Kew Gardens' Palm House: A Greener Future

The World Monuments Fund (WMF) is expanding its mission to include the preservation of historic green spaces, parks, and gardens. A key project is the significant restoration of the Palm House at Kew Gardens, London. This grand glasshouse, a marvel of 19th-century engineering, is undergoing a £66 million transformation to become a net-zero building. This restoration is scheduled to be completed, with the Palm House reopening in 2027, following the Waterlily House.

The WMF's initiative, "cultivating resilience," supports global horticultural programmes. These include efforts in Beijing's Forbidden City, a sacred forest in Nigeria, and historic agricultural fields in Peru. In London, the WMF has also funded a pilot scheme for the Tower of London moat and supported the restoration of St. George's Church in Bloomsbury.

The Kew Gardens Palm House restoration will involve replacing 16,000 panes of glass with new silicon gaskets and implementing a net-zero heating system using air and heat pumps. Rainwater will be used for plant irrigation, and revived roof vents will improve air circulation, significantly reducing operational costs and environmental impact. This project aims to enhance the historic glasshouse while countering criticisms and ensuring its botanical and architectural significance endures.
