Subdivision Costings

So.. How much does it actually cost to subdivide a property into 2 or 3 lots?

We have done some research across the internet to see what information is available to Western Australians regarding the costs to subdivide a property.

So far all we have found are catchy Google headings & slogans to draw you to that company’s website.

When you arrive at the website you find nothing relevant to help you understand what the actual costs to subdivide your land are and obviously this can be very frustrating!

Typical Project Subdivision Costing

While every subdivision has a different cost attached to it we have found that the costs to subdivide will generally fall within the cost breakdowns in the below drop down menu options.

These 3 options are not always the case but we are confident they will be relevant for most subdivisions.

Cost Breakdown 1 Battle Axe Block - (Keep House)

This will be a straight forward subdivision with minimum site works. The existing house will remain and there are no modifications to the building or renovations required. You will do the absolute minimum to get the lots ready for sale.

Approximate cost here will typically be $30,000.

This $30k should cover you for everything including your government fees, land surveyor fees, plumbing / electrical / settlement and service headworks fees.

Adding things like retaining walls & fences or doing a basic site clean for a new rear lot can push the costs up closer to $35k-$37k depending on who you engage and how much they charge.

Cost Breakdown 2 Battle Axe Block - (Remove House)

This will be a straight-forward subdivision with minimum site works. You will add all of the above-mentioned items in “Cost Breakdown 1” but this time include demolition of the existing house and maybe some outbuildings or sheds to be removed.

Approximate Cost typically will be $50,000 – $55,000 depending on demolition costs!

Obviously here the only difference will be the added costs of demolishing the buildings on site which typically amount to the greatest cost on a small 2 lot subdivision project.

We see prices for Demo of buildings varying between $17k and $25k on average so it is vital you shop around for the right Demo company to keep project costs down.

Cost Breakdown 3 Side By Side Green Title - Sewer Extension (Remove House)

This will be a straight-forward subdivision with minimum site works. You will add all the mentioned items in above “Cost Breakdown’s 1 & 2″ including the demolition of the existing house and maybe some outbuildings or sheds to be removed.

The next cost that may potentially increase your spending here would be if the sewer was not located in the right place to service both new street frontage lots. In this event you may have to do a sewer extension which can work out to be very expensive.

All costs included on this would work out at being at worst $1500 per linear meter. If we imagine you need to extend your sewer by 10m across a lot well then, we simply add 10m of sewer (x) $1500 = $15,000 to your other costings which will get you in the ball park.

This process can be very difficult and needs to be managed by professional hydraulic engineers and surveyors in conjunction with plumbers and Water Corporation.

Approximate cost typically will be $50,000 – $55,000 with demolition.

Basic Sewer Extension over 10m = $15,000

Total Costs (indicative) $70,000
