Description

Alma House is a terrace of 4 late-Georgian style 3-storey houses located at 1-4 Alma Street. The buildings are constructed of scribed roughcast (with renewed render to No 1) on a painted freestone plinth, with hipped slate roofs and roughcast chimney stacks.

Nos 1-3 are 2-bay houses. Doors are positioned on the right side beneath round-headed overlights. No 1 retains its original door with round-headed panels, No 2 has a replacement marine-style door, and No 3 has an early 20th-century half-glazed panel door. On the left side are 12-pane hornless sash windows. Above these are 2-light oriel windows to the first-floor sitting rooms, centrally placed on No 1 but offset to the left side on Nos 2 and 3. The upper storey features 9-pane hornless sashes. Basement windows occupy the left-hand bay beneath 4-centred arches, with No 1 having a replacement window and Nos 2 and 3 retaining small-pane windows.

The 2-bay right end wall facing Castle Street has blind windows except for a 12-pane hornless sash to the right in the middle storey and a shorter 12-pane hornless sash above it. Set back further right is a 2-storey extension in similar style, featuring a half-glazed door and small-pane sash windows.

No 4 is larger, a 3-bay house with a wider advanced left-hand bay. It has a central panel door beneath a round-headed overlight. The outer bays contain 12-pane hornless sash windows in the lower and middle storeys. The upper storey has a 9-pane sash window to the right and a blocked left-hand window with painted glazing bars. Basement windows to the left and modern glazing replacing the coal-hole to the right are present. The 2-bay left end wall facing the sea has an added conservatory and replacement windows.

The interior is planned around a central entrance hall containing a full-height open-well stair with plain balusters and newels and panelled tread ends. Main rooms have panelled doors and polished slate fireplace surrounds in simple classical style.
