Bryn Taff, 67 Cardiff Road

Bryn Taff is a large Domestic Revival style house of three storeys, built in Flemish bond red brick with slate roofs, enriched with half-timber facings and hanging tiles. The building displays considerable architectural complexity, combining a main house with an attached coach house and former service wing that has been substantially modified.

The main house has pitched roofs with open gables to front and rear on the right side, and a crosswing with open gable to the left overlooking the service wing. A distinctive slide projects down to the north corner at a shallower pitch from second floor level to the mezzanine. The attached coach house features a pitched roof with hayloft and open gable to the front, with shallower pitches to the sides. A valley roof between the main house and coach house is concealed by a parapet. Tall chimney stacks rise to the four corners of the main house, with a middle stack at the roof apex. Original plate glass sash windows with blind boxes are retained throughout.

The front elevation presents three bays. The right bay projects forward with a bay window at ground floor and a parapeted balcony to the first floor room above. A central porch in brick and timber features a pitched slate roof and open front gable with half-timbering. The left bay is recessed at first floor level with a monopitch slate roof in front. Clay hanging tiles with fish-scale bands decorate the open upper gable. The former coach house doors are now fixed timber with ribbon glazing. First floor windows are topped with shallow brick arches and drip moulds.

The right elevation shows projecting chimney breasts, with glazing restricted to the central bay. A rear right projection houses a dining room beneath a monopitch slate roof. A modern external fire escape staircase crosses the rear elevation, descending from the open upper gable via landings at first floor and mezzanine levels.

A mezzanine billiard room occupies the rear left corner, covering half of the original service wing and projecting to the rear of the building. The mezzanine front corners have hipped roofs, with two open gables projecting out on either side to the rear. A large central lantern with a pitched slate roof opens to the short sides. The mezzanine sides are faced in Tudor-style half-timbering with a lower brick band in common bond below windowsill height. The overhang rests on expressed horizontal steel joists supported by four Corinthian-styled steel columns set atop brick piers with middle banding.

A London-style blue plaque commemorating David Morgan was added to the front by his descendants in 2013.

The internal layout follows the plans published by Halliday and Anderson, with five bedrooms on the first floor and three servants' rooms above. A remarkable amount of late-Victorian detailing survives. The entrance hall contains a fine stone fireplace with a Tudor arch opening and mantle in the form of a crenellated parapet with a hipped roof. A central shield is engraved 'CS' for Charles Sankey, the first owner.

The dining room occupies the rear eastern corner and features square oak wall panelling with a central panel over the fireplace carved with the Morgan coat of arms—three boars' heads, a sword and five lozenges—and crest of a claw holding a severed hand. The motto 'Dyfalbarhad' (perseverance) is inscribed. A Tudor arch fireplace below has small shields at the corners bearing the initials 'DMB' and 'EWM'. A geometric tracery plaster ceiling decorates the room. Similar oak wainscoting, door frames and fireplace surrounds appear in the morning room in the front west corner, as well as in the drawing room, which also features panelled walls and a fireplace.

The mezzanine billiard room displays oak wainscoting and a fireplace surround, with lead-framed small-pane glazing incorporating stained panels bearing the initials of the Morgan family. The lantern contains stained glass incorporating a quotation from George Herbert (1593–1633): 'Play not for gain, but sport. Who plays for more than he can lose with pleasure stakes his heart.'

An oak staircase, interrupted by modern doors inserted on landings, descends to a wine cellar below. A double floor-height coal store extends beneath the ground floor at the rear north corner, with the coal chute still intact internally. Deep Tudor arch doorways lead to the two largest bedrooms on the first floor. The former coach house has been partitioned internally to accommodate a side boiler room. David Morgan's Turkish bath has been lost.
