Brick walls for an observatory?

This would certainly keep the inside wall of bricks cooler but the warm outside wall would cause a rising plume of warm air all around the observatory until they reached ambient temps, correct ? -Tim
If money wasn't an object (brick seems to be pretty expensive these days), I would think that you could build an airspace between two walls of bricks, to provide an air-space and insulate the inside from outside wall. I've seen late 1900's brick homes built this way.
That would be my guess, based on experience.

One problem is that I don't know they export to Australia? And if we move it would most likely be overseas again. From the site it does look like they do kits though so I'll keep it in mind
Shipping to Australia would likely be high. However, a similar design would not be difficult to build by yourself.

I think from a seeing perspective wood is close to ideal though

Fake brick panels look like *BLEEP* when it comes outside corner joints etc
Yes I can imagine they have a tendency to peel open if you're not careful just how they're set in place. I think we'd be aiming for a painted look regardless so there's more options for fillers etc if you don't care what the colour of them is.
I do worry that if we grew plants up the side (as apparently we will I'm told) they'd creep in the joints and bad things would result

Well, that fine scope of yours DOES need a classy observatory!!
What about the idea of making fake face bricks out of wood timber pieces, cutting something like 2x8" stock into 16" long pieces, bevel the edges so as to look brick-like, and apply them over a plywood skin (could be screwed on from inside the skin) Decorative sections could be shaped into the wood or created with different thickness stock, and if you painted it with textured paint, would look very brick-like from a distance......or you could stucco it for a more real, and more fireproof, exterior. The whole could be made to be light enough that it could be un-bolted from its foundation piers and loaded aboard a tilt-bed truck.
An 8-sided structure built this way would be quite elegant!

Yes it's about time it had a proper home. We might use some sort of wood and a stucco effect - still debating. I'm actually doing experiments with the roof materials to see what's best in the sun. So far a double skin of aluminium is the winner.
There's also the question of what kind of roof. My wife's totally set on a roof that essentially disappears because she like just watching the sky - especially the satellites going over. But from the outside we want it to look like a domes structure. So, current plan is a system like a pedal bin, where the dome flips over and off

Of course you will probably have to mortgage your house to do it.
Kinda cool actually but I'm sure besides the cost, there are a host of other impracticalities but interesting none the least.
