This makes me a bit sad.

But if you were allowed to/worked out a deal to paint those side walls, that could be a really cool looking space.

I'm guessing not especially quiet though.
- Depending on its orientation, it’s probably pretty dark inside too.

Time to buy the balloons.

Reminds me of the Edith Macefield house, in Ballard (Seattle, WA).

.

If you're ever in Ballard, I highly recommend the excellent cocktail bar Hazelwood, which pays tribute to her with a namesake cocktail (the Edith Macefield).

I think if the house was first then that’d be sad, yes. But if someone bought the lot and managed to get a house in there legally (or just got away with it) then that’s pretty rad. Like a brilliantly yellow dandelion forcing itself through a crack in an otherwise seamless, lifeless and bland sidewalk.

I think the house being there first is the more likely scenario. I like your optimism though!
- I don't know if that is the most likely scenario, I think those building on ether side would have side windows if that was the case. I think you only build walls like this if you are right up to the next building.

It’s like a sad Wes Anderson film

Imagine those buildings are your two favorite things! Maybe a bakery and a library!

Or a brothel and opiod den!
- And imagine it was the seventies and serving hatches were still fashionable...

I kinda love it. Imagine kids playing ball games out there so fun.

Do you happen to have the original ad? I am kinda interested in how this is set up and where.

This is what we call a shoebox house in Montreal. There are quite a few in my neighbourhood. See more in this article. Mind you, these are pictures of the pretty ones, they are not all as cute, but not many are as far recessed from the street either.
The earliest source I can find is a Tumblr post from Dec 2015, but I could not locate the address. You may be able to get in touch with that account, though it's a long shot given the age of the post.
- Nice detective skills!
Sorry, most of these are ancient. You could try reverse image search but I don’t suspect you won’t find much more info.

  No joy but I did find this remarkably similarly sited building. It may be quite common. Apparently part of a class of buildings the Chinese call nail houses.
- Ah too bad. I kinda want to find more like it. You could put up a facade on the street and have like a secret home. Might be a good option in some decaying citys.

ngl i would love living there, both as a child and adult. there's still plenty of space, and the walls could facilitate a lot of new games. also, as someone else said, if you could paint them it would be even better

I wonder if those walls protect the house from external sound, or do they amplify it.

I hope it's oriented right, otherwise you're living in eternal shade

Wonder what the back yard looks like?

Car park for the buildings next to it?
- Sweet, free off road parking with built-in security cams? Sign me up!

Here's another good one (open street view):

Was for sale for 300k cad not that long ago if I recall correctly.

Those are what's called shoebox houses. We find a lot of them in Montréal, Québec.

Here are a few more.

I would love this.

Some people would pay good money for a privacy fence like that.

I don't know, shelter and a sizable yard aren't so bad. but it could do with some decorating

It’s not the house itself that makes me sad - it’s kinda cute and I dream of a private garden. But I suspect this house was here before the (presumably) commercial buildings either side and that makes me sad. Like Chinese nail houses.

It's like living in a narrow valley.

This is just the house from Big City Greens

This looks about average for a new build council home...
