The bathroom is too big? I find it too small, there's no space left for storage for towels, etc. It's probably due to the popular space-consuming T. I would probably leave out the T, arrange it differently, and then put the washing machine + dryer at the top of the bathroom, so you have some storage space in the utility room. And I think it's more sensible to do laundry where it accumulates; that's the only point we couldn't implement here anyway. I would also keep the garage. The room layout is otherwise good, the staircase wouldn't be my choice (but it doesn't have to be).
