The earliest part of the building is a tower of fourteenth or fifteenth century date. There are
oak-panelled interiors, including the Inlaid Chamber, where the panelling is inlaid with floral and geometric patterns in pale poplar and dark
bog-oak. The contents of the Inlaid Chamber were sold to the
Victoria and Albert Museum in the 1890s and it was displayed as a reconstructed
period room. The return of the panelling to its original location at Sizergh was advocated by among others
Mark Girouard, an authority on England's country houses. The panelling returned in 1999 under a long-term loan. In 2017 it was reported that transfer of ownership to the National Trust had been made formal. The
bargeboards on the gables probably date from the seventeenth century.
