Maybe it would be nice that TLG makes a some sort of an abandoned modular building like a haunted house that would fit with the existing modular building.
Or they could quit the modular building series with a different modular series, like suburban houses with a little garden in the front and spaces between the buildings.
I am just thinking about a new idea for the modular series, because I have some doubts about TLG releasing these modular buildings in a way they do it currently. I think they can't do it for decades, because it becomes harder to make new next level outstanding buildings as they have released more modular buildings over time.
