Subdivide & conquer, with Developments by Dale Alcock

Whether you’re a mum and dad investor or seasoned developer, subdividing land has the potential to land you significant profits through smart development.

Put simply, the process involves creating two or more blocks of land from a single ‘master block’. You can even merge multiple lots with the ultimate aim of subdividing the new ‘mega block’.

Intrinsically linked to this process are the R-Codes that apply to the lot you wish to subdivide. R-Codes are a part of a state planning policy that provides a comprehensive set of controls for residential development in Western Australia. They influence everything from the approval process to design elements and, most importantly, the number of dwellings you can build on a certain block.

From a subdividing perspective, understanding R-Codes is essential to unlocking the full potential of the property in question. First you need to find out the zoning of your lot. Then by taking into account the overall size of the lot, you can calculate your subdivision possibilities.

From here, you can design a smart development perfectly placed to gain council approval.

House Behind House Development - Doubleview 2


House Behind House Subdivision (Perth)

Triplex & Duplex Development (Perth)
Purchase a vacant block or demolish an existing home to subdivide and build two or three properties.

Multi Unit Developments (Perth)

 Minimum site areas for exclusive use
✓ Setbacks
✓ Averaging and heights
✓ Overlooking neighbour’s amenity
✓ Streetscape
✓ Open space
