Light-filled, double-height living room of a residence at Trillium Townhomes. The room is characterized by its soaring double-height ceilings and crisp white walls, which amplify the sense of openness and light. A large, saucer-shaped Nelson Bubble Lamp hangs prominently from the high ceiling, serving as a mid-century modern focal point.

Overlook Cohousing
A modern farmhouse or craftsman-inspired aesthetic with a simple, two-story gabled roofline. It is clad in pale yellow horizontal lap siding, accented by white trim around the windows, doors, and porch columns. The upper gable features matching yellow shingle siding, adding texture to the design. A prominent, covered front porch serves as a central feature, supported by substantial white columns and enclosed by a natural wood railing.

For me, living in a zero energy community inspires me to think about what I can do to reduce my impact on the environment. I want to leave this planet better for my grandkids, and it feels good to be part of a community of people who feel the same way.

The Green Hammer team was phenomenal in many ways. They worked as a cohesive team that delivered the highest quality building in an exceptionally short span of time.
