Garden wall, gateway and summerhouse to north-east and south-east of the White House

The garden wall, gateway, and summerhouse located to the north-east and south-east of the White House were built in the mid to late 18th century, with the summerhouse dating to the late 18th or early 19th century.

The garden walls are made of red brick and feature a linear section that connects the rear wing of the White House to the garden pavilion of a detached outbuilding. A second linear section of garden wall to the south-west links the garden pavilion to a later summerhouse situated in the south-west corner of the garden.

The wall is constructed of hand-made brick in stretcher bond and stands about 10 feet (3 meters) high. It includes a plain stone gateway that provides access from the south yard to the garden. The summerhouse has a polygonal roof and features a doorway in the north wall with squared stone jambs and lintel. It also has triple ogee-arched windows with squared sandstone surrounds and impost blocks. The simple design of the ogee-arched windows indicates their later construction date.
