I LOVE a house with a wrap around porch. The balcony on top is not necessary, but it is nice if I had a two story. I would love for it to be out in the country (but w/in easy driving distance of the city, as I'm now spoiled to the each accessibility of everything in the city. )
And I definitely second that Maddie...I'd probably only want it in reality if I had a maid service and a caretaker that came to groom the yard. Otherwise it could quickly get pretty ugly.
ETA: Right now my dream house contains one major necessity: a LARGE kitchen!! No more apt style kitchens!!
