South Ferriby Hall

South Ferriby Hall is a small country house built in 1805 for Sir John Nelthorpe, with later 19th-century additions to the rear. The house is constructed of red brick, with the original section featuring a Flemish bond pattern, and the front and right return using narrower facing bricks. The central front section has a concrete tile roof, while the wings and rear have slate roofs.

The house is planned around a double-depth central section, containing a single room to the front with a pair of canted bays and an entrance/stairhall to the right, flanked by single-room projecting wings with canted fronts and later additions to the rear. The main rooms are positioned to the front and right, while service and servants' rooms are located to the left and rear. The building is two storeys high and six bays wide, exhibiting a symmetrical design with a four-bay central section flanked by single-bay wings.

The entrances to the end bays of the central section feature flights of four stone steps leading to half-glazed panelled doors (one of which is a dummy) under plain overlights, all within channelled and keyed stucco flat arches. A pair of full-height bay windows with three 12-pane sashes on each floor are centered on the front, set within Doric surrounds with columns supporting recessed entablatures. The first floor has similar 12-pane sashes to either side, again with channelled and keyed stucco flat arches and projecting cills. The wings' fronts each have three similar windows to each floor, with a blind window panel on the right side of the left wing. Three downpipes featuring fluted rainwater heads bearing the date are attached to the central section. The eaves have a plain board.

The central section has a double-span hipped roof, while the bays, wings, and additions have hipped roofs. Axial stacks are present on the front central section, a large axial stack at the rear, and lateral stacks on the wings and later section.

The right return has a two-storey section with an attic to the right, spanning five bays. The original wing on the left has three stone steps leading to a French window, and single 12-pane sashes to each floor, similar to the front. A later section set back to the right has three flush 12-pane ground floor sashes under segmental arches, a similar sash and a tripartite sash to the first floor, and two unequal sashes to the attic, finished with a stepped and cogged brick eaves cornice.

Inside, the stairhall features an open well staircase with a ramped and wreathed handrail, column newels, and balusters. The lower hall has an ornate dentilled cornice, and the upper hall features a modillioned cornice and a pair of round-headed doors with radial fanlights within architraves. The central ground floor room has a moulded dado rail, ornate moulded cornice, and a marble chimneypiece with a reeded surround and a frieze with carved panels. The ground floor right wing has an ornate moulded cornice and a marble chimneypiece with triple half-columns and a pulvinated frieze with carved central and side panels. The three main first floor rooms also have moulded and dentilled cornices, along with good chimneypieces featuring composition ornament, the one in the centre left being particularly ornate. Beaded-panel window shutters and doors are set within architraves throughout.
