Block Subdivision

Perth is currently going through an Urban Infill program (Subdivision), which is focusing on sub diving larger block sizes to increase the population density in the Metropolitan area and also redeveloping areas to increase the usability of the land. By 2050 Perth and the Peel region will have a population of 3.5 million people, and require an extra 800,000 thousand homes, from that, an expected 400,000 homes will be constructed as part of Perth’s urban infill program.

Some of the first urban infill areas were located close to the Perth CBD and focused on sub diving larger blocks. Areas such as Bayswater, Innaloo, Morley, Maylands, Ascot, Cloverdale, Belmont, Inglewood, Bedford and Victoria Park.  As local governments start passing zoning changes throughout Metropolitan Perth, block subdivisions is becoming extremely popular, with people purchasing larger blocks in order to sub divide and develop.

Land Subdivision Plumbing Works:

  • General Plumbing works: Relocating services, water, gas etc.
  • Drainage: Relocating storm water systems, installing them and additional soak wells. Depending on the soil conditions and local government.
  • Sewerage: Relocating, re-running, additional sewer points and sometimes installation of new connections.
  • Gas: Installation of new gas services to properties.
  • Water: Installation of new water services to new properties, or relocating services.

Some pitfalls that owner / developers may want to consider in setting up a budget for their subdivision project:

  • Older homes will require a functioning stormwater system – and be brought up to code in regards to stormwater and sewerage.
  • New fencing – New fences will often be required to devide each property – depending on the type of development you are undertaking
  • Sewer will often have to be re run – This can be a simple process or become more complex depending on the depth, location, etc.
  • Installation of Stormwater pits, pipes and drainage – Some blocks require a stormwater system be installed before sale. Ask your local government for details on the requirements before proceeding.

The R-Zoning code which your land falls under will dictate how your land can be subdivided, either as a green title block (Stand alone, individual blocks with no strata title or common / shared land) or split up under a strata / common land title, usually sharing the same driveway, main storm water system and common trenching for services. A brief snapshot of the R-zoning codes are listed and described below;

R10: Average site area of 1000m2 per dwelling and a minimum of 875m2
R12.5: Average site area of 800m2 per dwelling and a minimum of 700m2
