River House and Attached Area Walls and Railings

River House, originally the Yorkshire Club, is a building with attached area walls and railings dating to 1868. It was designed by C.J. Parnell for The Yorkshire Club. The building is constructed of red brick in Flemish bond, with stone dressings, bands, and quoins; granite columns are used for the porch. The roof is slate, with clustered polygonal stacks.

The building has a basement, two storeys, and attics. The central three-bay range is flanked by one-bay cross-wings, each featuring full-height square bay windows topped with shaped gables. A one-storey tetrastyle portico links the cross-wings and projects centrally as a one-bay porch, approached by steps. This portico is arcaded with squat columns, semicircular keyed arches, enriched hoodmoulds, and low-relief carvings of strapwork and York roses. The central doorcase features squat, tapered pilasters and a triple banded round arch with elongated keyblocks, leading to double glazed and panelled doors flanked by narrow sashes, beneath a semicircular fanlight. The window originally flanking the door on the right has been altered to a glazed and panelled second door. Columns and pilasters have foliate capitals. In the cross-wings, ground and first floor windows are tripartite sashes, while attic windows are single sashes. The centre range features a tripartite window between single sashes; the attic windows are pedimented dormers with keyblocks and finials. All windows have flush quoined surrounds, sloped moulded sills, and moulded cornice hoods. The building has moulded first floor and eaves bands, a coved eaves cornice below a pierced parapet with square section piers and tapered obelisk finials. A first-floor balcony above the portico has a similar parapet.

The right return has a four-bay front, with outer bays projecting as full-height canted bay windows. Basement windows are sashes, ground floor windows are French doors with transoms, and first floor windows are single sashes, with pedimented dormers to the attic. The detailing matches that of the front elevation. A terrace is located at the front of the ground floor, supported by cast-iron columns with waterleaf capitals. The interior was not inspected at the time of listing.

The attached area walls are low, pierced by roundels, with moulded coping and piers topped with tall finials of clustered volutes. Horizontal railings with a serrated upper edge are set diagonally between standards of paired volutes with ball finials.
