The building’s primary organs, or “barnacles,” inspired by marine crustaceans, manage water, energy, light and ventilation. They function both vertically and horizontally, in the form of large extruded skylights and window bays. Sliding panels made with repurposed sails and wooden slats frame the primary multipurpose space, allowing it to be fully enclosed in the summer or fully open in the winter. The structure is composed of reused CLT panels, framing the building’s core and storage wall, and columns of Sassafras tree trunks from the island.
