Adjustable Wall Height, Sometimes when I’m building a house, I want to make the ceiling look higher, but I can’t raise the walls, so I have to use walls from the second floor. However, when I look at it again, it makes the house look too tall, even though I only wanted to build one story. Or I place basic shapes on top of those walls, but that would make the roof look off and odd. Therefore, I think a house with adjustable walls is useful for people who want to make the ceiling higher for a large house or lower for those building a home for toddlers, or simply for a small house.
