Details

This Detached Accessory Dwelling Unit project is an intergenerational living space built for the owners’ grandparents, with an 800 sq ft garage and a 450 sq ft, one-bedroom apartment. The garage meets the parking requirements while the apartment is solar-oriented and provides stunning views of Bellingham Bay. The project is designed to meet the Passive House standard with energy-efficient features, such as high-performance windows, HRV, and a mini-split heat pump. The Heat pump water heater in the garage provides domestic hot water needs and saves space in the apartment.
