Description
Plas Teg and Plas-yn-Acre
This pair consists of a large Georgian townhouse that was originally a single dwelling, formerly called Plas-yn-Acre. The building was probably divided into two separate residences during the second quarter of the 19th century, at which time the window openings were modernised and entrances were created on the side elevations. Plas-yn-Acre has undergone modernisation within the last few years.
The two houses form a reflected pair, each occupying two bays of the four-bay front elevation. They are two-and-a-half storeys tall, constructed of rubble stone and roofed with a high hipped slate roof. Tall panelled chimneys rise at the centre and sides.
The front elevation is symmetrical. Plas Teg retains unhorned original sash windows with fine glazing bars, whilst Plas-yn-Acre's windows have recently been replaced with out-of-character PVCu tilting copies. The ground floor central bays feature wooden canted bay windows with 20-pane main sections and 10-pane side sections. The outer ground floor windows contain 20 panes each, whilst the first floor windows have 16 panes. The upper floor windows contain 9 panes and are set within large finialled gabled dormers with deep verges and moulded bargeboards.
Side entrances serve both properties, each with a panelled door and reveals, sheltered by open flat-roofed porches carried on plain wooden pilasters. The rear elevation is whitened and features a similar upper floor window arrangement. Plas-yn-Acre has an additional modern first-floor entrance with a part-glazed door and metal fire escape.
Plas Teg has a later single-storey lean-to extension with a part-glazed door and flanking 6-pane windows, and a modern wooden conservatory extension to the left.
The entrance hall contains a segmental arch, with doorways off fitted with Regency-style moulded architraves and 6-panel doors. At the end stands a Regency full-height narrow well stair rising to the second floor, featuring a scrolled oak rail, stick balusters, and scrolled tread ends.
