The scheme is linked and focused upon the cathedral like central tower. Henry Hare’s 1911 sections in buff coloured Cefn stone in snecked courses with freestone dressings and flat buttresses; slate roofs with parapet and stone chimney stacks. Mullioned and transomed windows with leaded lights.
Starting at the northwest Prichard-Jones Hall range facing College Road. 2-storey, 6-window front with advanced end pavilions. Steep roof, crenelated parapet and bellcote with lantern and spirelet. Tall segmental headed hall windows, double-transomed and with panel tracery; projecting flat roof ground floor with entrances to either end, deeply recessed doors. Left hand end pavilion had central stepped buttress flanked to 2nd floor by 2 segmental headed windows with unusual tear-drop oculi; right hand pavilion is lower with dentil cornice over 3-light window.
The original main entrance is on the SW gable end of this range. Broad gable with Tudor octagonal end turrets and Baroque niches containing statue of Lewis Morris to apex.

Advanced below is a triple arched porch with panelled pilasters, coasts of arms and Latin inscription dated 1911. Enriched spandrels over recessed entrances with double doors and lugged architraves to each. Shaped gables at right angles to either side, to the advanced end bays of the adjoining ranges; commemorative tablets with garlanded borders below each gable. At the top of the steps up to the entrance are cast-iron square, tapered lamp standards with bracketed octagonal lamps and openwork ornament.
The spinal/administrative range, together with the 1911 Library wing, forms an ‘L’ plan group to the E side of the larger SW quadrangle. The former has an 8-bay, 2-storey front, the advanced left hand bay as above, parapet is balustraded over cross frame windows with architraves to 1st floor and semicircular pediments to ground floor. Baroque entrance to centre with small-pane circular window over door.

The 1911 Library wing at right angles has a 9-window front with central royal coat of arms; 2 bays are advanced with tall 1st floor oriel windows. Crenelated parapet and gabled and panelled buttress pilasters. Arched headed lights, square headed 1st floor windows and segmental headed ground floor windows and entrance which has open pedimented doorcase, lugged architrave and double doors.

Attic to the advanced and gabled end bay with Baroque scrolls over stepped buttresses; 2nd floor has statue of Bishop Morgan flanked by cross frame windows under overall label. Symmetrical to right with a repeat of the courtyard elevation as above with the addition of a slightly swept out ground floor with single light windows and entrances below the oriels; 1st floor windows set in splayed recesses. Forward to right beyond the tower is the SE range of the NE courtyard. This has a gabled SW end with slate hung attic to left and chimney breast to right, the latter with open-pedimented tablet. 2-storey porch facing Penrallt road entrance with part balustraded parapet, tapered buttresses on chamfered corners and round arched entry with multi-pane fanlight - swagged shield over.
The main 3-storey and attic SE elevation is symmetrical with an especially collegiate feel to it. Tapered cross range gable ends advanced at the end advanced at the end of 10-bay range, the ground floor of which is arcaded and the central 4 bays open, forming a loggia; storey chimney stacks and flat roof attics over parapet. 2nd floor cornice extend to edges of end pavilions over shield; splayed broad buttresses.

Dividing pilasters to remaining bays. Segmental headed entrance to NW end bay and a smaller one lower down. Octagonal bellcote. The gabled NW return elevation is partly screened by the broader gable end of the hall range, which has a stronger Arts and Crafts feel to it - 4-light gable window, crenelated broad end pilasters with narrow lights and grills to lower windows.
The enclosed smaller NE courtyard is terraced with similar detail to that on the exterior of each range. The Hall range is at the top and has an ivy clad ground floor projection. The inner side of the SE range is symmetrical; lower gabled projection with polygonal corner turrets, lateral chimney breasts and frontis-piece with 3-light transomed window over scrolled inscription and round arched entrance. Six 2nd floor and three 1st floor segmental headed windows to either side; projecting ground floor. To SW the range is dominated by the tower’s 6-storey NE face; including splayed oriel with crenelated parapet and recessed plain Venetian window; lowest stage splayed out. Twin gabled 3-storey block projects to right of the tower matching similar projection opposite (NE range). The 4-tier terrace has rubble walls, freestone copings and ball finials, and central abstract steel sculpture on rusticated concrete plinth entitled ‘The Genesis’ by John Robinson, installed 1993 donated by Harwin Components Ltd, Ynyswen, Treorchy.
The 1963 Library extension is at a right angle to the 1911 Library wing, the two connected by a two storey glazed link, and forms the long SW side of the larger SW quadrangle. Wide and shallow flat roofed Modernist cuboid with two storeys facing the quadrangle and an additional basement level facing Penrallt road. Concrete frame clad in local slate stone blocks in a variety of shades laid in snecked courses to match the Henry Hare scheme, with plain concrete entablature of frieze and slight cornice. Steel framed windows with massive horizontal glazed rectangle to upper two floors on both long sides with 6 lights to upper floor and 4 lights below separated vertically by 24 triangular prism concrete mullions (plus half mullions at far ends) and horizontally by light terrazzo square panels. Main entrance on far left of inner elevation is sheltered by cantilevered concrete slab portico, with panel window above letterboxed by dark terrazzo. Penrallt road elevation has six two-pane horizontal windows to basement level widely spaced in the slate stone plinth and to far right glazing over three floors divided by terrazzo panels in different shades.
A shorter square two storey block in the same materials to the northwest end (connected by short concrete link section) was also built 1963 and used as plinth for one end of the 1968 extension, which begins at right angle to the Library, completes the main quadrangle by closing off the northwest side, with return towards southeast to join with gable end of entrance block in front of Pritchard Jones Hall. This is Brutalist with an expressed bush hammered concrete frame, steel-framed glazing and a trapezoidal felt roof. Four storeys in height, but across most of the northwest range the upper three storeys are held up on thin pilotis allowing pedestrian and vehicle access into the quad. Towards north corner a snecked slatestone curtain wall with upper section of concrete panels resumes to ground level, with a curved rear wall (to lecture room) projecting into the underpass continuing into projecting sloping dividing wall between the underpass and the north corner reception block. North corner block completing the northeast range is heavily glazed to ground floor housing main entrance and reception. Overhanging upper two floors with cantilevers on all three outward facing sides use tall vertical windows separated by double floor height concrete mullions. Dormers and small balconies to top floor. NE link section joining the Brutalist corner block to Pritchard Jones Hall more restrained with ribbon windows to first and second floors on both sides.
