I’ve built myself a small workshop at the bottom of my garden where I have a gas forge and anvil, I only started 6 months ago so I’m doing small stuff. I’ve just received a letter from the local council saying someone has complained about this, stating this is a commercial building and commercial activities are being done. I’m just after a little advise regarding having a gas bottle and forge in a shed. Is this allowed ? It’s just a hobby and I’m no way selling anything I make. thanks stuart.
