Of course every garage varies so my design probably couldn't be copied exactly but hopefully showing how I did will show all the basic concepts behind building a wall and give you a good idea on how to go about this large undertaking should you choose to do so. The total cost of the project was under $400 (that includes holds so if you made your own holds it would be ~220$) and is well worth the investment. An added bonus is the wall has a door that can be opened so it doubles as extra storage space. (or if you dont need storage space but have kids (or you're a kid yourself) you could use the inside as a pretty awesome fort). It really is up to your imagination. But without further adieu we will delve into the finer details of climbing wall design & construction.
Step 1: Brainstorm
After brainstorming I compiled a list of the things I NEEDED my wall to have:
-Large 45 degree overhang for the main climbing area, to be used for strength and endurance training.
-Smaller 90 degree overhang for super intense workouts.
-25 degree lead out from the 90 degree that i could mount a Jacobs ladder to for finger strength training
-A pull up bar
-Access to the inside
And a list of things i WANTED to have:
-A vertical wall just for fun
-A variable angle part
-Some sort of bulge
-Anchors at the top to belay small children
I also instituted a budget of $500 that I didn't want to exceed.
You take all your requirements then go on the the next step DESIGN where you put all this together to make the best wall possible that meets as many of your constraints as possible
