9. The Cozy A-Frame Christmas Cabin
An A-frame is one of those shapes that just looks like winter. Steep roof all the way to the ground, a big triangle window at the front, and snow sliding off the sides.
Build the frame from dark oak, fill the front with glass panes, and put the fireplace right where you can see it from outside. Inside, a loft bed up top and a tiny living area below is all you need. It feels modern and cozy at the same time, which is a hard combo to pull off.
