It take it from the internal pics that it's two story? but it doesn't look that tall/big from the outside? Tardis?
Thank you sir! It's a little over 5 metres tall and 5 metres wide. That gives me enough room for a 2.4 ceiling downstairs with plenty of room for a solid observation deck above.
A few years back I built this observatory as cheap as. Based around 2.4 x 1.2 x 12mm ply. IOW it's an 8ft square. Didn't like roll-offs and couldn't afford a dome so I designed my own. A parting gable roof that rotates 360. Some drawbacks: I used polycarb roofing which is good for flexible overlapping (never leaks) but admits too much heat, and I should have made the roof structure out of sq. steel tube. Otherwise it works great. Only takes seconds to open and close.
My 'chook shed' with the roll off roof. Been up for over 10 years now and surprisingly no problems. The pine fence palings are rubbish and warp terribly so there's a few gaps for the wind to get in. Rabbits have dug a little home underneath, there's been the odd rat and a couple of bats too so it sure aint vermin proof. I put some small alloy channel running the length of each side and each half of the roof sits on four plastic wheels with steel bearing inserts and it only requires a couple of fingers to open and close. Built on complete ignorance and very little carpentry skills but it works nicely for me. Pier is just four pine boards joined together, concreted in and filled with sand - pretty solid although there's some vibration if you kick it
I finally got the door installed and can lock it up. Exterior is complete although I may add some solid side curtain boards at some point. The black plastic curtains have done a reasonable job so far but I'd like something a bit more professional looking. Working on the interior fitout now.
if I had that double storey one I would never leave it hahaha
