Two storey 5-window range, 1-3-1 with outer bays advanced and carried up as angle towers. Castellated parapets with band below. Sash windows with pointed arches and with glazing bars interlaced at head. Four-centred arched entrance in flat roofed porch. Modern flat roofed extensions to rear.
Modernised, retains no original features of note.
Listed as an elaborately detailed early C19 boathouse retaining its original Gothic facade (notwithstanding alterations to rear); a prominent feature on the Menai Strait shoreline and forming a group with Porthamel Hall.
