Mine would be brick -- I love brick -- with a couple of levels,a big airy modern kitchen, a traditional English garden including lots of roses and lilacs and violets, a pool, and a hot tub. And a view of water, whether brook, over , lake or ocean all being fine with me.

Split level ranch, with a cozy rec room in the basement with a bar.

A FLW Prairie Home, set in woodland. A big, open kitchen/living room, a cosier sitting room, a study/office, lots of storage (I hate clutter), three or four big bedrooms all with their own bathrooms, a laundry room, an attached garage. Big windows, a wide, wrap-around deck, a herb and vegetable garden (tended by someone else) and, as a last indulgence, a covered walkway to a gym and heated indoor pool, plus sauna, steam room and showers.

A mid-century ranch house in the Eichler/Neutra style. My brother has now renovated two houses like this in Arizona (here's one). His have been on the lower end though. Some of the fancier ones have beautiful sloped roofs like this and this.

I loved the ranch my parents had in Florida when I was in high school. The house was sort of an L around the pool/screened in porch, and there were sliding glass doors for walls you could open all the way when the weather was nice. I wouldn't want to own a pool because they're a PITA but I liked having a house you could open up for light and fresh air. I suppose that style would be less useful up north, but I can dream.

Comes with a (free) caretaker, gardener, cleaning person, cook, and personal assistant. A brownstone or similar in an urban area. With parking.

Above the floodplain of a country stream, nearest neighbor a mile away, with fast internet.

brick rancher with 4 large bedrooms, 2 bathrooms, all seasons room, large screened porch, med-large kitchen, ton of storage, mosquito spray system plus stewriffic's caretaker/gardener/cleaning person/cook/personal assistant. So essentially my house just bigger + staff.

I don't understand the question?

(I'm from the generation that never has and never will expect to have a house)

Already own my dream home but I'll describe it as if we'd already done all the renovations/restorations planned.

Red brick italianate L-shaped townhouse in a walkable downtown neighborhood where everybody knows your name at the corner cafe. All original 1860s details intact including light fixtures (converted to electricity), doors, windows, hardware, staircases, fireplaces and floors. It's an end unit with a big bay window and lots of side windows so there's a ton of light. A huge side porch runs the whole length of the back of the "L" and leads down to a secluded brick patio with wooden adirondack chairs and a low table.

The house retains it's original victorian floor plan with the front of the house dominated by a three story stair hall and the rooms in the back of the "L" stacked "shotgun" style with no hallways. The back stair case is as plain as the front one is ornate and leads to the room over the kitchen where the Irish maid "Mary" lived when the house was new.

The kitchen is a compromise between history and practicality since we don't want to cook over a coal stove and like having a refrigerator and running hot water. As was the custom, the kitchen is small and can't be opened to the dining room in front of it because the servant staircase is in the way. We have removed most of the interior doors between rooms though to create some feeling of openness.

The floors are the original clear pine that was probably painted originally but we've polished and varnished them with an antique oil varnish that had to be bought in Ohio due to VOC regulations (bad us). We've upgraded the electrical wiring but installed reproductions push-button light switches with brass plates. The house didn't have electricity originally but was probably wired pretty early since it was an upper-middle class area and folks loved to show off.

Perversely, the back of the lot is totally taken up with a "garage" that's as big as the house. I put garage in quotes since it's really more of a small warehouse at almost two thousand square feet with eighteen foot ceilings and giant steel I-beams holding up the roof. The building was added in the twentieth century as the neighborhood was getting less gentry and more industrial so that the third owners could run a small bus company.

Eideteker, move out to the 'burgh. It's not quite as cheap as it used to be but you can still find a decent place for less than $150K.

Longfellow's house in Cambridge MA, though I'd paint it blue or green rather than yellow.

On the Atlantic ocean .. white and grey shingles. Done up in Maine Cottage style, with lots of big open windows, built-in nooks to sit and read, open floor plan, huge kitchen, several guest rooms so that we'd always have lots of room for visitors, outdoor space including a huge pool with a waterslide, shady areas for lounging, and topiary bushes shaped like giraffes, dinosaurs and elephants. A couple of guest houses so that my family could come for long stays and have their own space.

I was 'this' close to building it until things crashed:
Single level
Radiant heated / cooled slab
Solar orientation with properly sized overhangs
structural insulated panel roof & walls
2 bedrooms, kitch with dining and living
greenhouse breezeway attached to efficiency apartment (for Mom / rental)
Enclosed courtyard for garden.

Something like this (but no TV in the central bedroom):

If it's on the beach, I don't care what it looks like.

It would be much easier to just draw!

It's made out of light straw clay. It has a footprint of 16x20. It faces the sun. It's on the lot that me and my partner bought.

The roof is a split single-slope, higher on the side of the house that has the "storage area" (loft). Under the "storage area" is the bathroom and the entryway, and maybe a closet. There's a secret laundry chute from the "storage area" to the top of the closet. The roof over the "storage area" is just a metal roof. The "storage area" has windows that look out from "bed storage" onto the green roof (and these windows also let in morning sun.) You have to go up a ladder to get to the storage area. It also stores a desk and is well-ventilated and has a small pseudo-closet and built-in bookshelves.

The main area of the house is ~16'x13', has a kitchen, good windows, and there's a column in the middle to support the green roof. The roof over the main area is a green roof. There's a rocket stove attached to a raised corner where couches go. There's a kitchen with a peninsula/breakfast bar. There's a sliding door at the end of the kitchen to get to the garden. A greywater system.

Behind the house there's a bike shed. It stores bikes. Haven't figured out the landscaping yet but the walnut and madrone trees are staying, and the non-native invasive norway maple will probably get replaced by a fruit tree.

So far everything has been realistic and will probably actually happen. The part that I want that isn't to code: a compost toilet and NO sewer toilet. The city requires that you have a sewer toilet. You're allowed to have a compost toilet, but you must have a sewer toilet as well. Ah well. Dream house

My dream house would also have a secret sun room and/or a sun room in a tower. And magically stay clean all by itself.

What mullac said. Also, anything in Palm Springs. That's if it has to be a house house.

Otherwise, it'd be the top floor & roof of a small building on main street somewhere in a college town.
