Now that I have cleared 2 feet of cow poo out of my old barn I am ready to get it converted into my Stratos build workshop. Having seen Mel's garage/workshop I realise that there are many pitfalls to designing a new workshop from scratch, as well as loads of advantages! Basically I will have a 15m by 5m concrete floor with breeze block walls and a steel roof (wriggly tin). I am trying to buy a steel roller door that has been sitting on the floor at work minus its electric motor for £250.
What I am after is the words of wisdom from those who have built kits on what facilities to fit and what to avoid. I cannot build a pit as the ground is not suitable (nor are my pockets deep enough).
All suggestions welcome.
