Two-storey villa — coordinated escape plates
A two-level residential escape-plan set with a shared drawing scale, aligned stair IDs, and two independently checked routes on each floor.
For the property manager coordinating posted plans across a two-storey residence
One scale, two independently checked sheets
The repeated S1 and S2 IDs register two continuous stairwells. A coordinate drift over 0.1 m becomes a warning, while each level still has to carry its own marker, exits, and routes.
