In the more desirable neighborhoods of Vancouver, the alleys are lined with little houses. Technically called “laneway houses” (Canadians use the term “lane” rather than “alley”), they are part of Vancouver’s eco-density and affordable housing strategies. Eco-density is the idea that higher density cities support transit use and a smaller per capita ecological footprint. In Vancouver, BC. a limited supply of land and large pressure from foreign immigrants means astronomical house prices so demand is strong for even a tiny house fronting the alley. Dr. Bjelland is researching Vancouver’s eco-density strategy, its successes and contradictions.
