Description
Porcupine House is a house located on Hildenborough Road in Leigh, built in the late 19th century, probably by the architect Sir Ernest George. The house features half-timbered construction with a red brick plinth and stacks, raised, chamfered surface timbers, and roughcast panels. It has a clay tiled roof and tile-hung side elevations, with iron casement windows.
The building is two storeys high with an attic. Its steeply-pitched principal roof runs east to west, and the main elevation faces south. This elevation includes three gabled bays with overhanging eaves and pendants. The central bay protrudes, and to the right, there is a gabled porch with a tiled roof, supported by carved Jacobean-style posts. The door features carved linenfold panels.
Porcupine House is located north of the neo-Tudor lodge and gateway to Hall Place, which is no longer standing. The lodge and gateway, which are listed Grade II, were designed by the architect George Devey and date from the mid-19th century.
Porcupine House is designated at Grade II due to its architectural interest as a fine example of late 19th-century domestic architecture by a prominent architect, and it has group value with the lodge and gateway to Hall Place, creating an attractive ensemble of 19th-century architecture.
