I was actually preparing information to add make my own thread, but I'll just add it here. This might help give some reference for people talking about it.

In this
video, we get a really good look at Nook’s shop at 4:45.
We can see there are a number of categories of ways to remodel your house. If I were to guess them from the video I would label them (From back right clockwise)
Courtyard
Roof: Can’t tell if this is just color or also style.
Entryway?
Fencing
Overall Style
Door (2)
Mailbox
Here’s another screenshot from the site of the shop.
Different styles
At 4:53 in the same video, they begin showing examples of the various houses.
Classic AC
These photos shows evolution of the classic Animal Crossing home via upgrades. It has a white picket fence, a cobblestone courtyard, white siding with some stone work, a rounded door with a circular hole, a red mailbox and a red roof.
Here’s a futuristic full set. The basic styling of the house is the same, but the fences, courtyard, siding, roof, etc. All have a futuristic and metal look to them.
This one is very kiddie looking. Again, very basically the same style, but with everything fitting the theme.
This one is very pastel and feminine.
On the other end of the spectrum, we have an outdoorsy cabin.
This one is very Japanese. Now, this one is really interesting, because it’s very different in shape than the other examples we’ve just seen, which very basically the same base with relatively miniscule changes. I suspect the overall style changes will give you shape changes like this.
This one is from the official site. Note how both sides houses are a similar size, but one has a plain roof while the other has dormers. Perhaps those are optional?
This one has a hedge as the fence. Kind of reminds me of the ranch set? Also, the courtyard is a pink stone.
Wood paneling in the courtyard, wood fence, along with a sweets-ish looking roof. This one’s kind of all over the place.
A different style of wood fence here. Classic cobblestone courtyard. A diagonal siding.
On the left, we have a house that very much resembles the classic on from the other game. I’d like to classify the house to the left, but I have absolutely no idea what to call it. Tell me if you have some idea.
Town Hall
It was revealed in the October Nintendo Direct that even the town hall can be remodeled. The first picture seems to be the basic model. The second one is brightly colored and onion-domed. I hope a similar style is available for houses.
I’d almost like to start classifying these, but there’s simply so many and I can’t tell what the official names will be.
If you have anything you think I should add or any suggestions for organizations, let me know.
More Screenshots from Japanese Commercials
A pink tile courtyard, pink roof, brick siding, Asian-inspired door, blue door, yellow mailbox.
All I'm going to call this is "The 80's called and they want their house back".
This is the same shape as we saw in the first video I posted on this thread, but with a different roof color.Hopefully, this means you can still edit the less usual shapes in ways.
