Fourth Pig Green & Natural Construction uses its extensive experience to create naturally great buildings. 

Our Mission

Our mission is to foster ecologically balanced methods of construction and energy production in order to promote more sustainable and healthy communities. 

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


Our Services

We are a full service construction company (that loves to provide education on green building). From renovations to design-build we offer general green and natural contracting and construction. We are trained and experienced with Passive House (PH) building. Ask us about PH, net zero and carbon zero buildings (including pre-fabrication).

Our work includes custom homes, additions, and renovations for residential and commercial clients.  We produce high performance buildings. 

We can be hired as a coach to help you through a project you are managing, consultant on your project (such as around energy efficiency, materials selection), subcontracted for a specific building component of your project (such as framing or earth plaster), or hired to act as general contractors from the beginning of the design process to completion of your project.  See some sample projects here. See the bios of key staff here.

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

All of our work is based on natural and green building techniques and materials. 

Members of the Fourth Pig bring years of experience in natural building including straw bale homes, green retro-fitting, cob, rammed earth, earth bag, post and beam, passive and active solar design and installation, as well as years of adult education experience.  

Our sustainable shelter model has many features including: 

•natural, non-toxic and health-focused materials and design
•life-cycle management of building materials
•local materials sourcing
•solar design for efficient heating, cooling, lighting
•energy conservation measures

Sustainable building means a cleaner environment, more efficient energy generation and use, more effective use of building materials, less toxic living spaces. 

The Fourth Pig is also committed to education as a crucial part of promoting more sustainable shelters. We host presentations and provide hands-on workshops. We can also incorporate education into construction projects and can be hired as information/education consultants. Learn more here
