Large Jacobean house of three stories above a basement; of square plan with recessed entrance bay to the main front and with large extruded corner towers carried up above the main roof line. The house is of local freestone construction with sandstone dressings on a chamfered plinth, and has ashlar faces to the NE (entrance) and SE (former garden) facades; slate roofs with large, plain central stacks. The corner towers have lead ogee roofs and surmounting wooden cupolas (restored), with corbelled eaves and small corner chimneys. The main (entrance) facade is symmetrical with its recessed entrance bay accessed via a flight of steps and crowned by a swan neck pediment. To the centre is an architectural entrance surround with a similar surmounting pediment and moulded entablature; both are restorations of the 1820s. The entrance has C19 double wooden doors and is flanked by tall, elegant cross windows; above is a pair of 6-light mullioned and transomed windows, reduced from 8 lights each in the C19. The third floor has an 8-light window as before, though with a contemporary moulded label; all the third floor windows on the main and rear facades, and all windows on the garden facade also have such labels. The flanking bays have shaped gables with small elliptical oculi, and are surmounted by decorative stone finials. The ground and first floors have 4-light mullioned and transomed windows as before, with cross-windows to the second; further cross windows to each stage and face of the corner towers, with oculi to the top, as before, and simple 2-light mullioned windows to the basement. Moulded stringcourses run continuously across the main facade between the floors and are returned onto the sides where they stop. Cross-windows with labels to the 5-bay garden facade, with a 4-light window to the third floor, a C19 reduction of a former transomed window; as with the other sides, the gable storey has been rebuilt, here in the form of a plain gable. Further basement windows as before and to the far L a primary garden entrance; this has an ovolo-moulded, square-headed opening with moulded label. Flanking this is a pair of decorative lights, that to the L in the form of a stylised I (for Iohannes) and that to the R in the form of a T (for Trevor). The returns of the corner towers to this side also have similar lights. The R tower has a further primary entrance: this has a moulded Tudor arch with moulded label-course returning to continue as a high plinth moulding to the tower; 2-light basement window to the R. Triple-gable rear (plain gables) with traces of limewashed render visible on its rubble face. There are paired 4-light mullioned and transomed windows to the ground and first floors, the former modern replacements, the latter reduced to 3-lights in the C19. 3-light mullioned and transomed windows flank these, with a further, similar window to the ground floor at L. 3-light windows to the second floor, together with 4 small (blocked) garderobe or closet lights, with shaped heads. The right-hand bay has (curiously) 2-light windows to the ground and second floors, rather than three. Asymmetrical openings to the NW (service) facade, with original off-centre, stopped-chamfered, Tudor-arched entrance. This has a 4-part overlight and is contained within the plinth moulding which steps up to include it. To the R is a 2-light window which served the original secondary stair; associated with this are further single-light and 2-light windows which punctuate the left side of the facade, following the stair's original course; the single-light windows are now blind, having been blocked up in the C19. Two 6-light windows to the R (now blocked) once served the kitchen and are replaced by a tall oak cross-window (modern). Further blind and open mullioned and transomed windows to the upper floors, including a reduced second-floor window and further blind garderobe lights. Adjoining the service (NW) facade to the N (R) is a low, single-storey late C18 service addition; of rubble construction with shallow slate roof, unglazed openings. This range has recently been re-roofed (c1990) and was formerly ruinous.
