Description
Ael y Bryn is a Regency villa that stands two storeys high and has three bays, with a roughly square layout. The exterior features pebble-dashed walls and a hipped roof made of graded slates, complemented by wide boarded eaves and two ridge stacks. The central entrance consists of a fielded-panel door topped by a two-pane margin-lit overlight. The windows are 12-pane hornless sashes. A hipped-roof veranda spans the lower storey and wraps around both sides of the villa, supported by wooden posts that feature pierced roundels in the spandrels of arched brackets. On the left side, there is a castellated wall with a Tudor-arched doorway and a boarded door. The right side wall includes two blind windows on the upper storey.
