The panelling was already done when we bought it, James, plus a decked area that you can just see behind the 90. Now we have the awning down, I'll be dismantling the wood work tomorrow. Already done the decking and one side. Then it's get it back down on it's wheels and moved.
They're going to do drainage work and level out the pitch and the two next to ours.
I'm sure there's enough of the lads down there, with trailers, vans etc to move you with little expense. I moved here with a pickup and cattle trailer.
