I Need A Workshop ....

Totally agree with Kev. Biggest is Best!

The concrete base wants to be a couple of inches above the surrounding ground level and exactly the same size as the shed. Around the base, a depth of a few inches of gravel (the size that cats don't like to use), so that drips off the roof soak away.

When the roof is felted, completely cover the roof again with another layer of felt.

Hope this helps.

hi Admin

Not wishing to sound a bit of a kill-joy, and it may seem like a waste of model flying pennies now, but your workshop will be there for a LONG time. (Mine was erected just over ten years ago and I can't believe how quick the time has gone, as it is 20' x 10' there is no way it can be moved without being emptied and dismantled from the top down.) Before embarking on the project, it might be pertinent to ask yourself the question "What am I going to do when the wooden base rots?"

If your answer is, "It doesn't matter, I will be living elsewhere in ten years", then go ahead. It will be someone else's problem. 
 

Jef - Do you have your workshop on the concrete base or have you got a wooden base on yours ?

I use to have a tree in my garden which was a good size, the top of the tree got removed years ago now but left a small stump and the roots, that going to be the tricky bit to big out, thay way i was thinking also of a wooden base, we shall see

Kev - to be honest i thought i was going to be easy and straight forward lol but things are never are, i did look at Railway Sleepers as a base but then i thought they might start sinking, as for the tree roots do they keep growing when there is no tree above ?

Hi all.

Trees don't stop trying just because someone has done some excessive pruning LOL.

Best thing to do is have a little patience, buy some root killer (at your local garden centre) and give it a few weeks to work. In a short space of time (relative to how much spare time you have, as it will be working when you are not there) the roots simply rot away to nothing.

If patience is something you don't have time for, like most modern people, either build a bonfire on top of the stump and keep the wood burning until it's all ash, or hire a root muncher.

These are like a rotavator and require a lot of access space around the stump, trust me though, digging the stump out will be very hard work, and if there isn't a good deal of space around it, that will make life even harder. 

My son in law had a row of nine conifers, along the back of his garden, about 10m tall. We cut them down and dug them out. At every opportunity we were hacking pruning and sawing, and having only just completed that task, it is two years since we started. It would have been a far, far better idea to have cut them down and applied some root killer. Once we had dug out all the roots getting rid of them was a right royal pain in the backside!!!

Yes JG, I have a wooden floor inside the shed. Even in the worst weather, it is always bone dry, it is also sealed against ingress of vermin between the concrete base and the floor. 

Hope this helps.
