Living LARGE In A small Space

A family of 6 can comfortably live in 600 square feet. I never would have believed it over a year ago, when I was enjoying a good 2000 square feet with a triple garage and a big backyard. But this year I've experienced it. The key for us has been paring possessions, creating comfy corners, and getting out :)
We've lived in an apartment in our church for over a year. It is, as you've already guessed, approximately 600 feet. It has a galley kitchen, bathroom, small living room, and two bedrooms.
I frequently go through our things and donate what we don't need or use, have outgrown or just isn't working for us.
Having storage in other parts of the church has been extremely helpful and I store what we don't need now but may want later.
We have coat hooks, one closet, a trunk, a shoe organizer, and a basket full of winter hats and gloves on the landing (our "mud room"). Just inside the door is my desk, my station for writing letters, occasionally reading (which I do anywhere), journaling, computer stuff.
The kids have baskets and tubs to help them stay somewhat organized, including some which fit under the bed. Their room is the biggest and has only their bunks, so they enjoy the corners and the space under the "L" of their triple bunkbed, which gives them special spots for play. The baby has a rolling pack and play that resides in our room until we're ready to go to bed, when it moves to the kitchen. We opted to put a dresser in the living room for the much needed storage and one comfy couch and a wing chair that can can look out to the living room area or shift to the banquette which fits neatly in the corner next to the fridge. The trunk coffee table is an antique and great for storage, games, running cars back and forth, etc. It gets a lot of use and gets moved around a lot. Virtually all the furniture is relatively small and moveable.
Ern and my bedroom is little more than a bed up against the wall and just a space by the dresser but it's nice to have our own space.
We go on walks when we can or just head to a mall or grocery store to get out when the small space is too much. We're thankful for the church fellowship room in the basement where we occasionally play a game of tag the kids call "turtles." It's so cold and snowy for so many months here in Edmonton, AB, that that basement space has really meant a lot to us.
It's been fun, but I can't say we aren't looking forward to moving out to bigger quarters! And there are many times when the whole place is a mess and most of the time some part of it is--the dresser in our room especially gets piled up and toys are frequently strewn around. But it's not impossible to live relatively comfortably in a small space.
