About this plan
A 24' × 20' backyard cottage, also called an ADU or granny flat: one bedroom, a bathroom, a laundry nook and an open kitchen and living room, set in a small garden with trees and shrubs.
It suits a rental unit behind a house, a home for a relative, or a first look at what fits on your lot.
4 rooms over 439.5 ft²: living and kitchen (263.3 ft²), bedroom (99.8 ft²), bathroom (38.3 ft²), laundry (38.3 ft²).
What people change
- Move the cottage within the garden to keep the setbacks your town requires.
- Turn the laundry into a second closet, or add a porch along the garden side.
