Sunday School Range

The Sunday School Range is a fine 2-storey classical chapel built with a 4-bay front featuring scribed render. It has a hipped slate roof with ventilators, a moulded eaves cornice, rusticated quoins, and impost and cill bands. The gallery windows are round arched with hood moulds and keystones, and they have coloured glass fanlights above small pane sash windows with marginal glazing bars. The lower windows are similar, set within pedimented architraves.

At the center, there is a flush frame portico supported by two Ionic columns with entasis, along with a cornice, entablature, and end pilasters. The portico features three round arched doorways with keystones and capitals, leading to 12-panel double doors. The side elevations have four windows, and at the rear, originally semi-octagonal, there is a projecting organ chamber.

To the left at the front is a small vestry and a passage leading to the Sunday School building, which is at right angles. Both have tall hipped slate roofs and scribed render elevations, with the smaller range featuring three pointed windows. The Sunday School range has a five-window side facing the chapel, with segmental headed small pane sash windows. Its 4-bay front includes round arched end entrances flanking central windows similar to those on the chapel. A square belfry with a pyramidal roof and ironwork finial is present, along with a broad gable end to the east that contains four windows under an overall band. There is also a low toilet block attached to the north side, featuring original Victorian fittings from Barrhead.

Inside, the chapel has a classical galleried interior with fluted and gilded columns topped with Corinthian capitals. The gallery front is panelled and has advanced aedicules. The ceiling features a coved cornice and a herringbone boarded band with roses, while triangular panels project into the central ceiling area, which is adorned with large octofoil roses. Ionic fluted pilasters support the segmental arch of the organ chamber opening. There are balustraded steps leading up to the platform and a panelled boundary for the 'set canu', along with brass wall brackets for lamps.
