Hello exposed concrete. We were planning to go with the wood / aluminum option. Large-format sizes are planned (for example, floor-to-ceiling on the ground floor). The calculation here is 800€ per sqm of window. So mathematically, this already results in a "nice" six-figure amount for our project. But I think you can do quite a bit with the price per sqm. Thank you for the information.
Rick, thanks to you as well for your - as always - good opinion. We have a Josko showroom just around the corner and will visit it. Your option is of course absolutely brilliant. Definitely noted!
