A lot of builds have details that extend from their baseplates. This is fine as long as it sticks out over the walkways only. This can cause problems with people who want to build next to you. So please do not let roofs/windows/etc. stick out over empty lots.
ayy i see my houseedit: didnt realize this was a thing and my house is probably deleted now
if your house did this then i only removed the ramps that were sticking out over another lot
