Despite the mutilation of its S front (when the multi-gabled top was removed), the house is still an awe-inspiring pile. The S front and its E return are of ashlar, but the rest is all coursed rubble; with stone slate roofs to both parts. The plan is strictly rectangular, on an E-W axis facing S, over 25m long and 15m deep, divided axially by a spine wall incorporating 3 chimney stacks, plus a spiral stair at the W end. When first built both the front and rear elevations were 3½-storeyed and symmetrical, each with 4 gables, and with 3 chimney stacks rising from the valley between the roofs; and the E and W ends were twin-gabled.
The now-2-storeyed S front is 4-windowed, with string-courses linking the hoodmoulds of the windows. These are uniformly large and square, of 4 lights with a central transom, and the mullions ovolo-moulded. In the centre (slightly overlapping the windows to its right) is a 2-storey gabled porch in a florid but inaccurate Renaissance style - eloquent of the social ambitions of its builder and the artistic limitations of his mason. This has a moulded Tudor-arched doorway with (solecistic) imposts, framed by unorthodox pedestalled pairs of columns with an enriched entablature including prominent moulded cornices which carry round. Above this, the upper floor has (first) "a mantled and helmeted armorial shield with many quarterings, flanked by positively barbaric terms" (Pevsner & Newman), framed in similar fashion but on a reduced scale, including pairs of columns with shared capitals, apparently intended to be Ionic; then a transomed 3-light window, and above that a gable filled with a strapwork pattern.
The W elevation has a Tudor-arched doorway offset slightly left of centre (opening onto a lobby-entry to the main service rooms of the house), above which is a stack of four 2-light mullioned stairwindows and a 1-light window at the top (lighting a spiral staircase incorporated in the kitchen chimney stack). To right and left of these the gable-ends of the front and rear ranges each have mullioned windows of 4, 4 and 3 lights on successive floors, and the latter finishes with a 2-light attic window. As elsewhere, all these mullioned windows have hoodmoulds and ovolo-moulded mullions. Reflecting the superior status of the E end of the house, the E elevation, by contrast, has large 4-light transomed windows to the two main floors, a transomed 3-light window to the 2nd floor of the rear range and a 2-light attic window; while the rebuilt gable of the front range has a 3-light mullioned window to the 2nd floor. To the left of the main windows of the rear range are 1-light closet windows.
The rear is very regularly fenestrated, with 4 mullioned windows to each floor: of 4 lights to the first 2 levels, 3 to the third, and 2 to the attic gables. The only break in this regularity is a Tudor-arched back doorway immediately to left of the 3rd ground-floor window.
