Manor House Upper Manor

Manor House, now divided into two dwellings, is located on Station Road in Irthlingborough. It dates from the mid-17th century and has been partially remodeled in the late 18th to mid-19th centuries, with further alterations in the late 19th century. The building is constructed of squared coursed limestone and features a 20th-century plain tile roof. It has an H-plan layout and stands two storeys tall with an attic.

The main front consists of four bays, with the end two bays projecting forward as gabled cross wings. The central section has a two-window range of two-light stone mullion windows, which were renewed in the late 19th century. To the left gable, there is a large 19th-century six-light canted stone bay window on both the ground and first floors. Each gable has a three-light stone mullion window in the attic. An oval plaque is set into the return wall of the left gable. The central door is of 20th-century design and features a moulded stone surround with a four-centred head. The gables have ashlar parapets and kneelers, along with ashlar stacks that have cornices at the ridge and ends.

To the right of the main front, the garden front has a three-window range of late 18th to early 19th-century tall sash windows with glazing bars and plain ashlar surrounds. There is a panelled door to the right of centre, which has a reeded wood surround adorned with lion heads, and an oval plaque above it. The left elevation of the main front features a three-window range of irregularly spaced three-light stone mullion windows, with a central door that has a moulded stone surround. The rear elevation has some 20th-century extensions.

Inside, the Manor House contains four and six-panelled doors with reeded surrounds and lion heads, and the window surrounds are similarly detailed with panelled reveals. The staircase, which is around an open well, has a stick balustrade and a rib-vaulted ceiling. The attic room includes one 17th-century panelled door, and the original roof trusses remain intact. The Upper Manor, which was not inspected, is noted to have a staircase with some 17th-century turned balusters.
