Eaves stacks are located on the outer sides of the towers, and each wing has two ridge stacks.

The rear wings incorporate single-fronted and then double-fronted cottages. Lower projections have been added to each end and at the rear of the property. The interiors have been modernised. The building forms part of a group of four similar structures.
