Site coverage refers to the percentage of building coverage over the site; usually a maximum site coverage of 60% applies
Elements to be included and excluded
Basically, site coverage includes anything with a roof! Even an upper level cantilevered over the ground is included.
1 | Front porch (roofed) |
2 | Rear patio (roofed) |
3 | Dwelling |
4 | Open deck with concrete under |
5 | Gazebo (roofed) |
6 | Pool |
7 | Paved area |
8 | Cubby |
9 | Garden shed |
10 | Eave overhang |
11 | Gravel driveway |
12 | Open deck with natural ground under |
Shaded green | Trees/shrubs/lawn |
Let’s say the total site area is 600m2 and the highlighted elements have the following areas:
Front porch (roofed) | 4.00m2 |
Rear patio (roofed) | 8.50m2 |
Dwelling | 200.00m2 |
Gazebo (roofed) | 3.00m2 |
Cubby | 8.50m2 |
Garden shed | 7.00m2 |
Total | 231.00 |
Site coverage =( (Total Building Area)/(Site Area) ) x 100
=( 231.00/600.00 ) x 100
=38.5%, less than 60%
