Hmmmm... for a quick response.
1. Walk out basement would be some type of fun activity room, casual furniture, ability to roll out a ping pong table, maybe even a vintage type pong game or similar. Sink and bathroom of course, not so sure about a formal bar but maybe someplace for refreshments, also if room, a really nice size large TV and proper sound system.
2. Main Floor entry needs to be two stories high or better said 16 foot ceilings in the foyer with a large 6'x6' curved top window above the entry door and then will lead straight into the great room with same 16 foot ceilings that continues with a nice smooth flow. IN that room will be two rows of windows 3 or more in each row with the center window in each row being another 6'x6' solid/non opening window. Also in the foyer is the staircase to the second floor, first 4 or five steps wraps around the drywall between the dining room, then a small landing and then roughly a dozen steps to the second floor landing.
A-Back to the entry foyer, when coming in the front door the dining room with lower ceilings will be on your right, you will be able to walk through the dining room right into the kitchen. From the foyer to your left will be a half bath.
B- Back to the great room, there will be a large arched entrance to the Kitchen as well. Kitchen ceilings will be the same height as the dining room, lets say 9 feet?
C- From the kitchen you will be able to continue to walk right into a Sunroom built the same as and part of the house (not an add on) with a back door. The sunroom will be the same dimensions wide as the kitchen with a large opening to walk through. Lets say 12 x 15 feet. 6 sets of double hung windows or windows of your choice with a back door leading to a deck or whatever.
D- back to the great room, walking the other direction you will be able to walk into the MAIN FLOOR Master Bedroom right off the Great Room. It will have a pushed up tray/trey(?) ceiling in the center with hung fan, a tray ceiling angled at the edges (sloped), instead of straight up which is kind of a "hard look" Ceiling will be roughly 10 feet high.
Of course the master suite will have a double door with master bath (10 foot ceilings), double vanity sink, stand up shower and tub, walk in closet.
3. Second floor will have 4 bedrooms with standard 8 or 9 foot ceilings, one full bath (option is a second but... whatever) 3 bedrooms will be grouped together at the top of the staircase landing, from that landing on the side with the 3 bedrooms and full bath will be a 55 inch wide catwalk that connects the 4th second floor bedroom (also a perfect office if needed) The cat walk will be open on both sides, with white spindles and oak top railing and cross right through the 16 foot high great room and 16 foot high foyer. Its a great look and one that will get compliments. This 4th bedroom is actually above the master and master bath, good size room only 8 foot ceiling (sloped on both sides) as you need a 6 inch small step up into the room to account for the higher ceiling of the lower master and also for HVAC ductwork ect.
Wow... this took me longer then I thought to type *LOL*
