I don't mind a spacious house since i love solitude and my own private study and at times entertain people in the house. Normally i would have guests who come to stay for short visits too. But i have known the life 'without much' and fitting in a 900 sq ft house/apartment is not too hard providing everyone respects each other's space. Now i imagine.. 900 sq ft. It would be too small for my taste but it is possible to accommodate all 6 persons in my family(excluding the regular relatives visits). If i were to put three young girls in the master room and the other room for the only boy and another for a teenage girl. I would be sleeping on a sofa bed in the living room which is more than fine with me(used to sleeping on the sofa since young). Surrounded by my books. Clothing can be kept in either one of the girl's rooms. The house must have two bathrooms and a wet kitchen out. A small porch/balcony to with stools or bench to sit and sip a mug of hot black coffee in the early morning coolness or watch the night view, after dinner. Hey, this isn't bad at all.
It's interesting to just think about!
