Pitshill is a Grade II* listed house built in the neoclassical style and is located within the Parish of Tillington a couple of miles west of Petworth.

The rectangular house of two stories with an attic and basement has a main east facing façade built in 1760 to a design by John Upton, the Petworth Estate surveyor.

It is built in limestone ashlar with rusticated ground floor and a balustraded parapet over the side portions.

[2] The remaining elevations are brick and render decorated to match the east front and were constructed in the 1790s to plans influenced but not completed by Sir John Soane.

Further substantial works were carried out to the house in the 1830s as well as the later Nineteenth Century additions of a veranda and conservatory, these being removed in the 1950s leaving a classical style rectangular building.
