4. Volumetric

5. Can you think of a type of project where it would be crucial to use volumetric construction?

6. Would you live here?!

7. How long did it take to construct Container City 1 and how long it would have taken if constructed the traditional way? Container City 1

8. What could be the practical considerations for volumetric construction?

9. Volumetric construction: bathroom and kitchen pods Bathroom in a box

11. Practical considerations for volumetric construction (Pods)

12. Summary of Pod cost data
