Definitely think carefully about which side you’d like the narrower door to go on. I stupidly didn’t consider the thickness of the narrow door and ended up making the wrong choice. Assembly doesn’t allow for people to change their minds partway through unless you want to entirely undo the work you’ve done and start over. 

All that said, the piece is attractive and sturdy, and offers a lot of storage. I’m using it as a pantry and it works beautifully with my existing cabinets.
