Exterior
Extensive 2-storey country house of complex and irregular plan. The primary hall- house was extended to the W in the mid C18 at which period the S, park-facing elevation became the principal front. The whole was Gothicised in a Victorian encasing and various additions were made to the N and NW both then and in the early C20. Of limestone construction partly encapsulating a timber-framed, E-shaped core; slate roofs and plain end and central chimneys. The entrance front is to the E and contains the primary house. This has a storeyed and gabled porch with flanking 4-light wooden mullioned windows and advanced wings beyond, partly enclosing a medium-sized entrance court; plain late C19 sashes throughout. The porch has a rendered upper stage with 3-light window; C19 Tudor-arched entrance with panelled doors. Three-window R return with modern multi-pane French doors to the gable end. The L return has a re-used lead hopper to a C19 downpipe with the date 1764 and the initials I.M (for Colonel John Myddleton).
This left-hand advanced wing was probably originally a parlour wing and was converted into a full-height dining room in the C18. A balancing drawing room was placed on the other side of the stairwell thereby creating a new lengthened garden elevation to the S. This is near-symmetrical and has large, full-height canted bay windows to each end flanking a middle section with central gabled stairwell bay. The canted bays have plain-glazed cross-windows with arched lights and returned labels; crenellated stone parapets. The 2-storey central section has a pierced quatrefoil parapet, with 2 cross-windows to the L and a single cross-window to the R of the central bay; two 2-light windows each to the upper floor with early C20 blind boxes. The central bay has an entrance to the L with linenfold panelled garden door having pierced tracery upper lights. Above this is a large 4-light transmullioned stairlight with corbelled sill; this replaces an C18 Venetian window known to have occupied this position. In the gable apex is an heraldic cartouche within a moulded panel. On the L gable end is stone plaque with, in raised figures and letters:` I M M 1777 Restored 1882 O& AB; blind flanking cross-loops.
A long, mostly C19 N range extends as a parallel wing behind the S front, with a sunk topiary garden in between. This wing has paired sashes in shallow corbelled oriels to the upper floor with blind boxes as before. Arched-light cross-windows to the ground floor, one altered to form a modern multi-pane French window and to the R a large C20 bow window. This wing returns to the N to form a further, contemporary Z-plan range with similar windows and plain gables. The N side faces a large, irregular service court with walled garden divided off to the L, behind a C-shaped section with projecting gabled wings (that to the R, containing the 'Evidence Room', of brick). Three entrances to the central section, that to the middle with bracketed and gabled canopy, with decorative bargeboards and finial; boarded doors. That to the R faces E and is in the centre of a further projecting wing which has a storeyed extruded bay in its angle with the main range; single sashes and some small-pane casement windows, one, to the ground floor of the extruded bay, with arched head; bracketed canopy porch to the latter entrance.
Projecting northwards to the far R is a long, 6-bay, single-storey service block with 16-pane unhorned sashes and a C20 part-glazed entrance to the 4th bay. This returns to the E in a one-and-a-half-storey former coachhouse block. This has 2 C20 boarded garage doors with flanking boarded entrances and 3 12-pane sashes to the upper floor, breaking the eaves and contained within gabled dormers; pierced bargeboards and geometric finials. Deep verges with finial to the E gable.
Adjoining the NW wing (the right-hand advanced, L-shaped wing on the entrance front) is a high rubble wall which extends northwards for some 15m at a height of up to 3.5m. This has a 4-bay lean-to cart-house addition to its rear and has a wide, chamfered Tudor arch spanning the drive which leads around to the rear service court. The arch is late C19 and is surmounted by a crenellated parapet; further pedestrian arch to its L. The wall continues to the R for a short distance before terminating.
