In the world of interior design, trends come and go, but there are certain rules that remain constant. For classically trained interior designers, spacing and arrangement are just as important as picking the perfect art and furniture. If you’re looking for ways to refresh your apartment, then you might want to reconsider rearranging your existing pieces before you go out and buy new furniture. A couple of spacing adjustments can sometimes make a bigger difference than a brand new couch or a new piece of artwork. And when rearranging, feel free to experiment with different layouts. You’re just moving stuff around, so as long as you don’t puncture a hole in the wall, nothing is permanent.
