Thank you!
Couple of updates:
- I did add bracing and spray foamed the gaps around the stairs. As AggieTaco mentioned, I think the bracing helped more than the foam, but I wouldn't discount the foam entirely. It did help in some areas where big cracks were present. Bracing will make it easy to install the drywall on the ceiling when that part comes.
- Got lighting installed. Went with four can lights. I found an Halo gimbal product that is meant to go in a can, but allows for really good pivot angles and plays well with a dimmer. Hard to get a pic that doesn't fisheye, but the spacing is perfect. I spot checked with a few books at several locations with many of the boxes, and you can read the spines really well.
So they do put a lot of light out, but I picked the quantity to spread them out and reduce shadows. To this end, think the quantity and locations are perfect, and I think once the cabinets are stained and the dark flooring is in place, it will reduce the brightness, but I went ahead and put a dimmer in the box that's on the front wall, just to manage the brightness if it's too much. Easy to do now.
- Also installed the extra bottom plates - went with non-treated.
Next steps
- Still need to build two more boxes, and I think I've worked out some of the finer details
- I decided to go ahead and stain outside of the closet. Once the boxes are built, will stain them
- I think once I pull everything out, I'll go ahead and install the tile. There are definite benefits to doing later, but I think it'll be much easier with the boxes out and having just a little more room to move around.
