Haycon is an award-winning Design/Build firm dedicated to innovating and diversifying Boston's built environment through our high-performance and Passive House building. The company was founded by Patrick Haydon and David Bemiss, two architects with a passion for, and interest in, the building delivery process.

Our broad scope of services include pre-construction, construction management, design-assist, construction, and general contracting.

Haycon's approach to guiding the design and entitlement process is such that critical information for permitting, scheduling, and cost is prioritized. We make sure to eliminate unnecessary soft costs and planning efforts in order to produce high-quality finished products in a timely manner.
