The Temperate House, opened in May 1863, is a Grade I-listed showhouse for the largest plants in Kew Royal Botanic Gardens. Rectangular, with pitched roofs, its pillars support wrought-iron ribs. Decimus Burton and Irish engineer, Richard Turner, the designers, gave the House a mix of decorative motifs, finials, pediments, acanthus leaf capitals, Coade stone urns and statues. According to Greg Redwood, Kew's head of glasshouses, "The effect is similar to the contemporary iron pier pavilions of Eugenius Birch."
