Industrial chic is all the rage right now and the Hillside House by SB Architects is the most beautiful specimen of this style I have come across. While the finishing materials of iron and concrete would lead you to think of a frigid and cold space, the loads of wood paneling and perfectly executed lighting make the home warm and welcoming.
I simply adore the wallpapered ceiling. It's a great way to add a little whimsy to a kid's room while still keeping with the minimal clean white walls.
Another example of concrete in a bathroom. Stunningly beautiful.
