I've been in a few of my 6000 ft dream homes (sunday open houses). I didn't find they were too big to clean either--lol. We could just shut doors of rooms we don't want to dirty up.
I stay pretty content with each home I've owned (mortgaged). I'm completely satisfied now with 4 bedrooms plus a bonus, 2 living rooms, 2.5 bathrooms minimum, light and bright, dark wood in kitchen, high ceilings and the MUST have is a bedroom with vaulted ceiling, fireplace, a BIG tub in addition to shower. I have all these with my house now, but what I don't have that I want is a YARD! We have an itty-bitty triangular yard. We got the runt lot. I also would love to have either one level or a home that you don't have to enter below the house to get up to the main floor. Good excersize though and that's what we get for a view (of really other roof tops that get the better view--lol).
Here is a plan that isn't really any different from our size home now but I loved the layout. Seemed resort-like.
