The Kew Orangery was built in 1761 by architect Sir William Chambers. Perhaps the largest classical building in Kew Gardens it is Grade I listed. It is also an example of how a failure can live on as long as it has qualities.
 
Originally, it was intended to house citrus plants like lemons and oranges, with features such as underfloor heating to support their growth. However, the building proved too dark for the plants to thrive, so they were relocated by 1841. Over the years, the Orangery has served various purposes, including as a museum for British timber from the 1860s until 1959, and later as a tea room and now a restaurant and events venue.
