Tom Stuart-Smith
Tom Stuart-Smith is a landscape architect and garden designer whose work combines naturalism with modernity and built forms with romantic planting based on close observation of nature. He read Zoology at the University of Cambridge before completing a postgraduate degree in Landscape Design at Manchester University. Tom has since designed gardens, parks and landscapes throughout the world.
Projects in the public domain include several at Chatsworth, a new public garden at the Hepworth Wakefield, and the masterplan for RHS Garden Bridgewater, which is one of the largest recent garden projects in Europe. At Bridgewater he was also responsible for much of the detailed design of the central area of the garden. In London he has designed Jellicoe Gardens in Kings Cross, a new Islamic garden commissioned by the Aga Khan Development Network and Argent, opened in 2021, and the dramatic recasting of a garden by St Paul’s Cathedral in the City of London with a large water basin at its centre, reflecting Sir Christopher Wren’s famous dome, opened in 2022.
Recently completed projects in the UK include a new garden at Knepp Castle that seeks to maximise biodiversity, and a new landscape to Aldourie Castle on Loch Ness in Scotland.
Current projects include gardens in Gujarat, New York State, Denmark, Spain, Germany and France. In the UK he is making a garden for Tate Britain, supported by the Clore Duffield Foundation and in collaboration with the Royal Horticultural Society which will open in September 2026 and a new garden for the National Centre for Music in the centre of Edinburgh.
