The Grade II listed stable block was converted to residential use and new houses were built in the grounds.
In 2008 the current owners launched a garden restoration not-for-profit membership organisation called 'The Emes Society' (after William Emes – see above) with the intention of looking after the 10-acre (40,000 m2) garden and developing it for the 21st Century, with open days for the public including, e.g. a Bluebell Walk.
The formal part of the garden includes a magnificent Cedar of Lebanon planted by William Barron.
