Project Description

Nick Bray Architecture is designing and building a high-performance, innovative and sustainable Certified Passive House. With our partners, we aim to showcase the direction that housing in BC will be moving. With the introduction of the Step Code, the BC government and City of Vancouver have set the challenging target of all housing being built to a similar performance standard by 2032. One of the many interesting aspects of the project is it being a modest size home built on an accessible budget, rather than the typical big budget and palatial Passive Houses in BC.

The project uses and tests innovative materials and technologies to overcome the many challenges it faces, including an integrated piling/shoring system, ICF foundations, HELIX concrete additive, SIPs panels, new eco-friendly spray-on membranes, fire-shutters etc. The challenges include:

  • building on a narrow 25′ wide lot [implications on PH modelling and fire spread]
  • building in a peat bog / high-watertable, requiring an extensive piling/shoring system
  • building to be earthquake resistant.
  • designing for flexibility and space efficiency [using a split level design to fit 5 double bedrooms and 5 bathrooms into a 2,250sf house].
  • building for longevity [100 years +].
  • designing to generate renewable energy.
