Why we work the way we do –


Renovate and Build

Renovation and building work includes: custom homes, additions, and renovations for residential and commercial clients. Fourth Pig produces high performance energy efficient buildings. Members are training and experienced with passive house (PH) building, net zero and carbon zero buildings.


Fourth Pig can be hired as a consultant on your project (such as around building envelopes and other passive house processes) or as a coach to help you through a project you are managing.


Fourth Pig members believe education is a crucial part of promoting more sustainable buildings.
The group offers workshops and consultations on: Passive houses, zero carbon building, net zero energy buildings, the basics of natural building and more.
You can also subscribe to “Force of Nature” e-newsletter (published by Fourth Pig) to learn more about natural and green design and building organizations, as well as news on climate change and renewable energy.
