The gardens cover approximately ten acres, including a striking woodland quarry garden.
The formal terraces near the house exhibit all the classic features associated with Arts and Crafts gardens.
There are far reaching views (borrowed landscape), yew hedges, multiple water features, herbaceous borders, sunken gardens, seating formal lawns and sculpture.
The woodland area is filled with rhododendrons, Japanese acers, and moss-covered rocks. Stone steps lead through dramatic landscapes of waterfalls and rock pools.
Likely designed in the 1920s, the quarry garden remains a mystery. It may have been influenced by the renowned landscape architect Thomas Mawson (See Tilley-Garth) or one of his protégés. It could also be the work of Agathoniki-Helen Demetriadi herself, reflecting the growing involvement of women in garden design during the early 20th century.
It seems likely that she was influenced by the Japan-British exhibition of 1910, at White City London, a celebration of all things Japanese including gardens. Nearby Tatton Park, and its infamous Japanese garden were the result of Alan de Tatton’s visit to the exhibition.

FUNGI SURVEY
Since 2020, Manley Knoll has been the site of a major fungi survey, led by mycologist Attila Fodi. This ongoing study has identified over 200 species, including one previously undocumented in England. The survey aims to aid conservation efforts and highlight fungi’s vital role in biodiversity.
This project has united professional mycologists and amateur enthusiasts, fostering a deeper appreciation for Manley Knoll’s natural environment. Groundsman Tom Saxon describes it as an exciting journey of discovery, revealing an unseen world beneath our feet.
