Martin Booth's residence up on the Peak (his family was in Block A).
Today's google map shows the area is now known as 'The Mount Austin', and consists of several house, blocks of flats, and a clubhouse. If you want to relive Booth's time on the Peak, I see a 1200 sq. ft. flat in the development is available to rent for $55K a month.
It must be a new development, as my 1999 street map still shows the four blocks A-D of Mount Austin Mansions.
