Kew Gardens’ tropical Palm House to shut for five years for net zero makeover

Huge glasshouse, home to world's oldest potted plant, to get 50m refit as part of emissions-cutting drive at gardens

It has been the tropical jewel in one of the UK's most famous gardens for more than 175 years, and now the Palm House in the Royal Botanic Gardens, Kew is to get a green makeover.

The attraction, which houses Kew's tropical rainforest, will close for five years to allow engineers and botanists to transform it into the first net zero glasshouse in the world.
