I dug a base filled it with rubble and topped it with gravel; there is a pipe from that to pond so it should be all well drained .
I would use sapele if i was doing it again
there are no fancy joints at all because i was lazy and it doesn't really need them
although I would have made a better job of it had I had the time.
The side windows were a pain to do because there were so many and the roof was a pain because the timber was all bent.
sent it back but what they brought the next time was not much better.
I should have planed them all straight but some would have ended up like matchsticks :shock:
this is why i would never use pine again! don't know why i thought it would be any different but have been using oak mainly for years and simply forgot how rubbish pine is as supplied from normal timber yards anyway!
