Bump-out additions can add some space to a closet without requiring any significant structural work. This entails pushing back the existing rear or side of the closet, simply moving the wall into either an adjacent room or unused space. For ground-floor closets, this could even be extended to the exterior of the home, but that has its own complications. Bump-outs are a good discussion to have with your contractor if you’re just looking to increase the space a little—not renovate the entire closet space.

You can budget a little less money for how to build a closet with wire shelves than with wood shelves. Some people don’t like the aesthetics that wire shelves provide, though, meaning they’ll gladly spend a little more to add wood shelves to the build. If you decide to buy pre-made wire shelves instead of building custom-sized wood shelves, you’ll be restricted in the closet shelving dimensions you can use.

There are a few reasons custom closets are expensive: materials used, the luxury factor, and time to build. The people who can afford custom closets are those who can afford increased rates, and construction workers and contractors know this and charge accordingly. The time to build custom closets is substantial, especially if expensive material is being used or intricate details (like carved wood) are added to the project.
