[2] The present building was designed and built around 1720 by its owner, Sir William Wentworth, assisted by James Moyser, to replace the earlier hall.

In 1792 it passed into the Beaumont family, latterly Barons and Viscounts Allendale, and the library and dining room were remodelled by John Carr in 1793.

Before the sale, the panelling of the "Henry VIII parlour" (preserved from the earlier hall) was given to Leeds City Council and moved to Temple Newsam house.

The oldest part of the house, the south range dates from about 1720 and was designed by the owner, Sir William Wentworth and Colonel James Moyser.

[1] The house has a three-storey nine-bay by five-bay main range while the rest is two storeys high.

[1] The seven-bay north range has a symmetrical facade where the three centre bays have giant pilasters supporting a pediment.

Its seven bays are divided by square Tuscan piers which support the frieze, cornice and blocking course.

[1] The entrance hall to the south range has a groin vaulted passage with three arches and piers and its walls are decorated with grisaille paintings.

The link range has an entrance vestibule with four piers supporting a glazed dome on pendentives.

The library had an apse where there was an organ, a coved ceiling with rinceau decoration, and a marble fireplace.

[6] The redundant Grade II* listed St Bartholomew's Chapel, West Bretton built by William Wentworth in 1744[7] has been restored as gallery space.
