About Us

For more than 30 years, Healthy Buildings has been changing people’s lives. Built beyond green, our buildings contribute to a healthy future by creating places to live, work, and learn that advance sustainable technologies, optimize energy performance, conserve valuable resources, and create comfortable indoor environments with less toxic chemicals and more fresh air and natural sunlight.

Using our proprietary green construction technologies, we have also changed the state of green building design and construction. We deliver high-performance, cost-effective homes and buildings, accomplishing this through a spirit of teamwork, creativity, and innovation.

In addition to design and construction services for development companies like our partner, Thriving Communities, we provide technical advisory, development management, and analysis along with LEED® consultation services to project owners, architects, and engineers looking to elevate their projects to a more environmentally responsible level.
