Two-storey modular buildings can help increase the amount of usable space when the available construction area is limited.

The building shown in the image uses a regular arrangement of modular rooms with an external corridor, staircase and protective railings. Individual doors and windows provide direct access to each room, while the projecting roof can offer basic protection for the circulation area.

This type of layout may be considered for workforce accommodation, project offices or other temporary site facilities. Room dimensions, escape routes, staircase design, fire protection, sanitary facilities and structural requirements must be evaluated for the specific project.

A clear circulation system and consistent room arrangement can also make daily site management more organized.
