−	Decimus Burton’s monumental Temperate House precinct at the Unesco ~~world heritage site~~ of Royal Botanic Gardens Kew ~~is half-way through~~ a ~~£36~~ million restoration project.	+	Decimus Burton’s monumental Temperate House precinct at the Unesco World Heritage Site of Royal Botanic Gardens Kew was reopened in May 2018 after a 5-year, £41 million restoration project.

	The Temperate House range of buildings has a number of longstanding defects, all related to inherent failures in the original construction detailing. As an architect, Decimus Burton was a leader in the innovative use of metalwork for large spanning structures and in the early use of cement. Study of the extensive archive records, including original drawings held at the National Archives, has helped inform the subsequent restoration.

−	The North and South Blocks both, unusually, incorporate wrought-iron posts and angled braces in their masonry piers, possibly to speed up construction, enabling the main structure to rise before the masonry was completed. This feature is coupled with the use of dense cementitious renders throughout the whole building. Together these give rise to problems of entrapped moisture, iron corrosion and cracking of masonry. Without complete dismantling and rebuilding of the structure, the solution proposed is the introduction of a new cathodic protection system, designed by Corrosion Engineering Solutions. It is hoped that the range of techniques proposed will suppress the corrosion of the metal structure and metal components within the masonry by providing the electrochemical condition to control the corrosion process. This will result in less cyclical differential movement and resultant cracking of the cement render.	+	The North and South Blocks both, unusually, incorporate wrought-iron posts and angled braces in their masonry piers, possibly to speed up construction, enabling the main structure to rise before the masonry was completed.

	This restoration, project-managed by Turner + Townsend, will strip the building down to reveal its original metal and masonry core, carry out repairs, and repaint with the latest high-technology, long-lasting and protective paints. The existing irrigation and ventilation systems are no longer functional and sustainable; effective solutions are being implemented to provide the very best conditions for the new collection of plants.

	The existing sculpture within the Central Block, somewhat overshadowed by the planting, includes works by Cheere and Rysbrack. The careful restoration of these, and of the urns and decorative plasterwork on the building, is being undertaken by Taylor Pearce. In the case of the urns the aim is to restore structural integrity to the socles and replace missing finials. The sculpture will form an integral part of the new interpretation and visitor interaction proposals.

−	The present all-over, brilliant white, decorative scheme inside and out is significantly different from that of the original. Moreover, it covers architectural detail previously left unpainted, particularly the high-level sculptural terracotta figures on the east front. Research by Catherine Hassall revealed a total of up to 13 different paint layers in the older parts of the building. Early schemes within the 1860s buildings exhibited stone-coloured walls and a pale blue and off-white decorative scheme on the structure (not untypical of decoration with a late-Regency influence). This changed to dark green schemes on the metalwork with the addition of the later North and South Blocks (which thus never received the blue scheme).The final design will be developed in coordination with both London Borough of Richmond and Historic England, in order to provide the best possible setting for the foliage and sculptures.	+	The present all-over, brilliant white, decorative scheme inside and out is significantly different from that of the original.

	The project is not solely focused on the built fabric of the Temperate House. As part of the construction process and wider educational emphasis of the project, the main contractor, ISg, is offering six three-year heritage conservation apprenticeships and Kew is directly employing a further 10 focusing on horticulture.

−	Lying at the heart of London’s Kew Gardens, in spring 2016 the Temperate House is shrouded in a plastic, scaffold cloche, mimicking many of the plants within the botanical gardens, the metamorphic transformation of winter to spring. Yet the Temperate House has at least one more winter of transformation ahead, to complete the £36 million restoration project for the client Royal Botanic Gardens Kew, prior to the formal re-opening in May 2018. Substantial funding support from the Heritage Lottery Fund of £15 million, a DEFRA donation of £1 million, and a range of private trusts, donors and contributions from the visiting public are allowing for an expansion of Kew’s education programme, and public engagement and participation activities.	+	Lying at the heart of London’s Kew Gardens, in spring 2016 the Temperate House is shrouded in a plastic, scaffold cloche, mimicking many of the plants within the botanical gardens, the metamorphic transformation of winter to spring.

	The 30-month construction period is half-way through, with a handover back to Kew programmed for April 2017. The Temperate House will then remain closed for a further 12 months as it is re-landscaped, replanted and fitted with new visitor interpretation.
