I have a bit of bare wall above my desk and I wish to utilise the space. Maybe put a couple of shelves up, and hooks and mounts for my game controllers, headphones, microphones, cameras and what not. Maybe put my desktop computer up there as well. The catch is, if I can help it at all, I really don't want to drill it, for various reasons that include:
I don't know what's behind the drywall and my stud finder seems to give very confusing readings. There might be pipes, electric wires and what not. Also, I can't seem to find studs. Either there are no studs or they're in weird bendy shapes.
Behind the drywall is a concrete wall that I don't want to drill into because it's shared with my neighbour (these houses are terraced houses) and I don't want to accidentally do something wrong and piss my neighbour off and even get sued.
I'm cripplingly indecisive and I get an anxiety attack even just thinking about where I might permanently drill into my beautiful house and then possibly change my mind about where to place my furniture.
So an idea I had is to stick big slabs of wood onto the wall, something like these, using very strong double-sided tape, something like this. My hope is that the strength of adhesion is proportional to the total area of sticky tape used. Is that even true? If it is, then it means that I can just use an absolute truckload of sticky tape to stick the slab(s) of wood onto the wall so strongly that it would support even my body weight, and then I can screw or nail whatever other things (hooks, mounts, and even shelves) onto the slab(s) of wood instead of directly into the wall. Might this idea be feasible?
Any other ideas for mounting shelves and other things onto a wall without drilling?
