The Temperate House is the world’s largest surviving Victorian glasshouse!  This substantial glasshouse is sited at the Royal Botanical Gardens Kew, which itself is a National Treasure and an UNESCO World Heritage Site.  The Temperate House is a Grade I Listed Building.  When this glasshouse’s refurbishment programme commenced work in 2013, the Temperate House was in a dilapidated condition, at this time the Temperate House was on English Heritage’s Buildings at Risk Register.
