This is a Room to Move home in New Zealand.
It’s a super solar-powered house built from SIPs. New Atlas wrote:
Ex-boat builder and carpenter Jeff Hobbs from New Zealand-based studio Room to Move was recently commissioned to build a special bespoke tiny house for local resident Briar Hale. The 23.95 sq m (257.8 sq ft) house was built using structural insulated panels (SIPs) made from plywood and foam; recycled wood materials and sports multiple off-grid solutions. Hobbs chose to build the home using 62 mm (2.45 in) thick SIPs due to their lightweight, strength, durability and excellent insulation qualities, and also meant that he had extra floor space to work with when designing the home’s interior.
