My Aunt and Uncle’s house in the Catskill mountains, they had it built in the 1950’s. There was an open dining / living room with a brick fireplace open on two sides and a big picture window from ceiling to floor with a view of Mount Overlook. Lots of light and air. Step outside the door and you could run around in the woods.
My family was lower middle class, but I went to school with rich and poor alike, including kids from the Hickel family in Alaska. The lived in what was to my eyes a mansion, with all sorts of cool stuff inside and a basketball court outside. I was always ga-ga when I went over there to shoot hoops.
I did a dream home project for some class in Elementary school. All I remember about it was almost every room had a rather specific purpose (“This is my G.I. Joe room!”), playground slides connected most of the house, and there were multiple elevators.
I always wanted either the Brady Bunch house or the original Parent Trap house. After the last 12 years living in skinny 4/5 story terraced houses in London, I would kill for lateral space!
Your Dream House should come with Dream Domestics. 
Yeah, I wanted either the house from the movie Clue, or Collinwood from Dark Shadows.
Yes! I am in awe at how sophisticated Dopers’ tastes were as children!! The big thing I remember was that in fifth grade, my classmate wrote a short story where one of the characters used a slide that connected to her bedroom window to leave her house, and I thought that was the coolest idea ever and wanted to have one for myself. I suppose I also wanted a secret passageway.
Oh…movie houses. I wanted the house from both the movie The Ghost and Mrs. Muir and the TV show. The house in Mrs. Miniver was also sweet.

I had a page from a magazine of where I wanted to live when I grew up. It was a small room and the bed was a loft accessed by a ladder, and under the loft was the living space. I remember the whole room was red.
And then I DID live in my dream home:
When I grew up my tastes changed and I wanted a one-bedroom apartment, downtown, with a bathtub and a bay window. Long story short, I ended up moving downtown into a house (built in 1867 and converted to apartments) that I wanted to live in since I was 13. I started in #11 but then #10 came available - which was a one-bedroom with a bathtub and a bay window. I lived there for 9 years until it was time to move into my husband’s home. I still miss that place.
I didn’t have a dream home as a child, but a couple years ago I had a literal dream about a house which is probably the largest house I’d feel comfortable in. The middle was a conservatory/gallery with open walkways between the two other, more houselike parts. So basically a house nearly the size and dimensions as a standard 2 story box house but with a naturally-lit gallery inserted into in the middle. Both stories of both “house” halves have parts that are open to the gallery, and each side has enough room for a couple bedrooms and a bath.
I visited The House On The Rock as a kid and immediately thought of it as the ultimate dream house.
I grew up in a log house. Not an old one, though.
For at least a couple of the features, that’s still my dream house, though it’s MUCH bigger than I want. When we bought our house, we both noticed how much the deck reminded us of the house I grew up in. It’s high up and looks out over a wooded ravine.
The house I grew up in is still in the family. Now it’s used year round as a vacation rental.
I just wanted accessories: A hand in a box to bring in the mail (or other jobs), a bedroom/bathroom combo like Matt Helm (the bed tipped up and dropped you on a conveyor belt which ran you through the shower and dressing areas [MH always had girls around, but, YUCK!]), and a Green Hornet garage, where you pulled your car in and clamps held it in place while the platform rolled the car underneath. And an elevator like the Jupiter-2.
Dammit, I forgot to answer the actual question! I’m dumb.
I wanted to live with Willy Wonka SO BAD. I weirdly wanted edible balloons, which now makes me uncomfortable, though I never felt the chocolate river was hygienic at all.
I wanted to live in a 1960s bachelor pad with a tiki motif, sunken conversation pit and a huge tube amp stereo system.
I was charmed by Le Corbusier.
Now I wish I had something like this though doesn t seem to happen!!!
I wanted to live in the Addams Family house from TV. With them in it.
My dream home was one of those big three story homes, with tons of rooms, in on part of town that was built in the late 1800’s, early 1900’s. Gingerbread work all over, narrow back staircases for the servants, and a little room at the top front corner with windows that circled all around it/ I wanted to have my own little lair up there.
I recall when we were shopping for our house here 30+ years ago and the realtor asked what are you looking for in a house. I said a turret. My wife looked at me then agreed. Yes a turret. While there were such houses in the area none were for sale, at least in our price range.
As for specific houses, I always wanted to live in the house where I lived from ages 0 to 6. I don’t recall too much about it but have always been nostalgic for it. It had a room above the garage, but I don’t recall ever being in it. It had a huge backyard that backed up on a small farm and Mom would send me over to get fresh corn. My bedroom was on the third floor and it had a dormer you could walk into and look out the window.
Many years after we moved out and after I was in college or later the owners (at least three later) told me about a small hidden closet off the basement room next to the fireplace. I was heartbroken I’d never found it.
The White House. Or something like it. White with columns.
you might be interested in Marbella, Spain, then. There are pretty a lot of those
