A minimum of 20 percent of the site will be needed to be planted or grassed—this will also encourage existing trees to be protected—and the outdoor spaces can be grouped so that units can group their outdoor spaces to create a shared, larger outdoor space. There's a slight change to front setbacks: they're reduced so as to leave more land at the back, where most of the shared space or individual space will be, and the height to boundary is recommended to be changed. At four metres at the boundary, with a 60-degree recession plane, it, effectively, means that for every metre in, you go 2 metres up. That results in a net loss of intensification of only 4 percent, but it has a better outcome in respect of shading or sun.
