I tried hard to make Sweet Home work for me. It solves the quick and dirty use case but I really wanted something where I could measure out every dimension in the house with a laser measurer, describe the shape and the relationships between the objects and let the computer do the rest. In a program like Sweet Home, and every other floor plan program out there if you make one change (like updating the measurement of the wall thickness you have to manually and carefully move everything else around.
I ended up throwing together something quick and dirty with Org Mode tables and Metapost: https://github.com/guidoism/wildwood/blob/main/house.org
It works pretty well and the output is pretty.
