We converted an existing 400 square foot garage -in the historic Hancock Park neighborhood of Los Angeles- into a one bedroom ADU. The garage sits on property lines on two sides and next to mature Ficus trees and an existing pool. Working within this constrained site, we maximized natural light to create a gracious one bedroom guest house. In addition to converting the garage, we renovated the backyard so that the new rear deck harmonizes with the guest house and pool, making this an ideal retreat for contemporary living.
