No problem in getting a 1m square, all you do is measure from the edge of the pipe facing inwards. I knocked one up on a job a couple of months ago in about three quarters of an hour. Another plus is that you can easily dismantle it for transport/storage. Once you've got your strings set up mark where they go with an indelible pen then when you reassemble it you don't have to re-measure the distances.
