We renovate, build, consult, and educate.

We work primarily in the GTA, the Golden Horseshoe and Muskoka areas of Ontario.

 Our mission is to foster ecologically balanced methods of construction and energy production in order to promote more sustainable and healthy communities. Founded in 2007 the Fourth Pig is a non-profit worker co-operative that is owned and operated by its members. Our members are invested in the success of the organization and we are proud to share and promote cooperative values.

Buildings can be low carbon and climate change resistant and this can have a big impact. Sustainable building means a cleaner environment, more efficient energy generation and use, more effective use of building materials, and healthier living spaces. The result is comfortable buildings that are good for the planet and good for your health.

renovate/build

Our work includes custom homes, additions, and renovations for residential and commercial clients. See below for some sample projects and here for a PDF of our portfolio. 

We produce high performance buildings. We pay close attention to the embodied carbon and the health impacts of our materials. We re-use and recycle materials. We are trained and experienced with passive house (PH) building, net zero and carbon zero buildings.

We recommend the principles of an “integrated design process” for projects. This approach brings together the key stakeholders (owners, architects, engineers, tradespeople and others) to create a project plan.
