The Palm House and historic glasshouses at Kew

The Palm House is one of the best-known historic glasshouses in Kew Gardens. It was built between 1844 and 1848 to designs by the architect Decimus Burton, with construction carried out by Richard Turner. The iron-and-glass structure protects tropical and subtropical plants, including more than a thousand species listed in Kew’s current description. An elevated walkway offers views of plants at different heights. The glasshouse is at once a botanical collection, an architectural landmark and part of a living research institution. Access arrangements may change in the future because of extensive restoration plans.

When the Palm House was built in the 1840s, the combination of iron and glass made possible a new scale of glasshouse construction. Plants from tropical regions could be cultivated in a building that let in light while allowing the required climatic conditions to be controlled. Kew describes the glasshouse as one of the oldest surviving Victorian structures of its kind. Its sweeping roofline and delicate metal framework make an impression from the outside; inside, palms and other plants reveal the building’s full height.

Decimus Burton designed the building, and Richard Turner brought the structure to life. Kew notes that shipbuilding techniques played a part in the design. This helps explain why the arched roof is often compared to an upside-down ship’s hull. The comparison is more than visual: it points to the transfer of engineering techniques between different types of construction. The Palm House shows how Victorian engineers used new materials and construction methods to create a controlled environment for plants on a grand scale.

The collection in the Palm House focuses on tropical and subtropical plants. Official information lists more than a thousand species from different tropical regions; many are threatened in their natural habitats. Visitors encounter towering palms, climbing plants, ferns and other plants whose forms are adapted to warm, humid conditions. Labels help identify individual species. The collection also illustrates the breadth of tropical plant diversity and how a glasshouse can bring different plant habitats together under one roof.

The Palm House is not simply a generic display of tropical plants. Kew’s gardeners and scientists care for the collection. Plants must be maintained, propagated and adapted to the conditions inside the building. Kew also describes the glasshouse as a living laboratory for research and conservation. This function brings visitors and science together, although visitors do not have access to all research activities. The display offers a glimpse of the plant world, while the botanical work extends far beyond it.

Inside, there are two ways to view the collection. From ground level, paths wind between plant trunks, shrubs and smaller specimens. An elevated walkway offers a different perspective on the tree canopies and climbing plants. This change in height is especially revealing, linking the glasshouse’s spacious interior with the structure of tropical vegetation. The walkway brings plants near the upper glass surfaces into view, while the paths below offer glimpses of the undergrowth.

A historic glasshouse faces challenging conditions: heat, humidity and changing weather take their toll on metal, glass and joints. Kew describes the Palm House as being in need of major restoration and is carrying out extensive conservation work. The aim is to secure the listed building for the long term and improve its energy efficiency and technical performance. The restoration affects not only the structure but also the plants, which are to be relocated temporarily and later returned to the glasshouse.

The work is an example of how to care for living heritage. The building must be preserved, while the plant collection needs suitable conditions during construction. Kew is working with specialists in conservation, engineering and horticulture to achieve this. The glasshouse’s historical construction can still be understood in its own right.

The Palm House is one of several historic glasshouses at Kew. It differs from the Temperate House, which is designed for plants from temperate climates, and from other specialist glasshouses. In the gardens, the Palm House and its surrounding grounds form a striking visitor destination. Its location near Victoria Gate makes it an early stop on many walks. Nearby are a parterre, a pond and other garden areas that change with the seasons. This makes it easy to combine the architecture and plants with a walk outdoors.

A dedicated look at the Palm House focuses on its construction, collection and restoration. Kew’s general overview, by contrast, explains the wider botanical and landscape setting. This distinction helps avoid repetition: Kew’s history encompasses research, collections and many buildings, while the Palm House brings together a more specific story of historic glasshouse architecture and tropical plants.

Who designed and built the Palm House?

Kew identifies Decimus Burton as the architect and Richard Turner as the ironworker responsible for the construction. The glasshouse was built between 1844 and 1848.

What plants grow there?

The Palm House displays tropical and subtropical plants. Kew lists more than a thousand species from the tropics; the exact collection may change as plants are cared for or relocated.
