Really Cool Stairs #11 - Concrete Stairs
For the record, we do not build concrete stairs! In my opinion however, if you want to accomplish an ultra contemporary look, concrete is a must. They may look cold and dull however their sharp lines and grey-scale appearance give them a very desirable look to any edgy architect. Take a gander through a few pictures I found, I honestly think concrete may be the way I go when I build my next house!
