Outdoor benches - aluminum or as a roll layer of facing stones

I'm currently at work and don't have any pictures of the views here.

Yes, then post them later. A stylistic idea of the whole can indeed influence the opinion. Should the coloring also be as irregular / lively as in the example picture?

Yes, it should be like that too

I have the prejudice against aluminum that it is loud when it rains. Therefore, I prefer clinker.

That is not true. Aluminum only becomes loud if it is not properly placed on the window recess. If there is a small hollow space anywhere, it will be loud. We have aluminum windowsills and even when I stand next to them in the rain, I hear nothing but a quiet dull pattering.

I would also tend to go for the roller shutter. It looks more harmonious and I have also had bad experiences with aluminum when it comes to rain rattling. But my absolute favorite is granite.

So? Do you keep the window open when it rains? With triple glazing, you don't hear anything inside. IMHO
