The custom Baltic birch furnishings in the master bedroom are by John Large of Parsonsfield. Tim Greene, also of Parsonsfield, created the galvanized steel accents—including bedside tabletops with holes for phone charging—from an old style of metal with large brushstroke-like flecks, known as “spangle.” In the shower area, Greene made a small wall-mounted cabinet that doubles as an exhaust vent and a casement window for one of the original spyholes.
