Cledwyn Main Building

Simple stripped down Georgian modern style. 3 storeyed, 5 principal bays. Snecked rough grey masonry brought to courses, with ashlar dressings in Portland stone, including continuous sill band and string course emphasising upper floor. Moulded plinth, and simple parapet behind which is a hipped slate roof, laid on in-situ cast concrete. The facades are simple and well-disciplined. Entrance façade is articulated by a regular grid of fenestration – simple flush mullioned windows (5 light to ground and first floor, narrower 6-lights to second floor). Steel window detail (hopper opening lights to lower floors, pivoting casements above). Low relief emblems in roundels between the upper windows. Central entrance has broad architrave, enriched by charming low reliefs of agricultural scenes. Entrance is flanked by narrow windows with scrolled ironwork screens. Shallow step to entrance, with ashlar stone planters (probably original) to either side. Rear elevation is similarly arranged about a central entrance up steps with flanking plinths. 4-5-4-light mullioned windows flanking the doorway, and there is long triple-light stair window with ironwork balcony with coronet detail above it. Outer flat panelled doors, and glazed inner doors set back into lobby. Upper floor and basement storey balance each other by their lower storey height above and below the principle floors. Like the main elevation, there are emblems in low relief between the upper windows. Return elevation to north has continuous bands of mullioned windows (2-4-2 lights). Similar arrangement to south partially obscured by adjoining link building (which is not listed as it is not considered to meet the criteria for listing).

Simple plan with central entrance halls to front and rear, leading to circular marble-lined lobby. Staircase at rear, with streamlined art deco rails and terrazzo stairs. Art deco influence also in subtle step-moulded cornices. Axial corridors on each floor give access to teaching rooms.
