Thanks all for the kind words gents. I feel extreemely fortunate to be able to own such a great "boy cave". I owe a lot of people a great deal of gratidude.
Yes. It even comes with a kitchen sink
. I still need to do the plumbing. I'm looking at a 2.5kl water tank which I will place under the obs and I'll run a small water pump.
Mike, I've done some preliminary testing on the pier dampening and it looks to be fine. The bottom half of the pier is 300mm diameter concrete which has a ~1.5 tonne base sunk down to bed rock. The top portion of the pier is metal. It's based on 175mm square tubing with 2 stabilisation plates welded onto each of the 4 sides (ie, 8 in total). The metal pier weighs about 150kg (was fun lifting it into position).
Paul, I will certainly take your advise re the curtains. Actually, I have already bought the curtain material but I will also get some heave backing material to make sure minimal light escapes outside the warm room.
