So not to tax your brains too much there is only one simple stage to this puzzle. In front of you there should be a big Red Box:
Above the silver door there are three words, the number of letters in last word = A
Coordinates for the find are:
N 50° 49.A+1 A+2 A-2
W 000° 21.A A+1 A+5
Checksum of all individual numbers in coordinates = 52
It's a nice little mooch to the find.....
