[Suggestion] Aluminium buildings are worse than stone

I'm guessing this just hasn't been balanced yet but alminium is far far worse than stone when it comes to housing. Rain hurts it, the HP is low, Wind hurts it too I think. It feels like wood, just much harder to manufacture. I dig that stone is mostly weather proof, but animals can still break in, that feels good. Maybe make each tier just a stronger material, 2.5k aluminium maybe 4-5k concrete etc. (I haven't done anything with concrete yet, it might already have great HP per piece)
