Kew Gardens, the renowned botanical site in South West London, has taken a significant step in its ambitious renovation of the iconic Palm House and Waterlily House. To protect some of the world's rarest and most threatened plants, two state-of-the-art glasshouses have been constructed as temporary homes during the restoration process.
Innovative and Sustainable Design
The new eco-glasshouses feature advanced systems to regulate temperature, humidity, and light while prioritizing sustainability. Although they will not be open to the public, these structures ensure the safe relocation of plants currently housed in the Grade I-listed Palm House and Grade II-listed Waterlily House.
One of the glasshouses, built near the Palm House, is a temporary structure that will be dismantled after renovations are complete. The second, situated in a behind-the-scenes area, will serve as additional tropical nursery space once the refurbishment concludes.
A Milestone for Kew’s Sustainability Goals
This project aligns with Kew Gardens' 10-year corporate strategy, introduced in 2021, which aims to achieve climate positivity by 2030. Part of this strategy involves transforming the Palm House and Waterlily House into the world’s first net-zero glasshouses.
The renovations will replace outdated systems with net-zero carbon solutions for heating, cooling, and ventilation. Additionally, the project will address building accessibility, improve staff facilities, and enhance health and safety measures.
Preserving a Living Legacy
Built in 1844, the Palm House hosts a diverse collection of tropical plants, including species that are endangered or extinct in the wild. The Waterlily House, completed in 1852, was originally designed to display the giant Amazon waterlily and now houses aquatic plants and tropical fruit.
In preparation for the plant relocations, Kew’s scientists have been busy with pruning, repotting, and propagation. While smaller plants will be moved this year, the larger relocation effort will begin in spring 2024.
Leading the Way in Conservation and Innovation
Richard Barley, Director of Gardens at RBG Kew, expressed enthusiasm for this milestone, stating:"We are proud and excited to announce the completion of these new facilities, which not only support the conservation of some of the world's rarest and most endangered plants but also reinforce Kew's legacy as a leader in horticultural innovation."
The project underscores Kew’s commitment to setting a global standard for sustainability and botanical garden management while continuing its mission to protect and conserve plant biodiversity.
