Since its inception, Haycon has successfully delivered multi family residences, luxury homes, and commercial projects as a construction manager, architect, and owner. Haycon was founded by Patrick Haydon and David Bemiss, both architects with a passion for building and an inquisitive interest in the overall building delivery process.

Our approach from day one was to maximize efficiency in the design and construction of our projects. Whether we were the architects and builders or working in a collaborative effort with an architect, our approach to guiding the design and entitlement process is such that critical information for permitting, schedule, and costing is prioritized.

Our close collaboration with design consultants manages their scope to accurately provide only the essential documentation for the project. This eliminates unnecessary soft costs and planning efforts, while achieving a high quality finished product in a timely manner.

Haycon provides our clients a sma‍‍‍ll company experience and lean overhead structure while maintaining a level of professionalism and project accounting found in large companies. Our high level of professionalism and overar‍‍‍ching understanding of the construction process provides our clients with an extremely smooth building experience.”

Haycon Founders: Patrick Haydon & David Bemiss


Haycon was founded in 2007 by two architects, Patrick Haydon and David Bemiss, who envisioned a design-conscious firm committed to pursuing construction in a holistic and efficient manner. Our vision has since become a reality and Haycon's unique approach to construction has led to much success. Over the years, Haycon has become an award-winning design/build firm with a large and valuable network of professionals who inspire us as much as we inspire them. In the years to come, we’ll aspire to even greater achievements. One manner in which we hope to do so is through the pursuit of passive house design and construction. As Haycon has always sought to maximize efficiency in design and construction, this is a very natural and much anticipated evolution for our firm. We recognize the great need for more high performance/energy-efficient/passive house construction given the fact that about 39% of all carbon dioxide emissions in the US can be attributed to the building sector. 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, in our pursuit of passive house construction, we are prepping to undergo the PHIUS passive building certification process. In addition to that, we are eager to announce that we have formed partnerships with Amberline Windows, one of the top producers of high-performance European windows, as well as Boston Building Enclosures, who specializes in high-performance building envelopes. Amberline and BBE will aid and supply us with the services and products we need to construct buildings that meet passive house standards.

The National Preservation Awards, presented annually at the PastForward Conference, are bestowed on distinguished individuals, nonprofit organizations, public agencies and corporations whose skill and determination have given new meaning to their communities through preservation of our architectural and cultural heritage. These efforts include citizen attempts to save and maintain important landmarks; companies and craftsmen whose work restores the richness of the past; the vision of public officials who support preservation projects and legislation in their communities; and educators and journalists who help Americans understand the value of preservation.‍‍‍

Haycon is proud to volunteer for and support Youthbuild. There are at least 2.3 million low-income 16 – 24-year-olds in the United States who are neither in school nor employed.  Globally, over 200 million youth are working poor and earning less than $2.00 a day. All are in urgent need of pathways to jobs, education, entrepreneurship, and other opportunities leading to productive and contributing livelihoods. YouthBuild programs provide those pathways by unleashing the positive energy of low-income young people to rebuild their communities and their lives, breaking the cycle of poverty with a commitment to work, education, community, and family.
