A good question regarding CNC. Yes, it is noisy isn't it... I think my options would be to do it seldom, or to soundproof it somehow, yes. One issue is that half of the garage will be used to park a car (a bigger car than the one shown) so my space really is at a premium. I hope to at least get a small CNC machine one day though. X-Carve may be the answer.

Thank you for your thoughts.
