Mstr bdrm trayed ceiling & 2 walk-in closets (make into one). Great room with vaulted ceiling, fireplace flanked with built-in shelves. Laundry room, kitchen pantry, two covered porches (make kitchen and dinning space bigger)
Floor 1 - I would take out one of the bathrooms between the bedrooms and the wall for a Jack and Jill bathroom. Also needs a big shower in master bath, and not crazy about the master suite sharing a wall with the living room.
But on a smaller scale. Architectural Designs House Plan - "One Level Living Plus" - gives you over square feet of living plus a lanai that opens to the living room by collapsing the back wall. Ready when you are. Where do YOU want to build?
Architectural Designs House Plan has an open floor plan and indoor/outdoor living with the back wall of the great room collapsing creating an enormous continuous space that flows to include the covered lanai - and pool if you build one - together
