Merton Hall Shellhouse 340 Metres West South West Of Merton Hall

Merton Hall Shellhouse, located 340 metres west-southwest of Merton Hall, is a garden house built around 1846 by architect Edward Blore. The structure is made of brick with some stone dressings and features a corrugated tile roof in a Tudor style. It is a single-storey building with clasping polygonal buttresses at each corner, topped with stone pepperpot finials. The gable ends have crowstep gables with pepperpot apex finials. The entrance is located in the gable-end and consists of a timber 4-centred arch with spandrels, leading to a part-glazed panelled door. Flanking the entrance are ovolo-moulded arched windows, with a larger similar window in the gable. There are five blind arches on one wall and two cusped Gothic windows with oculi in between on the other side, which are covered by wooden shutters. The building also features moulded brick dentil cornices and a rear gable-end with a canted oriel window made of timber. The parapet is crenellated, and there are pediments above the three shuttered openings.

Inside, the walls and roof are entirely covered with seashells arranged in various patterns, and there is a mosaic floor. An arched opening leads to the oriel window.
