Arranged along the original garden wall of Garboldisham Manor’s kitchen garden, near Diss, this remarkable four-bedroom house, known as The Walled Garden, is an example of great individual invention created by Michael Neylan and William Ungless in 1978. With an extraordinary one-acre private garden contained within the high walls to the rear, and a large drive to the front, the house has a magical sense of seclusion.
