For a setting, I want something like that Falling Water house.
It's a freaking *house* built over a freaking *waterfall.* Can you get more amazing? I didn't think so. The water runs through the actual house, not just under it.
My dream house is two stories, with lots of glass and big open rooms. The two stories have a balcony inside instead of a totally flat ceiling, meaning the center of the house cathedrals up to the second floor. It has lighting sliders so you can make the atmosphere whatever you really want, including changing the tone from cold to warm light, and it has a big patio with a hot tub. This is essential. Also a fireplace indoors, because hell if I'm living in a house without a fireplace. There is a spiral staircase from the first floor to the second. The outside is predominantly either stone with big glass windows or wood with big glass windows. The living room has an LED setup that makes it good for bitchin' parties.
Must be by a lake that has enough carp and whatever else to eat that stupid lake grass. A big lake, one you can waterski in. Has all the amenities of a nice modern lifestyle -- good internet connection, nice TV, gaming consoles, good computer system, all that. Also has speakers throughout the house that link up to a central sound system. One that has enough bass to shake the building. Aw yeah.
The bathrooms are marble, pretty spacious, with large deep tubs. There are three bedrooms, two of which are for guests and one of which is for me. There is a study on the second floor that is large and hosts all my crafting supplies and artwork and so on. The kitchen is big and tricked out, with a nice gas range, good oven (that vents to the outside, dammit, have you ever botched up a self-clean, that sucks), a bunch of kitchen equipment, a stand mixer, and all that. The kitchen joins to the living room by a wall with open windows, so that people in there can talk to people in the living room.
