The National Centre for Horticultural Science and Learning for the Royal Horticultural Society on Wisley's Hilltop will contain state-of-the-art-scientific laboratories, extensive public exhibition space, teaching studios and new facilities for their nationally important Herbarium, science and library collections. The Centre will be complemented by three new gardens, The Wellbeing Garden by Matt Keightley, The Wildlife Garden and The World Food Garden by Ann-Marie Powell. 

The project will deliver a major upgrade and step change to RHS Science that will support the delivery of the new Science Strategy, enabling high quality new scientific research and sharing of best practice through public engagement in Horticultural Sciences. The Centre will help to safeguard the internationally important scientific collections for present and future generations.

The new facility will provide the environmental conditions essential to keep these national reference collections secure, and ensure they remain available for the purposes of study.

The Centre design takes a Y-shaped form which will be divided into two functional wings, an Activity and Education wing, and a Science and Knowledge wing, each two storeys in height. At the centre a naturally lit, central public engagement space will link the functions of both wings forming the heart of the building.
