Where we build GREAT BARNS, it’s that Simple!

…and this is who we are                                             

 Second generation Timber Framed builders, our roots are strong in New England from early childhood in the country-setting of the Berkshires to coastal Cape Cod, where our family established a precedent for these uniquely constructed buildings. Following in the footsteps of the late James (Dennis) McGrath, Great Barns proudly continues his legacy and is committed to the kind of quality craftsmanship he represented. As our designs expand and become generationally different, they stay true to the strong New England roots and maintain their functionality.

Great Barns embarked on a 8 week project constructing 4 new buildings and renovating the kitchen/food building as well as the many pool cabanas as seen on site. This project was a high profile, highly anticipated water park grand opening with loads of detail and long hours of labor. Restroom buildings, pool cabanas, pump house, wave buildings were all build to spec on site with our highly skilled crew. It was a daunting task at times but one to be proud of and in completed in record time. We were pleased to be part of this project!
