Lon Twyn

Lon Twyn is a large Arts and Crafts house dating to the early 20th century, set within a terraced garden. The walls are roughcast rendered with Portland stone dressings, including a rock-faced plinth. The steep-pitched roof is covered in Westmoreland slates laid in diminishing courses, featuring slightly swept overhanging eaves, large moulded kneelers, and narrow rendered stacks. All windows are mullioned with rectangular quarries within metal-framed casements.

The front elevation is characterised by a centre-left entrance bay flanked by two gabled bays and an end bay to the right. The gabled bay to the left has a five-light first-floor window above a flat-roofed, canted bay window. The entrance bay features a six-light first-floor window positioned close under the eaves, above a Tudor-arched doorway with a keyblock and stepped hoodmould, accessed by three semicircular steps. The gable to the right projects to form a two-storey bay window with five lights to each floor and one light in each return. The end bay to the right incorporates a three-light first-floor window and is blank below. A side garden elevation includes a three-bay, flat-roofed, glazed loggia with roughcast columns. Above the loggia is a three-light bedroom window and, to the left, a tall stack with tiled offsets in the angle of a projecting two-storey gabled bay, which has five-light windows to each floor. The rear elevation is dominated by a full-height Tudor-style canted bay staircase window with transoms and mullions. A service yard includes a double garage, all with rendered walls and slate coping.

The interior retains the original plan and fittings. A wide entrance hall leads to a rear staircase and a service passage to the right. Reception rooms open off the hall, with a large living room (referred to on the original plan as a 'lounge') situated on the west side of the house, offering views of the front and side garden and access to the loggia. Service rooms, the kitchen, and scullery are grouped around a side entrance at the end of the passage, with a back staircase leading to the first floor. Upstairs, the plan includes three main bedrooms, one with a private bathroom, a maid's room, a workroom, and a boxroom, along with a sluice, a WC, and a bathroom. Original two-panelled doors with brass fittings have been preserved throughout. Parquet flooring is present in the hall and dining room. The lounge features a low stone fireplace with a Tudor arch, and leads to a loggia that has been converted into a wholly glazed conservatory. The staircase is panelled and lit by a large, Elizabethan-style, multipane three-tiered window, complemented by a large gilded mirror that was an original fitting. The dining room fireplace features a marble surround with a polished wood surround. To the rear is a ‘butler's pantry’ retaining its original glazed cupboards. Upstairs, the airing cupboard and a bathroom retain their original copper heating pipes. The roof space is divided by brick walls, and the trusses include collars, ties, and queen posts with raking struts.
