No progress to speak of, but as soon as the weather lifts, I'll be at it full steam. Picked up a couple of nice windows from a buddy of mine that had a couple left over from a renovation several years ago. One will go in the sleeping loft, the other will go along the Northeast wall. I need a fixed window that will go on the end facing the pond (over french doors), and a small window to go in the kitchen/bath area.
I scored a bunch of wood off of Craigslist this morning. It is quarter sawn red oak that a guy cut to use for fencing. I bought all he had (109 pieces of 1"X6" - 8' long). I put a piece on my table saw and halved it vertically. It takes a pass through the saw, then I flip it and complete the cut (can't cut 6" wood vertically). It taxes the saw a bit, but doubles the square footage I can get out of each board. My intention is to use it to cover the interior walls and ceiling. The wood was cheap (about $2.75 a piece), but there will be quite a bit of labor to cut it. I think the end product will look awesome though.
I've also been thinking about stair design. I'm trying to incorporate some sort of storage into them. I'm currently looking at an 8" rise over 8" treads - steep and shallow, but much easier to navigate than a ladder.
Another new idea is the location of the bathroom. I haven't even sketched it out yet, but I'm thinking of placing it in the back corner, which should be a good use of space. I need to work out the details to see if it will work well there. The bathroom will be just a toilet. I have done a bunch of research, and I think we're going with a Laveo Dry Flush toilet. It is electric (with a solar option), and uses vacuum technology to seal and bag your "deposits". It's far less maintenance than a composting toilet, and less than half the price.
