Shanty Wijaya, founder of LA boutique real estate renovation firm Allprace, converted a two-car garage in California, USA into a chic ADU complete with a kitchenette, bedroom and bathroom. The snug space has plumbing, electrics and a HVAC system, so comfort is guaranteed. The striking black exterior complements the modern backyard, while internal white shiplap walls increase the sense of space in the 400-square-foot annexe. According to Forbes, the rising popularity of house sharing has, in some communities, made garage conversion permits more difficult to obtain. Before beginning a similar project in the US, look into local requirements for turning vehicle space into habitable space.
