Large roughly square-plan house of 2 storeys and attics with gabled blocks and wings. Constructed of ashlar sandstone with a pecked surface under slate roofs with square stone stacks, mainly grouped. Detail includes raised copings to gables with kneelers and finials; 2-, 3- or 4-light mullioned windows with dripmoulds, most with transoms; quarry glazing. The entrance front faces E with garden front to S and 2 long wings to rear (N). East entrance front is of C19 fabric, but includes remodelling or refacing of earlier ranges, including single-storey hall to centre. At each end of the hall is a narrow advanced gable bay, single-storey with attic, that to the R incorporating the entrance. Entrance has a Tudor-arched head and decoration to spandrels; large square hoodmould, the corbels bearing heraldic motifs; double studded doors. Above is a stone tablet with heraldic shield and dated '1625'. Three-light mullioned window with hoodmould above doorway; similar windows to matching advanced gable to L. Between the gables the hall has a pair of 3-light windows. Wide gabled wings flanking, 2-storey and attic to L, 3-storey and attic to R, with long service wing adjoining. Behind the hall and alignedwith it is the roof of a higher range (stair-hall and landing), at the R end of which is a square tower. Wide adjoining gable to L has 4-light transomed windows (large to 1st floor library), and 2-light window to attic. Set back to its R (to L of staircase landing), is a high gabled dormer with 2-light window. The turret has a truncated pyramidal swept roof, a dentilled eaves cornice and supports a flagpole surrounded by iron brattishing; 3-light window to front. The wide R gabled wing is 2-window, all of 3 lights, with a single 2-light window to 3rd storey attic. Attached to the NE angle is a low 2-window range (originally a chapel). Two-light windows, not visible to lower storey; blocked round-headed doorway to S gable end, 3-light window to 1st floor and single light to attic. Set back behind is the long 3-storey 6-window kitchen wing. Narrow range against ground floor with short 2-light windows; 2-light windows to 1st floor and attic under gabled half-dormers. At the far R end of the kitchen wing is an added stills house, a single range at right angles and advanced. Raised ridge ventilator, 3-light transomed window to E gable end with planked door below. Single blocked light to attic, below which is a beam for supporting a hoist.
The garden front incorporates part of the C17 house along with evidence for its plan; recessed central block of the early C17, flanked by narrow gabled advanced wings also with fabric of this date, both flanked by C19 wings facing E and W. Three-bay central block is of coursed sandstone with central full-height canted bay under hipped roof. High moulded rubble plinth, 1st floor string course and moulded stone eaves cornice. Steep roof and large clustered red brick stack to rear pitch. Three-light transomed windows with ovolo-moulded mullions to each face of canted bay and to R bay, similar 4-light windows to L. Gabled attic dormers under hipped roofs with 2-light casements. The rubble plinth continues around the advanced gabled wing to L, and the masonry above appears older than the C19 work; 3-light window to each storey. Wing to R retains a fragment of the plinth, but is otherwise C19. Large 4-light transomed windows to ground and 1st floors; small 2-light window to attic; doorway to L return. To the R is the 2-window side of gable facing E, with 3-light transomed windows, large to 1st floor (library). To the far L, the side of the gable facing W is 1-window, with 3-light transomed window to ground, and 2-light windows above.
Broad gabled wing to W end of house (built in 1855), flanked by narrower gables set back. Wide 2-storey canted bay to centre; moulded cornice to ground floor, the 1st floor slightly set back, with dentilled cornice supporting decorative openwork parapets, each face bearing the letter 'M'. French doors to centre flanked by almost full-height windows; these and the 1st floor windows are cross-windows. Pair of 2-light windows to attic. Flanking gables have cross-windows to ground; 2-light windows above. N side of W end has cross-window to ground and 2-light window to attic. It adjoins the N gable end of an earlier wing (see S front), of rubble stone with plinth and quoins. Replaced 2-light mullioned window to attic; wooden cross-windows below. Short range (probably truncated) adjoining at right angles, of same materials, and with stepped roof, with replaced Tudor-arched doorway with studded door to R and 2-light window to upper L. The 3-storey 5-window nursery wing adjoins to the L and is slightly advanced. Small 2-light windows to ground; 3-light transomed windows above, under gabled attic half-dormers; R bay is wider with 3-light and 4-light windows to ground and 1st floor, respectively. To the N side of the house, the 2 rear wings enclose a courtyard, bound to the N by an unattached pre-C19 2-storey service range, of rubble stone with stacks, and mullioned or large-pane windows. The nursery wing has round-headed openings to ground floor, otherwise as elsewhere.
