we approach residential construction in a distinctive way

While Grain HPH can help you with general contracting, project management, various construction services, fine carpentry and custom furniture, implementation of high design and sustainability is our specialty.

The American archetypal residence that dots our suburban landscape leaves room for significant improvement. At Grain, we believe every home and project should be unique; each guided by the personality of its environment and owner. When we let these principles inform our designs and construction practices the quality of our habitats, and even our lives, can change for the better.
