Nice feedback
Sloth,
You have a good eye and sense of place. This plan is designed to take advantage of the sloping lot and ocean views (off the lanai's which face west). Afternoon glare will be more of an issue in the living room and kitchen/dining room.
The windows you speak of in the family room and bedroom#4 won't actually be there. It's incorrectly shown on the floor plan.
This is something I put together to show the finished elevations I'm looking at. The idea is to have the garage at sidewalk level.
Thanks for reminding me about the master bedroom and lack of wall space. I do have to discuss that with the architect. There are places in the house I could get rid of a few windows, save some money, and gain some wall space. The living room is another candidate I'm probably just looking at the neighbors.
As you said, 'X' represents a stand up shower. Thought about using tile to make a built in seat.
