[1] Located in the historic county of Westmorland, the house was designed by the Lancaster architects Paley and Austin, and was one of the earliest commissions of the partnership.

[2] The family moved out of the house shortly before World War II, and it was then used by Lancashire County Council as a school for children with special needs.

Sedgwick House is constructed in tooled sandstone, with ashlar and granite dressings, and has green slate roofs.

The entrance wing faces north, and has a projecting central four-storey battlemented tower, with a turret rising to a higher level.

The garden wing faces west, its outer bays projecting forward and containing two-storey canted bow windows.
