A friend of mine once asked Rav Wolbe ztl years ago if he should move to a larger apartment (in EY) .
The answer he got was if you cant do Hachnosas Orchim at present, you should move!
PS CTL I am 10 years younger than my brother and we shared a room. It wasnt good for either of us. I agree with you . There are plenty of other opportunities in a home for family bonding and respect lessons.
