Per the owners' request, the home is ultra efficient with an insulated concrete form (ICF) that creates a thermally broken shell for the home and helps maximize the efficiency of the radiant floor heating. A-Series windows with triple-pane glass were selected because they offered the performance needed and are available in large sizes. “It can be difficult to find large direct-glaze units from a well-known, reputable company,” Coyle said. “Andersen was that company for us.” The home also includes a solar array providing clean energy and passive heating and cooling strategies, like a heat chimney that rises from the centrally located stairs and helps to funnel hot air out and cooler air in through a venting skylight. In trademark MaMo style, the heat chimney nods to the building’s typology without bowing to a traditional design since it functions like a cupola would on a historic barn.

The owners wanted a low-maintenance home. To that end, the building envelope is made to last with high-performance windows, virtually weatherproof shou sugi ban and metal siding over a concrete shell, and a standing seam metal roof. The industrial materials nod to the utility of the building type while the consistent use of black creates a striking modern aesthetic.
