Haynes Park

Haynes Park is a country house with a complex building history, originally known as Hawnes. The house incorporates elements from various periods, replacing earlier structures. The west elevation was constructed around 1725 for Lord Carteret (later Earl Granville), likely by Thomas Ripley of the Board of Works. Around 1785-90, the south elevation was built for Henry Thynne, Baron Carteret, probably by James Lewis. Further work took place between 1849 and 1850 on the east elevation, commissioned by Rev. Lord John Thynne, Canon and Sub-dean of Westminster, and executed by Cubitts.

The west elevation is of red brick with flared headers and a later white brick parapet. The south and east elevations are white brick with ashlar dressings. All have slate roofs. The house is a square, quadrangular building of two storeys and attics, with 19th and 20th century additions to the north forming a second courtyard. The west front has a five-bay facade articulated by brick pilasters—four to the central bay and two to each outer bay—supporting rubbed brick moulded cornices. It features sash windows with glazing bars under gauged brick segmental heads. A doorway is located to the right of the central bay. The south elevation has a three-bay, seven-bay, three-bay arrangement of sash windows; the first-floor windows have glazing bars, while the ground-floor ones do not. Projecting outer bays contain two-storey bows. A recessed block is centred by four Portland stone Corinthian pilasters with paterae to the surmounting entablature and a balustraded parapet displaying the Carteret arms. The east elevation presents a ten-window range of sash windows and features an off-centre Greek Doric portico with paired columns, leading to double art-glazed doors in a moulded surround, topped by a balustraded parapet similar to the south front. The north elevation is plain, partially obscured by 20th century additions. A variety of ridge stacks are present.

The interior west wing contains an open-well oak staircase dating from around 1725. This features paired, fluted Tuscan column balusters, Corinthian newels, foliate carving to the open strings, and parquetry quarter-landings. The wing also retains some wood panelling and fielded panel doors. The south wing retains decorative features from around 1790 in the entrance hall and corridor, executed in a Neo-Classical style. The hall features high-relief plaster overdoors and oval plaster panels depicting female figures. The corridor, vaulted with rounded, half-domed ends, exhibits plasterwork decoration including vines, oak leaves, and squirrels. The east wing preserves marble fireplaces with Ionic columns.
