Hunter House

Straw-Bale Off-Grid Passive Solar House near Peterborough

A contemporary straw-bale home built entirely off-grid in rural Ontario, the Hunter House reaffirms the benefits of natural building techniques in 21st-century construction, and is a testament to SUSTAINABLE.TO’s commitment to sustainability and to the use of renewable resources. The combination of effective straw bale insulation, energy-efficient doors and windows, solar thermal hot water, deep overhangs for sun shading, highly-reflective Galvalume roofing, thermal mass concrete floors, hydronic radiant floor heating, and on-site solar & wind energy generation & storage make the Hunter House comfortable, healthy, and extremely resilient.

Since completion of the main house, SUSTAINABLE.TO has been retained to design two more complementary structures: a Work/Storage Shed using as many ‘left over’ materials as possible from the original construction, and a Sugar Shack/Vehicle Maintenance Shed nestled into the original barn stone foundations.
