Brook Hall With Archway And School Sergeant'S Lodge

Brook Hall, an archway, and a School Sergeant’s Lodge were built in 1915, with later 20th-century additions, for Charterhouse School. The building is constructed of bargate rubble, finished with ashlar dressings, and has a plain tile roof. It is two storeys high and comprises eight bays. Five bays form Brook Hall, with an archway to their left and the School Sergeant’s Lodge above the archway and occupying the two bays to the left. The design is in an Elizabethan style, featuring a roll-moulded ashlar plinth, quoins, a string below a roll-moulded, embattled, ashlar parapet. The windows are mullioned and transomed, with cusped-headed lights; the lodge features quoined surrounds and diamond leading, while Brook Hall has diamond-patterned glazing bars. Brook Hall includes a two-storey porch to its second bay, with a panelled door, decorative hinges in a pointed-arched surround, a moulded string, and a broached canted bay window with a central three-light window. A tall double-transomed stair window is positioned to the left of the porch. The archway bay has full-height offset buttresses, a hollow-moulded three-centred arch with blind quatrefoils and cusped panels to the head, and a cornice with head and foliage stops. Above the archway is a four-light oriel, with three panels either side, the central panels glazed, set on a band of ogee-headed panels with heraldic shields. To the left of the main arch is a pedestrian archway with a single-light window on the left side. The roof has raised verges with roll-moulded coping. Ashlar stacks are present, one at the left end with an offset and cornice, and two rising from the rear, the one near the archway being an octagonal flue. A later 20th-century addition to the left, consisting of a single-storey structure with an attic and two bays, incorporates a garage door, a two-light window, and a dormer. The rear of the building features two-storey canted bay windows either side of the archway, a three-light window above the archway and a single-light window above the pedestrian archway. An external stack is visible on Brook Hall, and later 20th-century additions projecting on the right and left are not of special interest. The interior of Brook Hall contains a closed string, open-well staircase with turned balusters, leading to a richly decorated first-floor room. This room features panelling, a modillion cornice, a segmental-arched vault with plaster decoration, and a Tudor-arched fireplace with a pulvinated mantlepiece, richly decorated in Elizabethan style with fluted pilasters, round-arched panels, and a console bracketed decorative frieze. The archway into the oriel has a cusped panelled ashlar soffit. Two panelled doors are located at the left end of the archway, enclosed in architraves with fluted pilasters, triglyphs, finials and strapwork above.
