Being single,
My last apartment was 680 sqft. That was just about perfect for my needs. No empty space, no clutter. My one wish was that I had a bigger kitchen, since despite not being much a cook I love to experiment.
About two years ago, I bought a condo (based mostly on “the price was really good” rather than “I needed to move.”)
Honestly, it’s too big for me at about 1500 sqft. One bedroom (painted like a nursery) still has unpacked boxes from the move, two years ago. One of these days I’ll get motivated and just throw the stuff in their out, but since move-in it’s pretty much just been sealed off as an empty room.
The living room is about right. Room for a couch, a loveseat, a fireplace, a nice reading chair and the TV.
I’ve got another empty space - “the study”. It’s connected to the dining room, has a faux hardwood floor, and nothing in it but a ratty couch that I haven’t sat on since I moved in.
Bedroom is OK, though I need more bedroom furniture. Right now I just have the bed (queen), two nightstands, a dresser and a few lamps. A lot of empty space.
Two full baths - again, overkill. I use the bath off the master bedroom daily; the other one I’ll use the toilet but have only used the bath/shower once.
“Nook” area off the living room. Perfect for my computer desk and compy. That’s where I’m sitting right now. A bit of shelving which is good for books and discs.
Short answer, I’m probably not using about 40% of my living area. I really should find a girlfriend and have her move in, LOL.
But I’m not complaining. The price I got for this place was great.
