Building a rock climbing wall?

Question:A couple of my friends and I are interested in building a rock wall of our own right outside my house. Instead of going out and buying a truckload of 2X4's and dozens of sheets of expensive plywood, however, we were hoping to build it right onto my house.
I understand that this is highly unorthodox, but financially, it just makes sense! Why go out and buy all of the materials listed above when you can save a significant amount of money by simply using what you have available?

Our plan is to go to a local sporting goods store (ie- REI) and purchase a large quantity of hand holds and bolts. Then, come home and attatch those hand holds to the outside of my house (I live in a brick house, so the holds would be bolted right onto the brick).


My question is: when I attempt to climb my newly built wall, will I compromise either the structural integrity of my home or pull out/damage any of the bricks which I climb on?

Thanks!

Answers:
Navy, Semper Fi, sure, just make sure you use concrete screws and long ones at that. But, think about this. If some kids get in your yard and fall off the thing you are liable. The only way you would damage the brick is if it is old and easily cracks when you put the hand holds up. Also old houses don't have good mortar between the bricks. It gets old too. Hey man you asked.
