Plas Gogerddan

Plas Gogerddan is a country house, now in office use, dating from the late 17th century and substantially altered and enlarged in 1860. The building is constructed of painted stucco with slate roofs and 19th-century red and yellow brick chimneys featuring cornices.

The Main Structure

The original block forms an L-plan of two storeys with an attic, topped by a hipped roof with two chimneys on the eastern ridge and one on the rear south slope of the western wing. The main facade faces north, presenting a three-window front with broad short plate glass sashes featuring marginal panes set in moulded surrounds with vermiculated keystones. The first-floor windows have bracketed panelled sills. A large 20th-century dormer with a flat top breaks the eaves, replacing three earlier 19th-century brick dormers. The north facade also includes 19th-century stucco window surrounds, quoins and plinth.

The western return presents two windows with narrower plate glass sashes in similar surrounds; the ground-floor left window is blind. A gabled 19th-century brick dormer sits to the right. A short wing at right angles projects from the main block, its north front featuring a large 20th-century eaves-breaking dormer (replacing a 19th-century brick dormer) above a triplet of windows. These windows are paired with similar windows flanking the main door. The plate glass sashes are narrow to each side, with the first-floor centre sash broader and carrying a cornice on consoles. The broad door sits in a similar door case with matching cornice. Quoins mark the northwest corner.

The eastern elevation displays angle quoins and two broad canted full-height bays with canted hipped roofs flanking a broad central bay. The centre bay contains a 20th-century broad 4-light attic window breaking the eaves under a flat head, with 20th-century 4-light windows to each floor below, replacing two sashes per floor shown in an old photograph. The canted bays feature narrow plate glass sashes in similar surrounds. A sill band and plinth run across. The south end carries similar quoins and sill band, two broad plate glass sashes with marginal panes to each floor and a narrow plate-glass sash on the first floor centre. A 19th-century brick gabled dormer is present.

The rear of the entrance wing, set back to the left, displays three long first-floor 15-pane stair lights with similar surrounds and sill band, topped by a brick gabled dormer.

The 1860 Wing

The added 1860 wing comprises a long western part of two storeys with two parallel roofs, hipped at the western end. Its long north facade is broken by a gabled projection. A sill band runs throughout, with 12-pane horned sash windows in moulded surrounds featuring keystones. To the left, three widely spaced bays contain sash windows to each floor, with three narrow arched niches, one positioned to the left of each ground-floor window. The gabled projection displays quoins and two sashes per floor, the upper ones carrying cornices on consoles. To the right, the range is less regular: a long 18-pane stair-light breaks the sill-band to the left, followed by a pair of sashes per floor, then a blank window over an arched niche, and finally a sash per floor. Quoins mark the northwest angle.

The western end features a similar three-window range with a central door. The doorcase carries a cornice on consoles. Three brick stacks rise from the north ridge, one from the south ridge, and a glazed 19th-century square lantern with an oval glazed conical cap sits to the right, with an east-end brick stack also present.

The long south rear facade, of some eleven bays, contains sashes with a sill band.

Interior

The interior has been much modernised. The original block contained a drawing-room to the northeast, a dining-room to the southeast and a small room between. To the west lies an entrance hall giving access to a rear stair hall. This stair hall features an open-well stair of painted wood with a ramped rail, scrolled at the foot, with three balusters per tread turned in a column-on-vase pattern and scrolled tread ends.

The 1860 wing comprises a spine corridor with the kitchen to the south and servants' hall to the north in the gabled projection. A servants' stair with stick balusters serves this area. On the first floor south side, the billiard room features a panelled coved ceiling and a large glazed lantern. The lantern contains a row of 4-pane fixed lights to each side with a boarded ceiling around the oval conical light.
