Great Addington Manor House

This is a manor house, initially dating to the early 17th century, with subsequent alterations in the 18th century and enlargement during the mid-to-late 19th century for the Lane family. The building is constructed of squared coursed limestone with a Collyweston slate roof. Originally designed with an E-shaped plan, it now has a more complex layout. The main front features a seven-window range and a three-storey gabled porch with a four-centred arched doorway bearing a partially legible datestone indicating 1615. A three-light stone mullion window of 17th-century origin is located on the first floor above the doorway, with a matching window in the attic. Flanking the porch are two-light stone mullion windows, and the original 17th-century gabled wings project forward to the left and right. The ground and first floors have three-light stone mullion windows of 19th-century date, with transoms to the ground floor windows. Attic windows matching the 17th-century style are set in the apexes of the gables. Further 19th-century gables project prominently on the left and right sides, featuring six-light stone mullion windows, also with ground-floor transoms. A continuous hood mould runs over the ground and first-floor windows. The building is finished with ashlar gable parapets, kneelers, and ashlar stacks at the ridge and eaves.

To the left of the main front is a four-window range containing 19th-century stone mullion windows. A large, canted stone bay is present to the right, featuring a panelled frieze, and a moulded stone door surround is situated to the left. Attached at a right angle is a four-window range, likely dating to the 18th century, with the central two bays projecting slightly. This section has two-light stone mullion windows, a raised string course between floors, and an ashlar parapet with a moulded cornice. A 19th-century billiard room projects to the rear right of the main front; its gable features an inscribed tablet commemorating Viscountess Downe, the wife of Squire Lane. The rear elevation displays three 17th-century gables, some containing stone mullion windows, and a 19th-century extension in a similar style, originally used as domestic offices.

The interior entrance hall has 17th-century panelling, some of which has been re-used, and a fireplace with a moulded stone surround and a four-centre head. A staircase with a half landing features moulded splat balusters, some original 17th-century examples and others are later reproductions. Rear halls and reception rooms on either side of the entrance hall contain some 19th-century panelling and moulded stone fireplace surrounds, including Delft tiles and carved overmantles made from reset 17th-century panels. A 17th-century fireplace with a moulded stone surround is found in a first-floor bathroom to the right of the landing. First-floor fireplaces also incorporate reset 17th-century panelling as overmantles. Coved ceilings, which extend into the attic level, are a feature of the first-floor rooms. A winder staircase, with a 17th-century turned handrail, leads to the attic, located above the porch. The original range remains within the former kitchen of the 19th-century domestic offices at the rear, and a first-floor room at the rear was used as a coal store for servicing the bedrooms. Some of the original roof structure is still in place.
