Folly in Garden of Number 239

The folly in the garden of Number 239 on Mottram Road is a derelict structure that was likely built in the mid-19th century and has undergone alterations. It features a red brick core faced on three sides with coursed sandstone rubble and has a pitched glazed roof that is now severely damaged, concealed by a parapet. The building has a square single-cell plan and is situated on a raised terrace overlooking a stream, with a cylindrical tower at the north-west corner.

Designed in the Gothick style, the folly stands one tall storey above a basement and is symmetrical, with a recessed center flanked by square corner turrets. The central area includes a large two-centred arched doorway with a triple-stepped surround and a board door fitted with strap hinges. Above the doorway are a pair of imitation loop-lights, corbelled "machicolation," and a high stepped parapet featuring a lead coat of arms and a dressed stone with the raised lettering "1767" at the apex.

Each side turret has a tall narrow two-light window with y-tracery and a hoodmould; the left turret is now glazed with bottles, while the right is boarded. There are also a pair of loop-lights and a corbelled embattled parapet. The west side has a wide round-headed opening to the basement, with brick voussoirs and a corbelled sillband leading to a large rectangular window with a hoodmould and damaged glazing. The west side also features loop-lights on two levels and continues the corbelled embattled parapet from the front. The cylindrical tower at the north-west corner is corbelled from the basement level and includes two cruciform tie-plates, loop-lights, and an embattled parapet similar to the others.

The east side wall is made of white-washed brick, where it was once covered by the gable end of the former glasshouse, and features a large square-headed doorway. A tall narrow embattled turret rises through the center of the embattled parapet. The rear wall is constructed of red brick. Inside, the walls are white-washed brick, and the pitched glazed roof is damaged. The folly is listed for its group value with Number 239, Mottram Road.
