Sustainable Builder Eli Spevak is a man on a mission. His projects are almost always about small living spaces, affordability, community, and twisting around or creatively using land use regulations to create interesting living communities. Everything from large shared housing projects to tiny houses, Eli is making his mark in the Tiny House Movement. While Eli seems low key, he’s actually a mover and shaker, interacting with land use planning officials, community leaders and other people focused on the increasing housing crisis.
