My first intro to glitter houses was in the 40’s when I was a kid living in Hamilton Ontario.
I have made a 1/4” glitter house using some of the directions on the Glitter house web site. I also made some tinier ones. The cardboard can warp but to help prevent it be sure to paint or paper both sides of the card. Here are a couple pictures of ones I have made. Since you have limited space you might like to make some like I show in the third picture or the tiny house in the bigger one.

I furnished it instead of just a hole in the back for a light. Notice the tiny glitter house in the bedroom
like the big one. Had a bit of warping on one side but it can add to the charm of a hand made piece.
A row of tiny glitter houses that could go on a 1” scale mantle. These are made from solid wood pieces.
The fences are card.
