The Los Angeles Design Festival is spotlighting architect-designed granny flats with a series of tours this week. Here are look at four of the city's best.
ADUs, or Assisted Dwelling Units, have become more popular in California since it made changes to state laws.
Facing housing shortages and rising rents prices, the state wanted to find a quick and easy way to provide affordable housing, so ruled that homeowners could build "accessory units" on their properties, as long as they have a kitchen and bathroom.
The small-scale properties, often nicknamed granny flats or in-law units, are typically built in back gardens and rented out for profit.
The Los Angeles Design Festival, which takes place from 20 to 23 June, is spotlighting the trend with its ADU Home Tour. It is offering tours of several architect-designed ADUs across the city, in areas including downtown, Highland Park and Echo Park. US editor Eleanor Gibson picks out the four best ones to visit:

Bunch

Highland Park
Architects and partners Bo and Hisako, who run Bunch Design together, built this 850-square-foot property in the city's Highland Park neighbourhood for themselves.
The ADU has a stepped ceiling, propped up by staggered wooden columns, along with skylights and flashes of colour that help create a bright interior. The exterior is a simple gabled form with a rough stucco surface to help it blend in with its surroundings.
