British - apparently some US company stole my name
Several of those windows, the lower big ones, seem to be soldiers or other military uniforms. I think the windows have an English vibe, but this is fairly new construction. I've been to London a couple of times, and this isn't there. Doesn't seem to be at Sandhurst. i think this is more likely in a Commonwealth country.
Coming late to this but whilst the windows are quite British, the overall vibe definitely isn't quite right for the UK. Thinking about it - it's partly the vegetation, partly the reflecting pool which is something we're really not that into (compared to eg DC), partly we wouldn't have a building in this kind of complex - we have plenty of churches already so our memorials tend to be standalone statues or walls. And that kind of Portland stone, Byzantine/Art Deco-influenced style isn't that common here, but was common for the grander cemeteries/memorials in Flanders like Tyne Cot and Vimy Ridge so I guess it's not surprising that the dominions followed suit - the stone obviously stays cleaner in Oz though!
