Ripping out all the crappy paneling and shitty low ceilings in the four small rooms that make up half of a house I bought recently. So, instead of rooms that are 5-10 square meters each, it will be one 30 square meter room open front to back to let all of the sun in. Going to leave all the beams exposed. Little bit harder to heat, but that's not such a big issue. That crappy kitchen stuck in the back corner gotta go soon, too.
