Ebeneser Chapel house and Sunday school

Ebeneser Chapel house and Sunday school is a 2-storey building featuring a 3-window range, with an additional single window block at the right (north) end. The school rooms at the rear consist of a 2-bay rectangular block, with a single window wing that advances at the southeast corner. The chapel house is constructed from rubble masonry with widely slobbered mortar and slate dressings. It has a slate roof with a tiled ridge and copings, and rectangular yellow brick gable stacks with stressed caps. The main section has a 3-window range with openings offset to the right. The windows are slightly recessed hornless sashes with margin panes, and there is a central boarded door with a rectangular fanlight above. The ground floor openings have narrow slate lintels. The south gable return features a similarly detailed ground floor window towards the rear. The single window addition is set back slightly from the main part and has similarly detailed windows, but these are 6-pane horned sashes, with the first-floor window located in a gabled half dormer.

The schoolrooms at the rear of the chapel house have rendered elevations and a slate roof with projecting verges, along with rectangular yellow brick gable stacks. The windows are slightly recessed tall 12-pane horned sashes, and the entrance is through a square-headed doorway in the south wall. In front of the chapel house, the garden is enclosed by a low wall made of Penmaenmawr granite rubble with roughly dressed coping. There is a single gate in front of the doorway, featuring square granite piers with rendered caps. The gate has alternating short and tall vertical rails with spearhead finials and cross rails between the lock and bottom rails. A similarly detailed gateway between the chapel and chapel house wall contains wider double gates.
