Previous Branch projects have included furniture, large-scale sculpture, architectural components, and pavilions. It fabricated a pavilion that SHoP Architects developed for the 2016 edition of Design Miami. Curve Appeal will be the company’s first complete building.

The house will sit on a conventional slab on grade but components such as its building envelope, interior partitions, and structural columns will be fabricated offsite starting later this year. The exterior wall modules, which will be various sizes, are to include the cellular matrix printed of carbon-fiber-reinforced ABS (Acrylonitrile butadiene styrene) plastic with glass-fiber reinforced concrete on the exterior and a gypsum-based finish on the interior. According to the project team, each composite wall section will have a compressive strength three to four times that of standard wood stud construction. In addition to being structurally robust, the assembly, which will also incorporate spray-foam insulation, will achieve R-values as high as 50. These thermal properties, along with features such as flexible film photovoltaic panels on the roof, are intended to help Curve Appeal achieve net-zero energy.

Since grants, in-kind donations, and sponsorships from manufacturers and industry organizations are helping realize the project, Boyd is unable to provide a hard cost. But he predicts that in the not so distant future a house like Curve Appeal could be built within a conventional construction budget. “Since this is the first of its kind,” he says, “it is not going to be the cheapest thing out there.”
