Do you plan to use the 3rd bay in the garage for every day parking or is it more for storage or for a car with more occasional use? If the latter you could consider doing a tandem garage on one side. If you want a front facing garage I would try to set it back some so it isn't the thing you see sticking out first. Although frankly when you are on wider lots or acreage you often see the side facing garage just as much if not even more than the front facing ones so I don't think in those cases that a side facing does nearly the same for a house as it does on a narrower lot, where it doesn't become as visible from the street. Our neighborhood have many side facing garages including ours, and I see those garages and sides of houses a whole lot more than I see the front of the houses as I'm driving by or even as I'm out running I see the sides more than the front. I actually wish I had thought about that and changed it to a front facing that was set back a little instead as it would have worked better with house access from the drive way etc. Only the houses that are placed along a curved part of the road do I see less of the garage. One has it on the side, but in the way back and still attached and that one you do see a little less of it than the majority that have them to the front side.

Does the bath have an exterior wall? If so you can duct right out the wall. Yes, it means cutting through the stucco and stone, but a good contractor can easily do that.

Plan the supporting pillars with this in mind: If you create a weather resistant flooring beneath your home -- either by adding paving stones or extending your wooden dock/deck that begins at waters edge all the way beneath the full length of your house -- between the new pillars, you could create a very attractive and useful screened porch beneath your home. The downstairs "siding" materials would be the brick or stone over the core material of the pillars (metal posts and/or concrete blocks) that lift and support the home and screen. You could add sliding barn style screen doors to all four garage door sized openings. https://i.pinimg.com/236x/a0/62/1c/a0621c93363cefab531221a9d16a74b4--screened-barn-doors-screened-in-porch-decorating-ideas-small.jpg or doors more like this on each end: https://i.pinimg.com/originals/5f/b4/28/5fb428b9add11e9cd31deb56d1ee2296.jpg Whether or not you add sliding style solid doors inside that ground floor space depends upon how secure you want/need the space to be, especially when you're not there. In lieu of that narrower deck along the sides for what will be the middle floor, you could add a narrow covered porch, with a roof dividing the middle and upper floor on at least one side and have it wrap around the water's edge side. A flat roof on the porch on the middle floor could serve as a deck for the upper floor. Local building codes permitting, you could use a swimming pool ladder rather than traditional wood deck steps to access the porch and you might also consider adding a sliding board from the porch on the middle level to get you to ground level. You could continue using the same brick or stone that face the pillars of the ground floor as your exterior siding for the middle floor (or perhaps only to the bottom of the windows) and then use wood siding for the upper floor w/shake/siding for the gable ends above the upper floor. You could use traditional beach colors of gray or blue white for the upper exterior siding color.

Anj_p - thank you for your detailed notes. BR 1 is tiny. Those are bifolds in the closet door to maximize the usability of a reach-in closet. BR 2 is an odd shape, agreed. Originally the architect had the closet on the wall that is shared with the bathroom. I had them move it because there wasn’t enough clearance any where you put the bed (including this note in case you think that was a better placement). I’m a fanatic about symmetry though, and once we moved the closet, it meant the windows were off-centered which is why I had them put built-ins in the jut-out to balance the room. The windows are 4 ft windows though, so I don’t think a bed will block the light... but maybe I’m wrong. BR 3 will have a built-in in the weird corner - I should have noted that in the plans. Master - I agree on the walk. I plan to have another child in this house and I cannot fathom doing this walk 47x in the middle of the night. However, my husband gets up very early (~4:30 am) and says he would like to use the shower in the morning without fear of waking me... Additionally, the kitchen is right below the master bath right now so I think this placement was chosen for easy plumbing. I had tried to swing the master around - put the WIC where the hall bath is and then shift the Master Bath to where all the closets are and my husband hated it... That being said, I wanted to come here to see if a lot of other people share this opinion. I think right now he is comparing my thoughts (novice, never built a home) to those of a professional architect and builder and thinking there is no way I can come up with a preferable layout. He might be right, but I figured it’s definitely worth checking! Thank you for all the other notes as well. I will keep this all in mind.
