Description

The Summer House in Radnor Gardens is a mid-18th century structure built in a 'Gothick' style. It is constructed of stone and features a tiled roof. The building has a polygonal shape with trefoiled ogee openings and wide ogee windows set behind. The glazing bars are arranged in a hexagonal pattern. The structure has been cemented and altered over time. This summer house is a remnant of Lord Radnor's architectural efforts in that style and is the only remaining part of Radnor House.
