Just before the local college was closed down to be moved to a brand new site, one of Alex's friends uncovered what looked like aged tracing paper. On closer inspection, this old piece of tracing paper revealed plans of Grovehill. The date can't be easily made out other than a word which looks like it could be 'January' and a year that's either 1960 or 1968. We think it reads '1968' as 1960 seems a bit early.
Alex was able to scan the huge document at very high resolution but only in monochrome (black and white) but is going to try to get it scanned professionally in colour which may help expose more detail.
