Seattle, Washington | 800 square feet

Although Brom’s property is only 0.13 acres, it’s large enough to accommodate two homes, a patio, a lawn and a garage. A slatted wood fence with a gate divides the space between the two houses and provides privacy.

There’s a powder room, open kitchen and living room on the first floor, with a bedroom and bathroom upstairs.

Evelyn Brom’s plan was to build a backyard cottage and rent it out. She would keep living in her two-bedroom home.

AH-HA MOMENT: As the design developed, Brom realized that she wanted to live in the stunning wood-and-glass ADU. It was a good decision. A week before moving in, Brom was laid off from her job.

REAL LIFE: The $3,000 a month Brom receives in rent for the main house (which is occupied by a three-generation family) provides a needed income. “Being laid off has made this arrangement a lifesaver,” Brom says. If the stairs in the cottage ever become too hard to navigate, she can move back into her original one-story house and rent out the cottage instead. “Now I have options,” she says.
