The Orangery at Plas Brondanw Gardens

The Orangery at Plas Brondanw Gardens is a rectangular two-storey building constructed from local rough-dressed rubble, topped with a hipped roof covered in small slates. It features feathered eaves with oversailing eaves courses and tiled ridges adorned with reconstituted stone urn finials. The symmetrical northeast front has three arched entrances with projecting keys and imposts, leading to recessed multi-pane French doors. Above these are three elliptical windows with recessed small-pane glazing, and a half-hipped slated dormer at the center of the roof contains an octagonal window with spoked glazing bars.

At the southwest rear, there is an external parapetted stair that leads to a first-floor boarded entrance, which has an oversailing parapet to the northwest. Below the stair is an open entrance and a square window. To the right of the stair on the ground floor is another arched entrance with a French door, similar to the others. Adjacent to the first-floor entrance is a flush lateral chimney with moulded capping, and beyond it is a narrow six-pane casement window. The southeast gable features an arched multi-pane window with a blind square window above, which has a fresco painting. The northwest gable is taller, and the ground slopes away from it towards the main road (A 4085), raising the ground floor on this side. Here, a French door opens onto a corbelled balcony with a simple iron balustrade.

In front of the orangery, a long flight of 16 slate steps descends in two stages to the lower garden level to the northeast, complemented by a plain wrought-iron handrail with urn finials.
