What are the 2 metric construction modules?
1) hard changes
2) soft changes
What are hard changes?
Establishment of NEW STANDARDS
Such as changing to a metric building standard (from an imperial standard)
______________________ are used for greater precision and ease of calculations (based on a 100mm module)
Metric construction standards
Example of a hard change
1200mm x 2400mm (metric) rather than 4’ x 8’ (imperial)
Not the same size
What are soft changes
Involve the use of existing physical sizes now specified / expressed in metric measurements
______________ do not change the physical size of building material
Soft changes
Example of a soft change
“2x4” changes to “50mm thick and 100mm wide’
This is the same physical size
Measuring Floor Area
Several areas of a house are not included as finished areas to be included in square footage, what are some of these areas?

Example of Measuring Floor area
A finished loft connected by a stairway
