Former Admiralty Boat House

The Former Admiralty Boat House is a two-storey building constructed in 1901, designed by Thomas James and J S Tregenza, originally serving as a Coastguard boat house with a watch room.

It is built from two types of Cornish granite: Castle an Dinas rubble for the walls and Sheffield ashlar for the dressings, with a slate-covered roof and some cast iron rainwater goods. The exterior features a functional design enhanced with decorative details. The walls are made of snecked rubble with ashlar dressings around the openings, quoins, banding, and stacks. The principal elevation faces south and includes a wide entrance beneath a cambered arch, flanked by two timber sash windows on the first floor, which sit under a relieving arch. The gable end is coped and includes kneelers and a ventilator. The entrance is fitted with panelled timber doors, and to the left of the entrance, there is a postbox bearing the GR insignia.

The side elevations feature timber casements and sashes, with the first-floor casements at the south end having shouldered heads. The west side has a central chimney that is corbelled at the first-floor level. The north end elevation includes a ground floor door and twin sash windows with granite dressings and a relieving arch on the first floor.

Inside, the ground floor boat house was converted into a post office in the early 20th century, featuring a timber post office counter and timber wainscoting. There is a door leading to the first-floor stair in the north corner. The flooring varies, with some areas tiled and others laid in herringbone block, while a section at the rear has a concrete slab where a safe once stood. A lateral beam in the ceiling supports the base of the chimney in the west flank wall. The first floor contains the former watch room and store, now converted into offices, featuring early 20th-century joinery, including doors and cupboards.
