Cement
Cement has a very long history with the human race. When we first started learning how to make and use cement it revolutionized the way we build everything. It seems that now we have come almost full circle and just use the cement in its raw state. No decoration or paint, just cement.
This very minimalistic approach just looks dead and offers nothing other than a support beam. There is an opportunity to do something with it, leaving it like this can just make everything feel cold and unfinished. Make sure that you do not leave giant pieces of exposed cement around your home, you can thank us later.
