Confused about open areas

Hi everyone,

so open area space according to the R-Codes should be minimum 45% on an R40 block.

We built and it somehow doesn’t have 45% open area if it includes the garage see images below.

Can someone please explain?

 

There's a few things at play here

- most councils will allow 3% extra coverage (so down to 42% open space)
- Areas which are open on 2 sides aren't included in site coverage so it's likely the portico (or some part of it) and the alfresco are not included.
- common property (ie driveway) is also used in calculations

C4 Open space provided in accordance with Table 1 (refer Figure Series 6).
The site of the grouped dwelling, for the purpose of calculating the open space requirement, shall include the area allocated for the exclusive use of that dwelling and the proportionate share of any associated common property. ​

 

Thanks Westminster, I don't know why I missed this, honestly I thought that common property was excluded as open sapce if it was a driveway, I must have gotten this mixed up with something else.
