Even those of us with easy access to quality boulders and crags often find ourselves wanting. Sometime weather shuts us down, and sometimes we just want to train in a more structured way than we typically can on granite or limestone. Even if you have a climbing gym nearby, nothing beats a home climbing wall when it comes to getting strong. No crowds, no kids birthday parties, no membership feesjust you and the woody and a desire to be bone-crushingly strong when spring hits.
You can build a woody just about anywhere. Back in the day I built a free-standing wall on the tiny porch hanging off of my tiny apartment. Several years later I built a wall in the corner of my garage. My most recent experiment, however, proved to be the best option. First you need a girlfriend with an unfinished room in the basement of her house. Why the girlfriend, and why the basement? Its a lot cheaper to split the material cost with someone else, and the basement is more comfortable than the garage. PLAN
Now that you have a location, you need a plan. The easiest, and generally best, plan is to build a 45-degree overhanging wall thats 8 feet wide and runs floor to ceiling. This is steep enough to give you a good pump, gives you enough area to set some real problems, and keeps the math nice and simple.
Build your own bouldering wall
You dont need to be a master carpenter, but you do need a few basic tools:
Safety glasses MATERIALS
Materials will change based on the size of your wall. This is the list for a basic 45-degree, 8-foot-wide wall.
12 Joist hangers
3 10-foot 2×6 boards
2 8-foot 2×6 boards
2 8-foot 2×4 boards
3 4×8-foot ACX plywood
1 Box 3.5-inch screws
1 Box 2-inch screws
1 Box 16d nails
~225 3/8-inch T-nuts
Now that you have everything together and know where your wall will go, its time to build. This may look like a lot of steps, but its really pretty straightforward. If you can run a saw without losing a finger, count in increments of eight, and swing a hammer, then you can do this. STEP 1 INSTALLING HEADER JOISTS
Start by screwing header joists (8ft 2×6 boards) to the wall and ceiling. These will mark the bottom and top of your wall. Screw the bottom one in place about a foot above the ground. Measure from the top edge of the bottom board to the ceiling, and then measure out that same distance from the wall across the ceiling. That mark will be the inside edge of your top header joist.
STEP 2 INSTALLING JOIST HANGERS
Top and bottom header joists installed
Place your first joist hanger at the end edge of the bottom board, and hang another every 16 inches until you reach the other end.
STEP 3 PREPARING THE JOISTS
With the joist hangers installed, youre ready to prepare your joists for installation.
Measure from the top edge of the bottom header joist to the wall-side edge of the top header joist (in a straight line). This will be the length of the inside edge of your joists (10ft 2×6 boards). Mark the inside edge of your board, and make a 45-degree cut across the broad side of the boardthis cut will allow the board to sit in the joist hanger. After your initial cut, measure along the edge of the cut 5.5 inches from your initial mark, and make another mark. Flip your board over and, starting from the second mark, make a cut perpendicular to the first onethis cut will make your joists flush with the edges of your header joists. Repeat these cuts on the other end, making sure your first cut on that end starts on the same edge of the board, and then do it all again with the remainder of your boards. STEP 4 ASSEMBLING THE FRAME
Place one end of your joist in the bottom joist hanger, and get a friend to hold it up so the other end is flush against the header joist on the ceiling. Now use a joist hanger to secure the top of the board. Mark your top header joist every 16 inches and repeat the process until all the joists are in place. Your frame is finished.
STEP 5 BUILDING THE KICK-BOARD FRAME
With all the joists installed, your frame is now complete.
Cut some 2x4s short enough to fit vertically underneath your bottom header joist. Start at one end of the header joist and screw a vertical board to each of the studs you find until youre at the other end. This will be the frame for your kick board. STEP 6 INSTALLING THE KICK BOARD
Grab the circular saw and make a cut along one of your pieces of plywood to create a sheet thats 8 feet wide and the same height as the 2x4s you just cut. This will be your kick board. Most people wont put any T-nuts in this board, and choose instead to simply use screw-on footholds here. Add some if you want (as shown in Step 7), and then screw the board over the top of your 2x4s.
STEP 7 MARKING & DRILLING THE GRID
Installing the Kick Board
Now comes time to install the T-nuts in your remaining sheets. There are a few ways to go here, and there are pros and cons to each.
Random holes (natural feel but easy to leave large gaps)
8-inch grid (easy math but restricts problem-setting a bit)
8-inch staggered grid (a little more math, but a natural feel without gaps)
For the staggered grid method, measure along the short side of your sheet, and make a mark at 4 inches, then every 8 inches from there. Do the same at the other end, and then snap a chalk line across the sheet to connect your marks. Lay your tape measure along a line, and put an X at 4 inches. From here, continue to mark an X every 8 inches (12, 20, 28, 36, etc). On the next line, simply start at the edge and mark an X every 8 inches (16, 24, 32, 40, etc). On the third line, go back to your original count, and so on.
Once all of the holes for your grid are marked, using a ½-inch drill bit, drill a hole at every X, as shown below.

STEP 8 INSTALLING THE T-NUTS

Flip the board over and hammer the T-nuts in place, making sure theyre installed straight. STEP 9 INSTALLING THE WALL
Have a few friends hold the sheet up against your frame, get out your drill, and screw it in place. Dont be stingy with the screws. This thing has to hold your body weight and then some. STEP 10 SETTING THE HOLDS
The best place to start is with the largest variety set you can get. Some climbers will want more big jugs, and others will need a bunch of tiny pinches to progress, but everyone will need a good selection to get things going. Experienced boulderers will often start with a blank wall and set problems, but the easiest way to get started is to simply spread the holds out and start bolting them in randomly. Once theyre up you can start to tweak, turn, and move holds until it comes together in a way that feels good. Dont be afraid of screw-on footholds. They save money and space, and their only downside is that they leave small screw holes behind when removed.
Dont limit yourself to problems that just go from the bottom to the top. You dont have a whole lot of wall to work with, so try to set some problems that traverse or down-climb. One of the easiest ways to come up with long problems that take advantage of every square foot is to pair up with your training partner and play the stick game. Its pretty simplejust get a motivated partner to point to holds as you climb. You go where they point. Its a great way to get ridiculously pumped.
The key to keeping a home wall fun is change. When it starts to get boring, mix it up. Every once in a while you should strip all the holds and start from scratch. Invite some friends over and have them set problems. Get out your ice tools and scratch the thing up. Buy some new holds. Do whatever it takes to keep things interesting. If you keep it fun and stick to training, youll be ticking off projects left and right when spring hits.
