Interior
In spite of institutional use, much of the rich interior fitting survives. Plan is of a large central reception hall and formal staircase with corridor to rear off which lead the main reception rooms facing front and side, with acces to a rear service corridor. Many rooms have decorative plasterwork, large ornate fireplaces and dark stained heavily moulded woodwork; door surrounds have reed mouldings and friezes, 6-panelled doors, some enriched with carved panels; outer doors are chunky variants of the plank and batten type, some in grid form, with full width iron hinges; service hatches to rooms also moulded with quatrefoils and linenfold, decorative hinges; plentiful stained glass mostly depicting naturalistic flowers and birds.
Entrance lobby is very richly decorated, with stained glass to the main window and opposite a wide basket-arched screen incorporating 22 separate lights glazed with stained glass - the two at centre, the entrance doorway, replaced; archways are moulded and there is a carved tympanum to both inner and outer faces of the main entrance doorway. Main entrance hall has a pointed-arched 3-bay arcade to stairs enriched with ballflower and face stops, marble columns, coffered ceiling with friezes below. Richly moulded open well Jacobean-style staircase rises through central arch, elaborate newel posts incorporate griffins holding shields with monograms, gothic moulding to balusters, staircase wall of deeply moulded small panels; boarded ceiling with reeded joists, corbels in the form of grotesques, strapwork frieze; fine stained glass staircase window with floral motifs. Room at tower end has Neo-classical style white marble fireplace with egg and dart motif and lions with drapes, very deep ceiling frieze of Adam-style motifs with vine moulding to the cornice, coffered ceiling with metal roses/ventilators; arched recesses to tower with beast stops to hoodmould and pineapple and vine mouldings. On the other side of the hall the reception room now a music room has a coffered plaster ceiling, large fireplace with deep hood with Welsh inscription in Gothic lettering and ogee arch. Similar smaller fireplace with deep hood and ogee arch to other reception room. At end of corridor to side of second staircse is a room with beamed ceiling supported on corbels; huge Tudor-arched fireplace with deep hood enriched with bands of moulding, shallow niches to sides; narrow tiles to fireplace floor in green and black and to back in a chevron pattern of red, orange and green; dado.
