Since quitting an office job to become a carpenter in 1960, Lloyd Kahn has developed a very keen sense of the artistry and craftsmanship of home building. Once a leading expert on geodesic dome houses, Kahn now favours smaller, simpler wooden homes, his own hand-built abode in California being a welcoming example. Jason Sussberg’s film Shelter is a window into the deep sense of accomplishment that drives Kahn to keep building, and a subtle nod to a notion of home that risks being lost to the Ikea generation, as all aspects of construction become more and more standardised.
