Epping, NH – Chapman Construction/Design announced it has completed the construction of a new 2-story, 7,744sf wood-frame building which will serve as the headquarters for the Southeast Land Trust (SELT) of New Hampshire.

Located at 247 North River Road in Epping, the Nan and George Mathey Center for People and Nature at Burley Farm contains office and programming space to facilitate the organization’s nature-based programming. The first floor of The Mathey Center features the Pratt Family Community Room designed to be a meeting room for local organizations, “The Hive” volunteer room and a kitchen, while the second-floor houses flex space and an adjoining conference room.

“From the outside in, The Mathey Center reflects everything we hold dear as an organization,” said Brian Hart, executive director of SELT. “Our shared love of conservation, combined with the desire to bring our communities closer to the outdoors can be found woven through this new building, the centerpiece of the Burley Farms vision.”

The Pratt Family Community Room features locally milled ash timber cleared from the building site.

The fossil fuel-free building was constructed by Chapman using sustainable practices and operates at the highest building performance standards, including a high-performance building enclosure with continuous air vapor barrier and insulation to create a super-tight and well insulated building that will reduce energy loads. Wood framing was used to reduce embodied carbon, and locally sourced thermally modified wood was selected for its longevity. To limit solar heat gain during the summer cooling season and allow it during the winter heating season, new recessed windows and sunshades were installed to reduce loads and operational energy. The solar panels that line the roof combined with the five ground-mounted solar arrays can fully power both The Mathey Center and the adjacent farmhouse.

To protect the surrounding site and environment, Chapman worked alongside the NH Natural Heritage Bureau to develop a plan to ensure construction would not disrupt any rare animal species or “exemplary natural communities.” Tree clearing was selective and many trees that had to be taken down were hauled off site, milled, and used in the building as wall paneling, ceilings, beams, stairs, and wainscoting. A stormwater pollution protection plan was implemented to continuously monitor the site’s stormwater runoff and prevent potential hazards from contaminating water sources.

The project team also included Bruss Project Management, OPM; Sheldon Pennoyer Architects, architect; Altus Engineering, Inc., civil engineer; Roome & Guarracino, structural engineer; Design Day Mechanicals, Inc., HVAC and plumbing design; Electrical Systems Engineering, Inc., electrical power and lighting; Resilient Building Group, Inc., energy modeling; and SFC Engineering Partnership, Inc., code review and consulting.
