My husband, myself, and our then-kitten lived for two years in a 600 sq. ft. apartment, which I loved. It had the bedroom on a corner, so it was always sunny and bright and felt very open. Didn't care a whole lot for the kitchen and laundry room/pantry...but it was acceptable...and the main living room and bathroom did not feel cramped.
We decided that we "needed" a house and started the hunt...and moved into our 1,600 sq. ft. home with a small backyard when I was four months pregnant. It's a three bedroom, two bath, two car garage house with a small attic and a bonus room we use as our office. It's a very nice house and feels very open. When we bought it we could see ourselves raising our kids here...as we never planned to have more than three and should we have needed to once kids reached the teen years and all wanted their own space we could have converted the office to a fourth bedroom since my husband is in the drywall and plastering business. It is PLENTY big for us...really too big...since we never use the third bedroom except for occasional company and really don't spend much time in the office...and since it seems we may end up with just two kids (after some scary stuff and big medical bills surrounding the birth of our first) we would never grow out of our space.
But funnily enough, we are actually looking forward to the time when we can put this house on the market and move to a space of about 330 sq. ft.!! Yep, we are gonna buy a
fifth-wheel and hit the road sometime in the next 2-4 years!! Crazily enough, I'm actually looking forward to being in an even smaller space than we were in when we were in our apartment!! The layout of the living/dining/kitchen area is snug, but not claustrophobic, it will actually have 1.5 bathrooms, the kids room will have an entertainment center/wardrobe and two sets of bunkbeds and a huge open floor space (at least as much as Bug's room has now), and the master is big enough for a king sized bed and room to walk around it comfortably!! Who really needs more than that? If our second child ends up being a girl then at some point down the road we may install a curtain to divide the bunkroom for privacy...but truthfully, except for dressing what prepubescent child really needs an exclusively gender divided room?
I just think back to the time my childhood family lived in a trailer of only 192 sq. ft....where the couch became a bed for my sister and I, a curtain divided the back bedroom from the front room, my two brothers slept in a bunk over my parents double bed, and somehow another sister was conceived without any child seeing and having psychological scars!! If my childhood family of six (and then seven) could handle three years in less than 200 sq. ft....I am POSITIVE that my husband and I and two or three children can handle 330 sq. ft. with no problem!! :-D
