OP - I haven't read through all the pp, but I wanted to tell you that I grew up in a home like this - you walk in and you have to go up or down. I didn't even notice it growing up - it's just how out house was, but looking back as an adult, here are my thoughts:
PROS:
We lived mostly on the top level -it had 3 bedrooms, 2 baths (master bath had stand up shower only, the other bathroom had a full tub), kitchen, dining room and formal living room. If we watched tv, we did it in our rooms or all piled into my parents room.
Privacy for guests - when people stayed with us, they were able to maintain a large level of privacy, as the guest rooms were downstairs. There was also a full bath down there (stand-up shower stall).
Basement was total recreation area - this area was WONDERFUL when I was a kid. I could have friends over and it was huge and we could run and play and whatever. It was open to upstairs, so parents could keep an eye on what was going on.
Jacuzzi room! - my parents built onto the back of the house - so when you walked in the front door, you could go straight out of the foyer through another door - into what my parents made into a large jacuzzi room. We had an indoor 8 person hot tub on a raised platform, cedar lined walls, a bar, and full sized fridge. It also led out to a large deck in the back yard. It was great for entertaining, which my parents did a LOT. That room was wider than a 2 car garage, and at least 2x as long. We had to walk through it to get from the garage to the house.
The Foyer - When you walked in the house, there was a small landing that we called the foyer. It had small tiles and had the front door and windows on one wall, the stairs going up and down on another wall, and straight ahead (when walking in) was another door and a coat closet. Perfect for us. When we had company over, shoes always stayed in the foyer. When a lot of people came over, it was piles of shoes everywhere! There was also a ledge in the foyer that was perfect for keys - all keys were put there on a daily basis. It was just where they went.
CONS:
If you don't have carpeting, it's gonna be loud. Everywhere. Bathrooms and kitchen had linoleum, but everything else was carpeted. Stairs had runners. My parents switched to ceramic tile and hardwood/laminate wood and everything echos.
When having a party, it seems very split, as only the formal living space was upstairs. For superbowl parties, birthday parties, etc, had to bring all food, drink, etc from upstairs to a table we'd set up downstairs, and then try to keep food in the downstairs area.
When I was a teen, and my boyfriend was over and we were watching tv or a movie, my parents would be in their room if they wanted to watch something on their own. That was in the back of the house on a different floor. Use your imagination.
Aw, now I miss that house. My parents moved out of it a year ago when my dad was diagnosed with Alzheimers. It went through extensive remodeling (hello early 1980's!) and is on the market.
