can be used to build attractive, affordable, high-quality housing from sustainable materials more quickly and efficiently than with other building materials. The project included eight factory-built, wood-framed units (four duplexes), which provide attractively-priced housing in Gibsons, where the cost of accommodation has been outpascing income growth by a rate of nearly three to one.
The two-bedroom homes were assembled at Click Modular Home’s factory in Port Mellon, 16 kilometres away from the site. Skilled framers had each of the units fully assembed in about four weeks; actual framing took just three days for each modular unit. Units for The Gardens were then transported to Gibsons in two pieces and connected on-site, ensuring the building envelope was watertight almost instantly. Using wood allows units to be easily modified if a customer wants some level of customization in the future.
Homes in The Gardens were framed using all-wood construction, with each half of the home engineered as a structural member so it could be easily transported and lifted into place with a crane on-site. Dimension lumber was used to frame the walls, with 2×6 spruce-pine-fir (SPF) studs for the exterior walls and 2×4 studs for the interior walls; the walls were sheathed with plywood for shear.
The main wall of each unit was supported by a parallel strand lumber engineered wood beam. The load-bearing beam in the floor of the one-storey units was comprised of a ring joist of four SPF 2x10s nailed together along with 2×10 wood joists topped by tongue-and-groove plywood. The underside of the floor was sealed with pressure-treated plywood for durability.
“It is a delight to live in our beautiful community here at The Gardens. We followed our house as it moved through the factory-build process and were amazed at the speed and efficiency of the prefabricated modular wood assembly system and the quality of the home”.
