3 Fron Dirion Terrace

3 Fron Dirion Terrace is a late Georgian building with Greek Revival influences, featuring two storeys and modern attics. The front has two windows and is rendered, with large panelled pilasters that have heavily ornamented capitals and an entablature decorated with floral dentils and stucco wreaths. The building has a slate roof and rendered chimney stacks, with arched headed panels on the end stacks. The left gable end has wide eaves, while the right gable end features an arched headed window and pilasters that project at both ends.

Numbers 2 and 3 have bay windows; the bay window at No 2 is squared and has similar ornamentation to the first-floor cill band, while No 3 has a modern, splayed bay window. It is possible that a bay window was removed from No 1. The entrances have cross frame windows above them, with No 2 having three-light windows, and Nos 1 and 3 featuring modern casement glazing.

No 3 has a doorcase with a pedimented and stucco decorated lintel, along with an arched panelled door. The window above this door, as well as the window at No 2, shares similar decorative details. The rear of Nos 1 and 2 has been modernised, while No 3 has an extension with sash windows.

Inside No 2, the first-floor drawing room retains arched niches and an elaborate deep cornice with interlace decoration. The cornice above the bay window has been removed, possibly to accommodate a Victorian pelmet.
