In numbers: The Mansion at Wakehurst

Unearth some key facts and figures behind our Mansion’s restoration project.

In late 2022, our Grade I listed Elizabethan Mansion was veiled in scaffolding for the biggest renovation project we’ve undertaken at Wakehurst. 

The shrouding was transformed into ‘Planet Wakehurst’, an expansive photo montage featuring plants from across the landscape, created by artist Catherine Nelson.  

Here we delve into some key numbers along the Mansion's journey.

The number of different bat species discovered nesting in the Mansion’s roof – including common pipistrelle, soprano pipistrelle and brown long eared bats.

The number of years that the Millennium Seed Bank was housed in the Mansion’s chapel before the new building opened in 2000.

The original acreage of the estate purchased by William de Wakehurst in 1205 – long before the Mansion was even built. Today, that’s equivalent to over 74 football pitches.

535  

The current acreage of wild landscape radiating from the Elizabethan Mansion. Throughout each season, there is plenty to explore so start your adventure today!

1590  

The year in which the Mansion’s design was commissioned by the estate owner, Edward Culpeper.  

1903  

The year in which the Mansion was purchased by Gerald Loder, a passionate plantsman, who sponsored many seed-collecting trips to diversify the landscape. 

He also gave his name to the Loder Valley Nature Reserve, our 150-acre haven of wildlife.

1965  

The year in which the Mansion, owned by the National Trust, was leased to the Royal Botanic Gardens, Kew. We now work in partnership with the National Trust to care for our collections and heritage areas.  

2,300 

The number of acres owned by the Mansion’s residents, the Lydell family, in the late 1600s. They expanded on the original 1,100 acres, using the landscape as a site for ironworking and agriculture. 

20,000  

The number of trees lost in the Great Storm of 1987. Although a huge tragedy, the sudden change in landscape opened up new spaces for landscape design around the Mansion, such as the Asian Heath Garden.

15,000,000  

The estimated cost today, in pound sterling, of the Mansion’s twin building in Newport, Rhode Island.

American sportsman and politician James J. Van Alen was given permission to use plans of Wakehurst by Lady Downshire, the estate’s owner at the time.

Completed in 1887, the American estate is now a student building for Salve Regina University.
