Llys-y-Coed (also known as Ystrad Cottage)

This is a two-storey Regency house, originally built in the early 19th century with a T-shaped plan, now appearing as an L-shaped layout. The house is constructed with brick in an English Garden Wall Bond pattern, while the front elevations are finished with roughcast rendering, featuring stucco quoins and simple stucco surrounds to the windows. It has a hipped slate roof with projecting eaves and prominent central chimneys.

The main (garden) front is symmetrical, with three bays. It has large recessed sash windows with 12 panes on each floor in the outer bays. The ground floor windows have gently-cambered heads and retain their original unhorned sashes. The central bay is a full-height bow, with an original French window with 8 panes and marginal glazing, and two stone steps leading up. Above the French window is a 16-pane window. A small single-storey porch extension, dating from around 1900, extends from the western end, with a curved face returned onto the front facade and a curved, marginally-glazed sash window. The western side features a pedimented, arched entrance with a door consisting of six moulded and fielded panels, re-entrant corners, and a plain arched fanlight.

The eastern side has 12-pane windows on both floors, the first-floor window being blind. A two-bay addition, dating from around 1900 and flush with the eastern side, features plain cambered-headed sashes. A modern, part-glazed brick porch now serves as the primary rear entrance, accompanied by a pentise linking the porch to a modern garage addition. Further 12-pane sashes are found to the rear of the main block and on the western return of the rear projection.

Inside, an arched opening with a moulded archivolt leads into the hall, which features a polychromed tiled pavement from around 1900. Six-panel doors are present throughout the main rooms, with simple moulded architraves. A straight-flight staircase returns to create a long, balustraded landing on the first floor, with stick balusters, scrolled tread-ends, and a swept mahogany rail. The stairwell has a segmentally-vaulted ceiling with a moulded plaster cornice, and further round arches lead off the landing. The principal ground floor rooms have panelled shutters and reveals. The eastern room contains an original built-in oak cupboard-chest, consisting of a six-panel cupboard over an eight-drawer chest of drawers, both with original brass furniture, located in an alcove to the left of the fireplace. The central room features a fireplace from around 1900, with a three-panel Arts and Crafts foliate frieze, flanking fluted pilasters, a moulded shelf supported by four brackets. A winding pine stair is also present at the rear, with moulded nosings.
