Englefield House and Entrance Courtyard Adjoining to North East

House. Constructed circa 1590-1600, with alterations in the early 18th century and again circa 1823-29 by Thomas Hooper. It was largely rebuilt circa 1850-60 by Richard Armstrong, and the long gallery was also rebuilt following a fire in 1886. The building is constructed of ashlar, flint and stone chequer-work in the plinth and beneath windows in bays, with some red brick to the rear. It has slate roofs. The design follows an H-plan, with towers located to the south-west and north-east. The house is three storeys high and features a moulded plinth, string courses, a pierced parapet with pinnacles and shields above the bays, arched corner turrets, and stacks with single and grouped octagonal shafts.

The south-east front displays mullioned and transomed windows with triangular pediments above the ground and first floor windows. It has five windows across the front, with a central full-height canted bay window and projecting flanking wings, each also featuring a full-height canted bay window and paired shell niches on their return fronts. The south-west front includes a canted bay to the right, a central four-stage tower with a second-stage oriel window and arched entrance underneath, and a lower brick wing with a battlemented parapet. The north-east front features a canted bay to the left, an enlarged four-stage tower off-centre to the left with a pierced parapet and corner turrets, a larger corner turret to the east with arched windows and flanking pilasters, arched top-stage windows, and large mullioned and transomed windows in the second and third stages. It also includes a triple-arched main entrance beneath an arched porte-cochère, a lower tower off-centre to the right, and a red brick wing with a battlemented parapet and a large four-centred carriage archway. Early 18th century wrought iron gates and an overthrow lead to the long gallery at the north.

The associated entrance courtyard to the north-east has a wall approximately 100 metres long, of varying heights, with an entrance to the north-east. It is constructed of snecked rock-faced stone with ashlar dressings, featuring arched balustrading and square intermediate and end piers with obelisk and globe finials. The interior is predominantly mid-19th century and includes a double-height entrance hall with three early 18th century Corinthian doorcases and a triple-arched gallery; an arcaded central corridor with an 18th century fireplace and a 19th century staircase; a library with 19th century panelling, fireplace, bookcases, pelments, a rich cornice, and a 19th century panelled plaster ceiling with 18th century bird medallions; and the long gallery to the north.
