When designing apartments, often it is necessary to understand the relationship between an apartment and its external areas. However, in Revit, only elements of specific categories, such as Doors and Windows, have this functionality built-in via the room calculation point. This tutorial demonstrates how we can use this approach on Curtain Panels to renumber balconies and terraces based on their associated apartment.
Background
Understanding the relationship between an apartment and its external areas is frequently required for compliance testing. For example, section 4E of the NSW Apartment Design Guide requires that minimum areas and depths be achieved for private open areas. These requirements are based on the dwelling type:
| Dwelling type | Minimum area | Minimum depth |
|---|---|---|
| Studio apartments | 4m2 | – |
| 1 bedroom apartments | 8m2 | 2m |
| 2 bedroom apartments | 10m2 | 2m |
| 3+ bedroom apartments | 12m2 | 2.4m |
