The new house we are moving too has about 20 foot ceilings all throughout the first floor and entrance. We are wanting to add a wall for this, with a traditional top rope set up. Will have it so you can rope solo, or traditional belay. Lots of posts about small bouldering caves but any past threads/advice for walls? I figure do “studs” to the drywall then sheet it as normal but anything I’m missing. Any advice for the top or anchor? Or should we just use some chains and a steel carabiner?
20' do you REALLY need a toprope? I have been to a few gyms with 18-20' high walls and they had these INSANELY BIG pads that were cushioned but also filled with air, so when you landed on them they made a POOOOSHHTT sound. It was rad to climb that high without a rope. Maybe look into those. Toproping on 20' sounds miserable.
PS "studs to the drywall" - WTF!?!?!? You need to frame the wall (so its angled off the existing wall then tie it into the existing load-bearing frame). This may require an engineer to do safely if you do not have construction experience, but no you do not "do studs to the drywall" lol :D
"Or should we just use some chains and a steel carabiner? "
into WHAT? We put bolts and chains at the end of sport routes into ROCK. I doubt you have steel beams in your house, but this is probably what it would require. Even lag bolting through laminated beam I doubt you could convince me that it would be safe long-term with repeated wear/tear from multiple falls on the wood.
Your idea has tragedy written all over it tbh man, the questions you are asking mean you are not ready to design something like this for yourself.
