Major projects at Wisley

Building a greener future 

RHS Garden Wisley, our flagship garden, is undergoing an exciting period of transformation. This amazing development, part of a £160 million investment programme by the RHS, celebrates both the garden’s heritage and our ambition to invest in the future of gardening.

The Welcome building and surrounding landscape has transformed the entrance to Wisley, putting design, plants and horticulture at the forefront for visitors to enjoy. Further future development will open up parts of the Laboratory building and create the UK’s first horticultural scientific centre of excellence in RHS Hilltop – The Home of Gardening Science. This ground-breaking centre for science and learning will inspire the next generation of horticulturists and show our previously unseen scientific work to visitors. 

During this exciting time, Wisley remains open for all to enjoy.

Preserving and growing our collections

RHS Hilltop will have the dedicated facilities we need to preserve, use and grow our unique collections and share them more widely.
