Boultibrooke House

Boultibrooke House is a Grade II listed building featuring a symmetrical U-plan design. The main block is two stories high with three windows and has an early 19th-century stucco front. It has a hipped slate roof with end stacks, wide eaves, and blind arches on the outer ground floor bays. The windows are sash style with glazing bars set in recessed timber frames, and there is a later glazed porch at the center of the front. The set-back stucco wings also have hipped slate roofs and feature a five-bay arched ground floor treatment, with a glazed verandah on the right. The right wing, which was extended in 1872, has a five-bay side elevation that is partly one story high, with Gothic glazing bars on the sash windows and a solid porch.

At the rear, there is a library extension added between 1812 and 1815 by Robert Smirke for Sir Harford Jones Brydges. This extension is an elongated octagon made of red brick, featuring top-lighting only. The interior, accessed through a domed anteroom, includes a coffered central dome and additional domes adorned with fleur-de-lys ornamentation, along with a plaster cornice featuring egg and dart motifs and a foliage frieze.
