The south west range of Priory House is the oldest part, dated stylistically to around 1400. It is a two storey range with an upper floor solar, a single space open to the roof originally, with magnificent timbers giving a decorative appearance. The trusses have vertical wall posts from sole plates (horizontal timbers along the base of the walls) at the ground floor up to the wall plates (horizontal timbers along the top of the first floor walls), and support the principal rafters on the underside of which are fixed arched braces going up to a high collar which joins the principal rafters. The structurally significant timbers still give an impression of light and space.
