Earth Dragon Farm

is an organic farm centred around a home built based on the most advanced green building certification program in the world ~ the Living Building Challenge.

This 1288 square foot home, like many green homes, employs passive solar design, daylighting, roof top solar electricity, solar domestic hot water and rain water harvesting.  Unlike many other deep green homes in BC, it is a natural home made primarily from straw, stone and earth.  It also employs an active solar heating system, composting toilet, seasonal greywater system and a super-insulated envelope that is close to Passivhaus standard. Unlike many straw bale homes in a northern climate, it does all this as a fully 'natural building' with natural earthen and lime plaster wall finishes and a limited amount of high-carbon-footprint concrete.  The property and home design also employ principles of resiliency and use of appropriate materials and technology, with as local sourcing as possible and following permaculture design principles.  

[The website will be updated in 2018 with home photos, course info and dates.  

Thanks for your patience.]
