Dedicated to the original family Sheddy Man Larry Here is the signal box with glazing to 3 sides, made from old victorian sash window inserts bought for 99p, solid stable door which was modified to take a window. Solidly built using 3" x 2" and finished with freeby felt shingles. All in total cost was about £400 and the inspiration came from a railway signal box to give storage shed with a potting shed use as well.
