The Temperate House, re-opened in May 2018 after being closed for restoration, is a greenhouse that has twice the floor area of the Palm House and is the world's largest surviving Victorian glass structure.
It contains plants and trees from all the temperate regions of the world, some of which are extremely rare.
It was commissioned in 1859 and designed by architect Decimus Burton and ironfounder Richard Turner.
Covering 4880 square metres, it rises to a height of 19 metres.
Intended to accommodate Kew's expanding collection of hardy and temperate plants, it took 40 years to construct, during which time costs soared.
The building was closed for restoration 1980–82.
The building was restored during 2014–15 by Donald Insall Associates, based on their conservation management plan.

There is a viewing gallery in the central section from which visitors can look down on that part of the collection.
