Campaigning businessman Norman Thody, who has a disabled son, fought red tape and conservative thinking in the late 1970s and early 1980s to get the Oakenfield estate built.
Mr Thody, now retired in Cyprus, saw the charity he established, the Disabled Housing Trust, blossom and then celebrate with thousands of people when Princess Diana opened the Ernest Kleinwort Court complex next to the Oakenfield bungalows in 1985.
The charity grew to have its own UK offices at The Market Place in Burgess Hill and run other centres such as Hollyrood near Lindfield to improve the lives of disabled people across the UK under its modern-day name of the Disabilities Trust.
The charity has announced that it is teaming up with Global Adventure Challenges to offer what it calls a 'wide range of awesome experiences' including trekking along the Grand Canyon, London to Paris cycling, climbing Mt Kilimanjaro and climbing to Mt Everest's Base Camp.
