We have several partners we work with. For this job I was contacted by my designer and asked to come help solve some storage issues. The bathroom was demoed when I arrived. a small closet was removed and the client needed storage.
For one of the drawers we added a drawer in a drawer. You open the main drawer fully, then you can push the secondary drawer into the cabinet to access the bottom of the main drawer. Good use of space and great for small storage items.
