Master bath is completely unusable. Kitchen has a barrier island that you will walk yourself to death trying to work in it. The hall between the utility room and powder room is wasted space and should be rearranged to incorporate the space into the laundry or pantry.

The study would be very awkward used as a bedroon, even a guest room. I'd swap it and the entrance so it would have closer acces to the bath. In addition, that would give a better sense of spaciousness because of the vista through the home straight to and through the doors to the porch.

The bumpout in the master is awkward and doesn't serve any real purpose. It is to small to have as a seating nook. It needs to be eliminated, or else become large enough for an actual purpose. Like that seating area. Or as a niche for the head of the bed. In addition, the bathroom area shoud be used as a sound buffer between the bedrooms and other areas.

Swapping the bed and bath would allow the bedroom to have windows and light on two sides instead of wasting that on a room so seldom used. With the two flipped, that awkward little bumpout coud be on the rear as a bay window seating nook. And the bath could still have a bumpout for the tub, and the architecture would now make sense.
