That's alright, it might not be perfect but it should be good enough for experimental purposes. The glass wall gives you a higher loss factor at long wavelengths but you ought to be able to at least give it a try and see what happens.

We got the room ratios about right and the straight parallel walls and floor all have glass opposite.
In addition the conservatory roof is multiple pitched.
Soaks up the power but it doesn't have strong resonance in bass.
