The size of the house may not really matter, but how happy the home is.
Absolutely correct content & I totally agree with you @javybar. If we need to happiness our home, not only needed money. Money can't give happy access. I suggest, every free time go out from home for dinner, travel vacation with family. Other once know, you're loved to family. Also take every dinner one table with family. I know every persons busy with working. But show your love to family members. Then happen happiness to our family.
Wise happy words my friend, Love in the family is always the answer for a happy home :)
