The former kitchens at Kew Palace were built in 1730 in the Palladian style, and formed part of a larger royal complex - much of which has since disappeared. The Grade II listed building had lain undisturbed and unappreciated for over 200 years, today providing a fascinating snapshot of royal domestic quarters with many historic features and artefacts remaining intact. We were asked by Historic Royal Palaces (HRP) to undertake conservation work at Kew Kitchens, following the transfer of the building from the Royal Botanical Gardens, Kew. This work was informed by a detailed curatorial survey by HRP, and was the subject of two detailed listed building consent applications in 2010. Our work appeared as a “light touch”, concentrated on preserving surviving historical features, removing later inappropriate accretions and reinstating any features that had been lost through insensitive maintenance and refurbishment. As well as major structural repairs and work to address damaged masonry, carpentry and joinery, we worked closely alongside HRP to rediscover and reinstate the original first floor layout and recreate historic decorating schemes. Behind the scenes we refurbished office accommodation and upgraded the building services. Externally, we conserved a number of original historic features including paving and landscaping, and installed a platform lift to provide access to semi-basement kitchen areas. Kew Royal Kitchens, now reopened to the public is now an extremely popular attraction, giving visitors a unique insight into an otherwise unseen side of royal history. In light of the discoveries made and recent conservation works, the List Description has now been revised to Grade 1.
