Haven Fort Hotel

This is a large marine villa, likely dating to the 18th or 19th century. The exterior is constructed of rock-faced rubble stone in large squared blocks, with slate roofs, and chimneys have been removed. It has an L-shaped plan, with two storeys and an attic. The west gable, facing the sea, features heavy stepped corbelling to the verges and raised cornerstones. The attic window has a pointed shape with Y-tracery to the toplight of a two-light casement. Two larger, pointed first-floor windows also have Y-tracery toplights to casement pairs. A broad, pointed ground-floor window has triple casements and intersecting tracery to its toplight. The north front has a three-window range. The left side has cambered-headed triple casements, each with a toplight, on both floors, with the ground-floor window being larger. A large stone porch with a flat roof and parapets, with coped taller angle piers, is centrally located. Two small, pointed lancet windows with lattice glazing are present on the front, mirroring the style of the door on the east and west sides. Above this is a pointed window with Y-tracery to a casement-pair. The first floor to the right also has a similar window over two that are akin to the ground floor window to the right.

A single-storey dining room, a 20th-century addition, is situated on the south side, connected at an angle to the southeast rear wing. The rear wing's west side features two cambered-headed triple casements with top-lights. The south gable has been altered with 20th-century render. It contains cambered-headed windows: one to the attic, two to the first floor, and one to the ground floor. The east side has flat-roofed additions disguised by coped walls to the north and south.

A long corridor range extends northeast, with four similar pointed windows in the north wall, connecting to a monopitch-roofed annexe. The annexe has a north coped parapet and a central stone stack. The north wall incorporates iron-lattice lancet windows, similar to those on the porch. Two are on the first floor to the left, three to the ground floor to the left, and one to the ground floor to the right. The side walls have stepped coping. The roof is of grouted slates. The south front of the annexe has a window, a door, and a window to the left, and an altered pair of windows to the right. A link range behind the north wall has been entirely rebuilt in the 20th century.
