Among the award winners of the 100 Mile House Ideas Competition from the Architecture Foundation of British Columbia (AFBC) are a house featuring mushroom mycelium, lime-hemp plaster, and lime-pozzolan concrete; a net-zero-carbon and -energy home; and an affordable house featuring passive designs.  The competition challenged entrants to craft a four-person, 1,200-square-foot home using only building materials within a 100-mile radius of Vancouver, British Columbia, Canada.

The AFBC’s brief for the competition called for ideas on aesthetic, as well as technological, social, and economic sustainability. A hypothetical flat, corner site was used for context, and all city services such as water, natural gas, and electricity, were available to the proposed site. 

Perhaps owing to his knowledge of local materials, Vancouver native Tony Osborn took home first place for his Myco Home entry. His proposal emphasizes innovative materials, such as a mushroom-growing block system called Myco-Brix, as well as community-involved construction methods, whereby neighbors help build each other’s homes in exchange for future labor on their own structures. Osborn also detailed a phased construction plan through which the homebuilders might eventually recoup construction costs.

Other winners from the crop of 57 entries include the Zero E House (second prize), a net-zero energy residence designed by Neil Burford, Alex Pearson, and Joseph Thurrott; and New Model (third prize), an affordable home incorporating urban agriculture and passive design from Won Jin Park in New York, N.Y., A student prize was given to Laura Diaz and Dario Adail Ferrer of Madrid, Spain, for their design focusing on sustainable principles such as passive ventilation systems, use of recycled materials, and water reclamation., and an innovation prize was given to Renee Ferguson and Michelle Krochmal of Oyster Bay, N.Y., for their proposal, Bee House.
