How to Build a Wall Around a Small Stairway Railing

Framework Concerns

• Assessing the surrounding wall framing is important. Adding a new framework requires working with a structure that's already in place. Use a stud finder to locate the framework in the wall below the stairway. You might need to design framing for the new short wall that's strongly attached to the wall framing beneath the steps.

Wall Dimensions

• Draw a plan for the new wall, determining all of its dimensions. Envision the wall as blending perfectly with the room's walls, which will likely be covered with drywall. The width of the wall will define the size of the framing boards. Build the wall approximately 8 inches wide at minimum to create a strong structure. A flimsy wall that will substitute for stair railings might give way if someone leans against it. Plan to build the wall about 30 inches high.

Old Railings

• Remove the stairway railing to build the wall. Gently pry up old railings and balusters with a crowbar, taking care not to injure the wooden steps. Take up any carpet that's underfoot as well. You want to build the wall on the flat surface of the floor, so the framing is well attached to the floor joists.

Basic Framework Design

• Attaching a new framework with screws will add strength. Use an electric screwdriver and 4-inch wood screws to attach the basic framing of the new wall. You must install the floor boards first. The wall framing will be built with a bottom plate section, short studs on 16-inch centers and a top plate.

Drywall Installation

• This wall structure will need drywall covering and finishing techniques. Place drywall type over the seams, then cover it with joint compound.

Finish Work and Trim

• Wood molding, trim and handrail materials are required. Depending on the wall design, you may need to install baseboard material or heavy molding along the wall's interior next to the steps. To preserve the drywall finish, the stepping areas near the drywall will need a protective wooden border of some type. Smooth wood boards can fit on top of the wall space for handrail material. Stain the wood to match the room's surrounding molding or cabinets.

Replacement Flooring

• You may need to add new flooring material on the steps, if you’ve removed it. Install carpet or tiles, for example. You want the wall to look original to the design of the steps, not built on later, so use flooring that ties everything together.
