1940s warehouse

Haha - yes! Thank you, Ulrich.

I wish I could get inside this building! The roof is caved in, though. Thank you, Leon!

It looks to me like an industrial version of the Art Deco - Moderne combination. The zig-zag detail is something I've seen around, but don't know that is has a name of its own: il9.picdn.net/shutterstock/videos/18858536/thumb/1.jpg

Art Deco here is, I think, the same as yours, but the true, gorgeous form is found in big cities like Chicago. Elsewhere, it is usually simplified or combines with other styles. As I sit here looking at 40s & 50s architecture on Google Image, the above building reminds me of small town Soviet buildings and monuments. What that derives from, I'm not sure, but it's cheap materials and mix-and-match design like the above. Maybe Brutalist influence...

Interesting link Diane..........I can see the similarities.

Wherever the design came from, it certainly looks as if someone made an effort to impress..!!
