Default Critter Roundhouse?

Hi all.
I wondered what a Critter roundhouse might look like - using the 5" turntable. So heres a very quick mock-up, no features - just lasercut mdf walls and roof taped togther.
Imagine it in framed timber with batten and board walls, roof trusses and corugated iron roof with smoke jacks, doors and windows.
I started with 2 stall, and grew from there. Each stall is 6.5" long. door opennings are 2 1/4" wide by 3 1/4" tall (big enough for critters?). Dimensionally it is based around a 10" decagon - so a full round house would have 9 stalls and an entry road, and be 23" in diameter. This one is a 4 stall - more manageable in size.
what do you think?

It's interesting.
If I can say: most roundhouses had the side walls on a raius from the center of the turntable. I think it would allow easier expansion and they liked more space at the end where they had to work on the loco's more complicated bits.
From a manufacturing viewpoint, all the outer wall segments and the bits of roof can be the same.

Good point Dave - the ends do look a bit odd being straight. will redo that part of the mock-up.
it would make the roofs a bit easier - particularly the rafters, and for sure the door openings and rear stall section would all be the same too.
The end walls will be similar but different because the inner "walls" are open - mostly just supports for the roof.
Thanks for the input.

I'm sorry that I'll have no use for one; the only On30 I have is a Galloping Goose.

I think this one's just for me Dave Its a bit of a wacky idea!
I want to try out some resin/plaster casting walling techniques -and figure this might be a vehicle to do that.
As well as your suggestion with the ends, also been looking again at the roof - I'll make another mock-up with the roof centreline going around the radius - that will be more prototypical too.
