Home Builder began as an app for drawing homes. You can scan a room with your phone, trace a floor plan or draw from nothing, then look around it in 3D.
A plan on a screen stays on the screen, so we taught the app to make the house as well: first the files for a 3D printer, then sheets of paper to cut, fold and glue.
This shop is the same idea with the drawing done for you. Each house here is a plan made in Home Builder. The pictures, the floor plan, the 3D view, the print file and the paper parts all come from that one plan, so they all show the same house.
