Project Description

Cairns Creekside is a charming modern farmhouse in Langley, British Columbia. The 2-storey multigenerational home is an impressive example of efficiency in design and energy.

Designed by Draft on Site Services, the simple and charming modern farmhouse will house two families. As a result, the homeowners prioritized space functionality, overall comfort and long-term sustainability for their new home.

The home is designed to be a functional and comfortable space for two families. It features a master bedroom with ensuite on each floor, four additional bedrooms, a large family room with access to an outdoor living space, and spacious kitchen and dining area. The older couple will live on the lower ground floor, while the younger couple and their children live on the upper floor.

The long axis of the home is oriented westward from north to south to coincide with the natural contours of the land. Generous overhangs on the west façade protect from pervasive afternoon solar exposure. For additional solar  protection, a variety of high-performance glazing is used throughout the home. Every space also features large tilt and turn windows to provide effective natural ventilation; both interior and exterior shading systems will be used on all windows to further control solar heat gain.

The building envelope will consist of:

– R-28 Quad-Lock® Insulated Concrete Form below-grade crawl space wrapped with an additional 3 in. of EPS foam

– 2×6 wall assembly with R-20 batt insulation in the interior cavity and 6.75″ of exterior EPS insulation

– SIGA Majvest® facade membrane and SIGA Wigluv® adhesive tape

– Innotech Windows + Doors PHI-certified windows with true triple glazing

– Innotech Windows + Doors patio doors with Guardian Vacuum IG glass with nominal R-14

– R-76 net average roof assembly with blown cellulose and graphite-infused EPS

Construction is anticipated to be completed late 2019.
