I'm pretty sure our apartment doesn't even have a pantry, unless the thing we consider a broom closet was supposed to be a pantry (in which case it is very very poorly laid out). If we owned the place this is a perfect way to take a mostly useless broom closet and turn it into a fabulous pantry.
Most places will make custom drawers for you in the dimensions you need, or you could get crafty and make your own drawers. Slides are available in a variety of dimensions as well.
For this project you will have to take accurate measurements of the size of your pantry and how many drawers you will need. Use the tutorial at Remodelando la Casa for help getting your measurements just right.
After your measurements are perfect, collect your supplies and get to work. You'll have awesome shelves for your pantry in no time!
