I moved in October 2012, just in time for the Minnesota winter and hands down the number one question I am asked is: "Are you staying warm in there?"
I don't know what people think I'm doing out here, shivering over a single candle? The answer is YES, of course! It's 117 square feet with cutting edge insulation tech. I have one built in electric heater in the bathroom, and one ceramic element space heater. I have it set to 60 during the day and 55 at night because it's always warmer in the loft. It's no trouble at all keeping it warm.
The biggest problem so far is keeping the floor clean. Muck boots covered in snow make a mess every single day. Take two steps in the door and you're halfway through my kitchen/living room. The closets are too small for my boot tray so I've improvised with a plastic place mat and rags underneath. I also have a rag that I use to wipe up the floor after I come in. It's worked great so far, but I'm looking forward to spring when I can build the porch and keep my boots out there.
