Gwynfryn

Gwynfryn is a house, comprising the main part now known as No 16 and a service wing, No 17. The house dates to the 18th century and is constructed of rock-faced coursed Pennant stone with extensive Bath stone dressings and some half-timbering. It has slate roofs with red terracotta ridges and red brick chimneys. The facade is complex and asymmetrical, exhibiting a general Northern Renaissance style. The main part is two storeys and attic, with a recessed centre attic set between two coped gabled bays, the left bay projecting further than the right. The right gable exhibits a curved head, ogee curved sides, and corniced shoulders, while the left gable is straight-sided with a corniced shoulder to the right and a ball finial. The short left side abuts the slated spire of a large octagonal corner bay-window.

Ashlar ovolo-moulded mullion windows have sashes, with small panes only in the top sash. The right gable features a projecting two-storey square bay with a parapet stepped up at the centre and angles. It has a four-light window on each floor, with the ground floor window being longer. An ashlar chamfered plinth sits below the ground floor sill. Narrow windows are in the gable apex, set in flush surrounds.

The centre of the facade is recessed and contains a two-bay Bath stone arcade between the corner of the left gable and the corner of the right bay window. This arcade has a panelled centre pier and outer responds, moulded capitals, and roll-moulded arches with spandrel panels. A balustrade sits above the arcade, featuring turned stone balusters and a centre panelled pier, with mouldings continuing from the bays on either side. The ground floor has a moulded cambered-headed door and a plate glass window. Door mouldings stop at window sill height, each accompanied by an ashlar two-light overlight with leaded coloured glass. A six-panel door provides entry. The first floor has a triple mullion opening, serving as a door and two sashes, sheltered by a lean-to slate roof carried on a single, broad elliptical arch. Above this lean-to roof is a large half-timbered attic gable with a five-light timber window incorporating casements and small-paned top lights. The gable features vertical timbering, modillioned bargeboards and a terracotta finial.

The left gable has a small attic sash with a moulded course above, and a two-light window offset to the right above a canted ashlar bay with a moulded cornice and parapet with moulded coping. This bay is paired with the ground floor of the octagonal corner turret, which shares similar detailing. The turret has windows on five sides, with matching ashlar first floor details, including moulded string courses between floors, and a band of half-timbering under a candle-snuffer bellcast octagonal slate spire topped with a ball finial.

The left side of the house is plainer, featuring the octagonal bay to the right and a large projecting gable to the left. It is constructed of rock-faced stone with flush ashlar dressings, a raised plinth, and sashes with small-paned top sashes. The gable has an attic sash, a pair to the first floor centre, another to the right, and a long triple window to the ground floor. Between the gable and the corner octagon is a large lean-to with two small lights and a hipped slate roof.
