This kind of house is called Colonial house because they were built by the colonist that came to America in the 1700th century.
At the time timber were vast in supply and they built the houses as fast as they could to provide shelter for the colonies. The design was thought as sturdy, big and could host as many people as it could without wasting space.
I got this diorama house model from a Korean interior design website. It was displayed on their monthly wallpaper calendar issue and a free 3D paper model were included. There were many more and I’ll be posting them soon
The only downside is they came in white model which you’ll have to color it yourself.
