Maes Glas, including railings & gate

Maes Glas is a late Georgian style terrace of 3 storeys with attic and 2-storey basement, located at 32-37 Castle Square. The building is constructed of Flemish-bonded brick with mainly graded slate roofs (replaced slate to No 32) sitting on a moulded wooden cornice. Small skylights and brick and roughcast stacks have been added. The terrace is built on a steep site.

The composition is distinctive. No 33 is brought forward under a pediment, has stucco walls, and comprises 3 symmetrical bays, providing the visual accent. The other houses are of 2 narrow bays each, creating an overall composition of 2+3+8 bays. The basements are single-storey of coursed rubble stone to the front, with windows mainly replaced in original openings. Elsewhere windows are hornless sashes with thin glazing bars and under wedge lintels. Upper storey windows are 9-pane; middle and lower storey windows are 12-pane.

No 33 has replaced lower-storey windows in original openings. A central entrance portico features tapering chamfered square columns on stone bases, with replaced double doors and a plain overlight. The pediment has a plain cornice and a round-headed attic window incorporating a 2-light casement.

The doorways to Nos 34-37 are on the left side and to No 32 on the right side. Each has a stucco doorcase with pilasters and consoles beneath a shallow hood, fielded-panel doors under round-headed radial glazed overlights. No 37 has an added porch; No 35 has glazing inserted into the middle and upper panels of its original door.

No 37 has a roughcast front and a coursed stone stack with corbelled cap dated 1911 to the right. A flat-roofed porch on the lower left has a 2-centred pointed arch in dressed surround with a boarded door and a pair of narrow lights in each side wall under shouldered lintels. The lower right window is set within an architrave and retains its original 12-pane hornless sash. In the middle storey are 2 oriel windows inserted in the late 19th century on cast iron brackets, with 4-pane sash windows under a hipped lead roof with swept eaves, carried on cast iron colonnettes. The upper storey retains original 9-pane hornless sash windows in architraves. The basement retains a small-pane sash window.

The right gable end of No 37 was rebuilt in 1911 in coursed dressed stone when adjoining houses were demolished. Two stone plaques, one in Welsh and one in English, are set into this wall and commemorate Baron Vaynol's gift of land for the investiture of the Prince of Wales in 1911. Each storey has a centrally placed 2-light mullioned window under a mould and incorporating 2-light casements. The windows have sill bands 2 courses thick of finely tooled stone.

The forecourt has cast iron railings with spear finials on a dwarf freestone wall. Gates to each cellar steps retain ironwork with lattice pattern in chinoiserie style (replaced to No 36 and with an added gate to the left side of No 33), but gates to the front doors are all replaced. The railings terminate at the right end (No 37) with a ramped return wall of coursed dressed stone abutting the house. Steps lead to cellars beneath the pavement.

The rear is roughcast with 4-pane sash windows. A single-storey wing is added at basement level.

Interior features include, in the entrance hall, a ceiling rose and moulded plaster cornice. A round arch with panelled soffit leads to the stair. A full-height open-well stair has a wreathed handrail, plain balusters, and moulded tread ends. The basement has straight flights of simpler stairs. The original panelled front door to No 37, retained inside the porch, has glazing inserted in its middle and upper panels.
