Then consider painting the entire wall one color…Just afraid it might look “too dining room”. I like this color for the walls…B.M.smoke embers…from your photo, the wood tone has a gray undertone in the brown finish. Pottery Barn

So I just tweeked your current plan a little bit by doing pier style cabinets on either side of the bed. Then you don’t have to have a nightstand. Or you can just do full height wardrobes. You will have to account for the jogs in the wall so that the bed is positioned so that you can get the doors open. Then the desk would be opposite the bed and possibly add a little bookcase. I am showing a queen sized bed.

Yikes! I didn't know that about pop-up trundles. Good to know so as to avoid them. I wonder if there are different quality ones that might be better? The day bed looks like it might work for kids, but I would hate to be the person in the back who would be up against a wall and have to climb out over the front person. eta: I looked again and it looks like it can be designed so there is no back on it, which might work perfectly, so you can have it away from the wall for access from both sides.

M B, I almost wrote the same thing earlier this morning about the narrow lot comment. A 100 ft wide house likely sits on a 120 ft or 130 ft lot, which is pretty generous considering the typical suburban lot around here. We live on a 136 ft wide lot, and granted our house is only 65 feet wide, but on the driveway side there is enough space between our house and our neighbor to squeeze in another house! Our last house was on a 50 ft wide corner lot, meaning we had a 15 ft setback on the side street (and 5 ft setback on the other side lot line). Now that is narrow! One challenge for any plan is going to be balancing the 3 stall front facing garage with the rest of the house. Ideally the garage is setback at least slightly from the main body of the house. But if a plan like the one that the builder provided had another garage stall added, it would really start to set the house out of balance. Better to be designing with the 3 stall garage in mind from the start.
