From storage unit strategies to time-honored ideas like making sure every stick of furniture comes with bonus storage capabilities, were all trying to cram two houses worth of stuff into one house.If your house appears to be at full capacity and you just dont have any more room for shelves, cabinets, or anything else, you have one move left: Start literally carving storage out of the bones of your house. There are hidden voids everywhere, and with a little elbow grease and surprisingly little skill you can fill those hollows with your stuff. Here are a few easy ways to carve storage out of your home.Interior wallsNo matter what kind of house you live in, or what size it is, you have walls. And the interior, non-load-bearing walls in your house are probably framed with 2x4 studs and clad in drywall. If you remove the drywall, it will look something like this: Credit: sockagphoto/Shutterstock Those hollows can be pretty easily transformed into shallow shelf space. Framing 2x4s are actually about 3.5 inches deep (for reasons), which is actually just deep enough for paperback books or any small items (e.g., spice bottles, bathroom supplies). Here are the basics for carving storage out of your walls:Use a stud finder that also detects wiring and plumbing, like this one. You want a section of wall free from clutter that also doesnt threaten to electrocute you or flood your house if you slip with the drill. Use the stud finder to map out where your studs arethey should be either 16 or 24 inches apart, but you can run into weird exceptions, especially in older homes or homes where a DIY maniac did a lot of their own work.Decide how tall you want your storage area to be, and use a utility knife or multitool to cut out the drywall.Paint the exposed back of the other side of the wall, or cover it with wallpaper or whatever else you want.Take a 1x4 and cut two one-inch pieces for each shelf youre going to add. Screw these into the studs on either side of your opening at the heights you want your shelves to be. Use a level, for goodness sake, to make sure your shelves will be level. Alternatively, you could drill pin holes for shelf supports so you have adjustable shelving; pin holes are typically 1/4 inch in size, but you should pick your shelving and check the diameter of the supports before you commit.Cut 1x4s or 2x4s to size to act as your shelves and set in place.Trim the opening with more 1x4 (or whatever you want, if youve got some woodworking skills), fill holes, caulk, and paint.Voila! Viable storage set into the wall. You can add one or more of these storage options anywhere in the house, and if you dont need them any more you can just remove the trim, drywall over the opening, and forget it was ever there.StaircasesThe stairs in your house represent a lot of wasted space. If theyre open, meaning you can already access the space under them, you have a few simple options for turning that space into usable storage, including sloped shelf brackets (and/or sloped clothing rod holders) attached to the underside of the stairs, some appropriately sized stock cabinets, or simply stacking up some storage cubes in a neat geometric pattern.If the stairs are closed (meaning the empty space below is covered by drywall), you can get more ambitious and create built-in storage under there. This could be as simple as replicating the in-wall storage described abovecutting out some drywall between studs to gain access to the void under the stairs, then adding a small door for accessor getting fancy with a set of pull-out shelves (this might be a project worth hiring a carpenter for). As long as you dont mess with the support structure of the stairs theres no reason you can use that void underneath.Toe-kicksThe toe-kick is that part at the bottom of your kitchen and bathroom cabinets that are set back so you can stand super close to the counters. Theres usually nothing but empty space behind them so they are an ideal spot to carve out some extra storage for your house.You can buy kitchen cabinets with toe-kick drawers already included, but if don't have those, you can add toe-kick storage to existing cabinetrybut it requires custom-built drawers. You can find folks to make them for you on Etsy, or hire a local carpenter to build them for you. Then its just a matter of removing the existing toe-kick cover, installing the drawer slides, and then inserting the drawer itself.Keep in mind that these drawers will be very shallowyoure not getting pots and pans in there. But they will enable you to get a lot of smaller stuff off your counters and out of your other drawers and cabinets, opening up plenty of extra space.FloorsLike walls, your floor is a system of joists spaced 16 or 24 inches apart, and you can cut a section out of your floor between joists, build in some storage, then re-attach the floor section with a hinge and a handle to create storage under the floor. This is a surprisingly simple project, though youll have to get comfortable with cutting up your floor:Figure out where your joists are, and measure out how large you want your storage to be. Make sure pipes and wiring arent going to get in the way.Mark a section of the floor thats about a half-inch wider. This will create a lip of joist that the section will rest on when closed.Cut out your floor and subfloor, being careful not to cut into the joists themselves.Build a simple plywood box and insert it into the space youve created, attached to the joists.Turn your section of floor into a trap door.Fill up your new storage box and drop the door into place. If you take care with your build, it will be nearly invisible.
