The Estate was originally established as a mental health asylum in 1839 by Elizabeth Crichton, who was an early pioneer and advocate of the importance of connections with landscape and nature and its links to health and wellbeing. This formed the foundation of the proposal, which seeks to place nature and wellbeing at the heart of the building. The design focuses on a series of new gardens of different typologies, reflecting the spatial, sensory and therapeutic qualities of the historic gardens.
