Passive House Guest Cottage in Bellevue - Construction began Fall 2025 by Triple Bottom Line

Designed for multigenerational living on a shared site, this new home prioritizes flexible use and aging in place.
A spacious great room on the upper level, expansive openings, and tiered outdoor spaces maximize views and facilitate connection with the tranquil, forested site.
Passive House design principles ensure that the home will be resilient, highly energy efficient, quiet, and healthy to occupy.
