The tower block is of 2 storeys with sunken cellar below and parapet above. Rectangular plan with a full-height semi-circular projecting stair turret to R of main face. Rubble construction with fine quality freestone and sandstone ashlar. Single large, depressed- arched window openings to ground and first floors of front and rear elevations with moulded reveals and simple returned labels. C19 cross-windows with leaded lights, the upper ground floor ones with good C19 heraldic glass. The stair turret has 3 chamfered slits and a pyramidal stone roof with C20 weather vane. Large projecting parapet at roof level with stepped machicolations, the corners off-set and carrying very fine carved stone gargoyles in the form of dragons and beasts. Cross-loops to parapet with splayed inner faces, 2 to the front, 4 to the rear and 7 to the sides. The roof is medium-pitched and of slate. Within the roof-space however, 2 previous roof structures are visible, the earliest, probably late C15/early C16 with very shallow-pitched, chamfered and stopped trusses testifying to a near-flat roof as expected. The upper window to the rear face has carved heads at the label stops, the costume-detail of which is correct for mid C15. Above the label is a contemporary carved shield bearing the arms of England quartering France modern, supported by a mermaid and a griffin. On the NE face (facing the main range) the roof-line of the former hall is visible where there is a contemporary moulded hood.
Adjoining the tower to the SW (L), stepped-down and slightly advanced, a square, 2-storey addition, probably a garderobe tower and of first-half C16 date. Rubble-built with dressed quoins. A parapetted gable to the L, shown on the Moses Griffith water-colour has gone, the front having been raised slightly during the C19 alterations and given a coped parapet. 2 small, splayed lights to each storey, one each facing front and rear. The main range adjoins the tower to the NE (R) and is stepped-down. Rubble-built with a medium-pitched slate roof behind an early C19 coped parapet, replacing a standard roof with gabled dormers. 4 bays with a division visible between the first 2. C17 chimneys flank the central bays, that to the R a projecting stepped and kneelered end- chimney. Both have been given off-set paired stacks with simply- moulded coping in the C19. C19 stepped entrance to L bay with stopped-chamfered Tudor arch, geometric spandrels and simple returned label. Above this a 2-light window with dividing transom. The 2 central bays have 6-light mullioned and transomed windows to ground floor with cross-windows above, both with segmental relieving arches visible above. 2-light mullioned windows to the 4th (right hand) bay. The parapet has a moulded string-course and capping, the latter stepped above square dormer lights at bays 1, 2 and 3. All windows are leaded. The bay to the far R (bay 4) is entirely of C19 date and terminates in a sloping stepped wall with decorative crenellations. This continues NW at a height of 10ft where it turns again at right angles to terminate about 60ft to the NE in a modern entrance.
The rear elevation is asymmetrical. 2 adjoining plain gabled wings with end chimneys. Near-flush casement windows, that to the L gable 2-part, leaded and with brick-cambered head. To the R gable, 3 windows: a late C19 French window with a 2-part C18 leaded casement above. Then, to the R a large 6-pane window. Plain square casement windows to upper gables. A further 2-part leaded casement to R infil between th gable and the tower. To the L and projecting infront a late C19 single-storey flat-roofed extension with parapet and 2 and 3- light mullioned windows. A modernised conservatory infills the space between this and the advanced tower.
Adjoining the main range to the NE, and partly screened by the sloping wall adjoining the main facade to the R, early C19 service extensions. Of brick with slate roofs. To the L a 2-storey range with projecting stepped end chimney to the R. This block is continuously-roofed with the NE pitch of the NE gable, the roof of which it extends. Multi-pane near-flush tripartite casements to both floors with cambered heads and projecting stone cills. 9-pane window above. Projecting outwards to the L a contemporary single-storey extension with window as before and extruded porch with hipped roof. Plain boarded door with plain fanlight. A further storeyed wing to the R of this, set back and with window as before to first floor. Cambered-headed entrance with boarded door and above a 6-pane window as before. Advanced modern extension infront of this with similar, though modern fenestation. Finally a single-storey range stepped-down to the R with a 3-pane cambered window. A modern covered walk-way adjoins to the front.
The listing excludes the modern cottage and outbuildings adjoining to the R.
