County Hall

County Hall is a late 19th-century building constructed in a Hotel de Ville style. The west-facing elevation, which fronts onto the Promenade, is asymmetrical with three storeys and an attic, built of snecked rubble stone with vermiculated dressings, stock brick voussoirs, deep entablature and cornice bands, and cill bands. Buttresses define the ground floor centre. The mansard slate roof has a steep pitch and truncated chimney stacks, with dormers featuring steep overhanging roofs and casement windows, paired to the left. A three-bay section is advanced towards the right end, incorporating an additional storey and splayed angles to the second and third floors, alongside small cast-iron parapets. A corner feature also has a further storey and small cast-iron parapets. Sash windows, some paired, are present throughout, with an anthemion panelled cast-iron window box holder above the central bays. The basement is boarded up.

The Albert Place front is similar, with seven windows and three storeys plus attic, featuring a main entrance recessed at the centre to a basement level. Corbelled chimney breasts are positioned to the left and right. A central Gothic tripartite dormer is surmounted by an ornate pitched roof porch with bargeboards and brackets supported by tall columns with foliage capitals. Local quartz panels are incorporated into the ground floor windows. The left-hand side elevation is six windows wide and comprises four storeys with an attic and basement, exhibiting simpler detailing; chimney breasts at the end and centre function as pilaster strips. The rear elevation is irregular, with four and five-window, three-storey, attic and basement end blocks framing a one-storey and basement range featuring a splayed front.

The interior preserves a large entrance hall showcasing Gothic details in the staircase and lift shaft cage. The stairwell is illuminated by stained glass windows. The Cambrian Hall, formerly the dining room, extends five bays to the north, comprising an aisled space with arched trusses and ironwork spandrels bearing the QH monogram and a partially glazed roof. A three-bay Court Room is situated to the west, characterised by deep ribs supported at the dais end by paired columns. Wall panelling, dado rails, and acanthus cornices are found in the main rooms. Original ceramic sinks with breast taps remain in the ground floor toilets.
