This project comprises a 400-squarefoot accessory dwelling unit (ADU), a 1,200-square-foot two-story addition to the main residence, and new landscape design. The homeowners, a young family seeking more space, wanted a solution that would allow them to stay in their neighborhood rather than relocate to a larger home. The renovation and addition to the main house included a full remodel of the kitchen, primary suite, two children’s bedrooms, and a half bath. The new ADU—designed as flexible space for guests and play has since evolved into a productive home office (adapting seamlessly to the family’s shift to remote work in early 2020). To meet the clients’ tight timeline, the project was strategically divided into three separate building permits, allowing construction to begin earlier and proceed efficiently. The ADU is conditioned with a high-efficiency heat pump system, contributing to the home’s overall energy performance.
