We are exploring just this at our January 24th engagement session. Are tiny houses feasible in our region in terms of waste water, solar energy and whether they are used as single or multiple units. Tiny houses can be completely self-contained and off-grid; however, cities are risk-averse and rightfully so. We are looking at two models: tied to the system in terms of water, sewage and electricity, and not, and how they differ and meet our cities' health, sustainability (green) and housing strategies and goals. Currently, many tiny houses are being built to RV/CSA standards, and have external hookups. We are wanting to test how innovative we can go and whether green technologies can work with tiny living and still remain safe, sustainable and affordable. More on us at bctinyhousecollective.com.
