Thornby Hall, Walls And 2 Gazebos Attached To North West

Thornby Hall is a country house dating from the late 17th century, which was remodelled in the early 20th century by Charles Mardaunt. The building is constructed of squared coursed lias and features stone-slate and early 20th-century plain-tile roofs. Originally likely designed in an E-plan, the structure is now more complex and consists of two storeys with an attic.

The garden front has a seven-window range, with the central three bays dating from the 19th and early 20th centuries, featuring four- and six-light stone-mullion windows with transoms. To the left, there is a six-panelled door beneath a four-centred arch with a moulded stone surround. The flanking bays are 17th-century gabled wings, which include large 20th-century sixteen-light stone-mullion canted bay windows on both the ground and first floors. The attic features 17th-century two-light stone-mullion windows with arch-headed lights. The far left and right bays are early 20th-century with stone-mullion windows. The roofs are hipped over the central three bays and gabled over the flanking wings, with ashlar gable parapets topped with ball finials and large stone stacks at the ridge and ends.

The left elevation has four bays of projecting gables, with a square stone bay to the left of centre and other windows being early 20th-century stone mullion windows. The three gables on the left may be from the 17th century. A lead rainwater head is dated 1925. The left elevation mainly consists of early 20th-century domestic offices, with one three-light stone mullion window at the first floor that may be 17th-century and features arch-headed lights.

The entrance front has a three-storey projecting porch with a moulded stone doorcase and ribbed and studded doors, with all stone mullion windows being early 20th-century. Attached walls on either side of the entrance front include gate openings, gatepiers, and two gazebos at the corners, all also from the early 20th century. The interior has not been inspected, but some rooms are noted to have decorative plaster ceilings, wood panelling, and moulded stone fireplace surrounds, likely dating from the early 20th century. The 17th-century house was significantly enlarged and remodelled in the early 20th century for the Wills family.
