If you plan to add a room or bathroom to your basement, adding more walls will give the area more of a lofty feel.

Whether you want to create an extra room or add a bathroom, you can go about constructing walls in many different ways, but this article will show you one method of doing so.

If you want to add medicine cabinets to the bathroom, construct a 16 inch on-center wall frame, so fixtures like bathroom cabinets or insulation can fit snuggly between the frames. You can also go for 24 inch spacing.

Always be aware of the risks in trying to do these types of projects by yourself.

Building the Base

When it comes to the base, you can use double 2 x 4 boards (sill plates) or a single board as the base. Sill boards will connect the wood walls to the concrete. Find a good place on the ceiling for nailing in the top plate before establishing the bottom plate. If you're going for a single base board, drill pilot holes for the sill plate (bottom), but there are certain building codes regarding the spacing of these holes, so check with your local ordinance to make sure.

You can use a split-drive anchor nail will be the best method of establishing a solid base for the bottom sill plate, but you can also use mason screws. You can find a picture of one here.

The nails have a hardened edge so it can drive further into the concrete flooring. Since the flat end of the tip tends to chip away when hammering, goggles are advisable. Three inch screws will be necessary for 2 x 4 wood.

Things you'll need are a hammer drill, regular drill and a hammer. Have your moisture barrier ready to protect against moisture from entering the walls. For the floor, drill in your holes through the wood and concrete with the hammer drill first before hammering it in manually. You can drill in the hole a half inch deeper than the actual nail to make it easier when hammering. As you drill up from the concrete, you're going to get a fair amount of concrete dust, so be sure to brush away thoroughly. Now you're ready to use the anchor nail. Keep nailing until it is fully rooted in the board. On some nails, you can space out the anchor nail to where you can place the studs over the anchor spot so they are not visible.

When all the bottom sill plates are fixed in, measure out the bases 16 inches at a time with pencil markings. With a leveler and straight edge tool, nail the top plate to the ceiling. Take the studs and nail them between the bottom and top plates. After this, nail the wood to the top of the studs, which will be your top plate. For any doors, you'll simply cut the bottom sill plate with the right measurements.

If you chose to build the frame without nailing in the base, you'll have lift the wall frame to in the ceiling to get in position. If possible, get someone to help you. Once they screwed at the time and bottom, install the drywall panels. Use one screw in the middle of drywall and go back to install additional screws 16 inches apart.

For any gaps between the drywall, use joint compound and drywall tape and allow it to dry. Use a second coat of compound the next day, let it dry and then do the same on the third day.

When all is done, you can sand out and paint.
