70, Wandsworth High Street Sw18

This is an early 18th century former brewery house, now offices, located on the north side of Wandsworth High Street. It was built around 1724 by bricklayer John Porter, with later alterations. The building is constructed of brown brick with a parapet and an M-profile tiled roof. It has three storeys and a basement, and a five-window bay facade with a central entrance and shorter windows in the attic. A grey brick band runs above the ground floor windows, while a continuous stone cill band sits below the first-floor windows; the attic windows have individual cills. A moulded cornice sits below the parapet. The windows have later sash windows with horns, set within recessed openings with gauged brick arches and dressings. The entrance features rusticated grey brick jambs and a 20th century wooden hood. The rear elevation is plainer, with an inserted attic-level door and links to a later, less significant rear wing and the associated brewery buildings.

The main ground floor room contains two imported plaster medallions dating from around 1730-40, depicting portrait busts of Inigo Jones and Andreas Palladio within ornamental surrounds. A full-height staircase has an open string, column balusters, and newels, with dado panelling. On the first floor, a room to the west features an 18th century marble fireplace with scrolled brackets and a full cornice. The central room is fully panelled with a deep cornice. There are several raised six-panel doors with deep architraves and L-strap hinges.

The building was originally built for John Porter, possibly as a brewer's house for the Drapers who brewed on the site in the 18th century. The plaster medallions are said to have been moved from a larger house in Wimbledon and were likely executed by Italian craftsmen working in London in the early 18th century. The house served as a brewer's residence until the brewery was sold in the mid-18th century. It was subsequently sold to Young & Bainbridge in 1831 and has been used as offices in the 20th century.

A stone-capped forecourt wall with a wrought iron gate is a notable subsidiary feature.

The building is listed for its early 18th century architecture, the substantially intact high-quality interior (including a fully panelled room, a full-height staircase, and the imported plaster medallions), and its historical significance as the oldest surviving part of the Ram Brewery. It possesses group value with the other listed components of the site: the Grade II* Brewery, the Grade II stables, and the Grade II Brewery Tap.
