[3] The area presently occupied by the Belmont Hall estate was granted to Norton Priory by Geoffrey Dutton in the 12th century and became a monastic grange, of which only the fishpond and moat have survived.

Some of the architectural features of the house are inconsistent with Gibbs' work elsewhere, and it is considered by de Figueiredo and Treuherz, and by Hartwell et al. that changes to the design, including the two-storey bow windows, were made by the executant architect.

[8] The estate remains in the ownership of the Leigh family; the house is let to Cransley School, and part of the surrounding land is used as a registered Camping and Caravanning Club site.

[1] It is designed along Palladian lines, with a central block of living rooms, separate side pavilions for offices, stables to the west and kitchens on the east.

Around the top of the house is a moulded cornice, a plain parapet, and a central three-bay pediment containing the coat of arms of the Smith Barry family and their motto.

Each pavilion is joined to the house by a wing wall containing a central round-arched pedimented doorway and two 12-pane sash window, and is topped by a vase balustrade.

[11] In the staircase hall is a panel between the windows containing a bust of Diana, with decorative plasterwork including festoons and hunting trophies.
