Passive House Building

We recognize the need for greater energy efficiency and green building practices within the Boston construction industry. We want to do our part in reducing emissions and creating buildings that improve the health and well-being of those who inhabit them. So, we design and build according to passive house standards.

We also recognize the benefits that high performance and passive buildings provide. Not only are they better for us and for the environment, they also happen to be very cost-effective. Haycon is committed to creating spaces that provide a high quality of living at a reasonable cost.

"Haycon has been instrumental in executing our vision, supporting our preconstruction efforts and fitting seamlessly into our project team from the start. The performance of this property speaks for itself as we are on schedule and on budget despite delays and complications as a result of the COVID-19 pandemic. Patrick’s leadership is only exceeded by his trustworthiness and dedication to our goals, and his staff have followed suit. The entire team possesses the necessary experience to execute effectively and has catered to our unique reporting requirements along the way. "

"Another great project by Haycon. They keep advancing and improving their builds. Every step of the way, they learn and improve. They definitely don't use the phrase 'We've been doing it this way for 30 years."
