Description
Llys Menai 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. Each has a door under a round-headed overlight on the right side: 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 of each house are 12-pane hornless sash windows. The first floor features 2-light oriel windows to the sitting rooms, centrally placed on No 1 but offset to the left on Nos 2 and 3. The upper storey contains 9-pane hornless sashes. Basement windows are located in the left-hand bay beneath 4-centred arches; No 1 has a replacement window while Nos 2 and 3 have small-pane windows.
The 2-bay right end wall facing Castle Street has blind windows, except for a 12-pane hornless sash on the right in the middle storey and a shorter 12-pane hornless sash above it. Set back further to the right is a 2-storey extension in similar style, with 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 with 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 on the right and a blocked left-hand window with painted glazing bars. Basement windows to the left and those replacing the coal-hole to the right have modern glazing. The 2-bay left end wall, facing the sea, has an added conservatory and replacement windows.
