Summer house overlooking the site of a former tennis court in Rivington Gardens at SD 6394 1399

A summer house with associated staircases built from 1906 to a design by Thomas Mawson for Lord Leverhulme. It is built in gritstone and is rectangular in plan.

The single-storey flat-roofed summer house overlooks the site of a former tennis court to the south and is accessed up a couple of steps leading to a broad centrally-placed entrance that is divided into three by two pairs of columns of thin, stacked gritstone. Similar columns are located at either end of the broad entrance. Slightly protruding bays to either side of the entrance each have a centrally-placed rectangular window opening with rock-faced gritstone surrounds. Staircases with associated flanking walls lead upwards at either side of the summer house and give access to a viewing deck surrounded by a parapet on the flat roof. The parapet is solid at each end of the summer house but is balustraded above the summer house's broad central entrance. Access to the interior of the summer house and its viewing deck is blocked by iron railings.
