Tittenhurst Park was located on a 72-acre estate on London Road in Sunningdale, Ascot. Lennon and Ono had bought it on 4 May 1969 for £145,000 from Peter Cadbury, an entrepreneur and the son of Sir Egbert Cadbury of the chocolate company Cadbury Brothers.
Lennon and Ono spent twice the purchase price on renovations, including the creation of a lake, without planning permission, which they could see from their bedroom window.
A recording studio, known as Ascot Sound Studios or ASS, was installed at Tittenhurst in 1970. Lennon’s Imagine album and Ono’s Fly were both recorded there. The sessions were filmed, and footage was later released in the documentary Gimme Some Truth: The Making Of John Lennon’s Imagine.
