Gardening opportunities are sharply defined by the seasons in New England’s variable climate. Our team was tasked with expanding the growing season for Newtonville, Massachusetts homeowners. The clients envisioned a structure that could perform double duty by serving as both a fully functional four season greenhouse as well as a comfortable home extension. The resulting 24’ x 11’ hybrid addition stunningly captures the sun’s rays while keeping the elements at bay. The project required careful architectural planning. Working in close collaboration with the team at Legault Design LLC of Concord, MA, Sunspace fabricated a custom aluminum framework that complements the home’s existing aesthetic. Our aluminum products have terrific strength-to-weight ratios allowing for slender profile lines that maximize glass areas without sacrificing structural integrity. Aluminum framing is also inherently resistant to the high humidity levels typical of a working greenhouse. This was doubly important given the space’s dual purpose. Another key to this greenhouse’s performance is found in its glazing. A glass structure intended for year-round habitation demands intelligent thermal management. We outfitted the enclosure with Cardinal Low-E 366 high-performance glass. Cardinal’s 1” thick insulated units, filled with argon gas, act as a crucial thermal barrier. These units also feature a specialized coating blocking 95% of damaging UV rays, enabling them to retain heat in the winter while reflecting it during the summer. The best modern glass technology allows spaces like this one to remain temperate sanctuaries in any environmental condition. This greenhouse’s design incorporates three expansive 42” x 60” awning windows to encourage natural airflow, and the 10′ folding glass wall system dissolves the boundary between the interior and exterior yard when fully opened. The seamless indoor-outdoor flow is perfect for summer entertaining or simply letting the space breathe. The space is instantly adaptable to the needs of the moment, whether shielding the home from harsh snows or thrown open to invite a summer breeze.
