Robert Matheson’s immense 1856–1858 Palm House combines a classically ordered sandstone base with a soaring two-stage iron-and-glass roof. Restored through the Edinburgh Biomes programme, it is scheduled to reopen with its older neighbour on 2 October 2026.

Architecture
The building is a long, arched rectangle joined to an earlier octagonal Palm House at the rear. Its massive Bishopbriggs-sandstone base is organised as a classical arcade: tall round-headed windows stand between pilasters beneath a continuous entablature. Above, curved iron rafters carry a convex glazed roof in two stages, lifting the crown far above the masonry walls. Historic Environment Scotland’s brief 1970 description calls the pilasters Roman Doric; the Garden’s history uses the contemporary wording “Tuscan-style façade”. Both point to the deliberately restrained classical treatment of the stonework rather than to two separate building phases.
The contrast is the key to the design. The base reads as weighty and permanent; the glass roof becomes progressively lighter as it rises. The linked octagon recalls the first Palm House of 1834, while Matheson’s larger house provided the extra height demanded by the Garden’s growing trees. RBGE describes it as the world’s tallest traditional Palm House.
Building for a living collection
The architecture was never simply a display shell. Its volume, glazing and heating created an artificial climate for plants gathered from warmer regions, making horticulture, engineering and scientific collecting inseparable. The great height allowed palms to mature without immediately meeting the roof; the repeated arched windows and curved glazing admitted light across a deep interior.
The relationship between the two nineteenth-century houses has changed repeatedly. A partition was inserted in 1859, removed in 1874 to form one tropical zone, and later reinstated. The latest restoration has removed it again, reconnecting the houses as a single visitor and growing environment.
History and development
The Royal Botanic Garden moved from Leith Walk to Inverleith in the 1820s. Its first Palm House, an irregular octagon, opened in 1834. By the mid-1850s specimens were already outgrowing it, and Parliament provided £6,000 for a much larger house. Robert Matheson’s new building was completed in 1858 beside the older structure.
Changes in plant display and environmental control continued. In 2005 the “Windows on the World” project opened up the Temperate Palm House so that architectural elements previously concealed from visitors could be seen. By 2017, long-term weathering and inefficient systems made comprehensive renewal necessary.
The 2022–2026 restoration
Major work began in 2022 as the first phase of the Edinburgh Biomes programme. Before construction, horticulturists removed about 800 plant specimens from the Palm Houses. Conservation repaired 600 square metres of surviving Georgian and Victorian ironwork, while more than 5,000 panes were formed from individual templates and designed to cope better with a changing climate.
Replanting began in 2026. RBGE expects around 600 specimens to return, including threatened plants and a young Sabal palm descended from one of the Garden’s oldest specimens. The work therefore conserves both a Category A building and the living collection for which it was created.
Why it matters
The Palm House is an unusually direct union of classical architecture and Victorian iron-and-glass engineering. Its value also lies in continuity: it remains part of a working botanic garden, shaped by changing scientific practice, plant growth and environmental technology. The older octagon, Matheson’s much larger addition and the restored shared interior allow visitors to read nearly two centuries of glasshouse development in one place.
What to notice
- The transition from the rusticated-looking weight of the sandstone base to the slender glazed roof.
- The rhythm of tall round-headed windows and pilasters along the principal elevation.
- The two-stage profile of the convex roof, which gives the building its exceptional height.
- The junction with the earlier octagonal Palm House at the rear.
- Inside, the restored iron structure and the way the planting uses the full vertical volume.
Visiting and access
Checked 25 September 2026: the Palm Houses are scheduled to reopen to the public on Friday 2 October 2026. Entry will be by timed ticket and RBGE recommends advance booking. The surrounding Garden is open daily from 10am and general Garden admission is free, but access to the restored glasshouse complex is a separate ticketed visit.
RBGE states that access after reopening is limited to the Palm Houses: the other glasshouses remain closed during continuing restoration. Conditions and booking arrangements can change, so visitors should check the Garden’s current visitor page before travelling. The West Gate on Arboretum Place is the closest named entrance in this record; the Garden also has an East Gate on Inverleith Row.
Timeline
- 1820–1824 The Botanic Garden relocates from Leith Walk to Inverleith.
- 1834 The first, octagonal Palm House is built.
- 1855–1858 Parliament funds a larger house; Robert Matheson’s sandstone, iron and glass building is completed.
- 1859 A partition is installed between the two houses.
- 1874 The partition is removed to create a single tropical zone; it is later reinstated.
- 2005 “Windows on the World” reveals more of the Temperate Palm House’s architecture.
- 2017 Plans develop for comprehensive renovation of the Palm Houses and later glasshouse range.
- 2022 Major restoration begins as part of Edinburgh Biomes.
- 2 October 2026 Public reopening of the restored Palm Houses is scheduled.
What we know — and what remains uncertain
The statutory designation is unusually concise. It securely identifies Robert Matheson, the 1856–1858 date, the arched plan, classical pilasters, two-stage convex roof and rear octagon, but it is not a full building history. RBGE’s current interpretation supplies the broader chronology and restoration account. Its visitor information concerns the linked Palm Houses as a combined experience, whereas LB27914 is specifically the large house; this record keeps that distinction visible. The reopening date and access arrangements are operational information and should be rechecked after 2 October 2026.
