Is My Site Large Enough To Subdivide?

Updated: May 23, 2018

The appeal of subdividing a block is strong: if you have a large enough block, why not sell off some of your unused ‘backyard’ for a development?

Theoretically, it’s a winning idea and sounds quite simple. The reality of making this happen is often slightly more complicated and concerns more than just sheer availability of space, with many factors coming into play.

Essentially, it’s not easy to tell whether your site is suitable for development, as every site is different and comes with its own set of benefits and constraints.

There’s no hard and fast rule as to how much space is needed to subdivide, as the particulars vary from council to council. To play it safe, however, obviously consider properties that are larger rather than smaller.

In addition to size factor, it’s important to consider many aspects like:

Council Approval

Before you can subdivide, your allotment needs to conform to the local councils’ minimum lot size requirements. Town Planning requirements apply, your lot will be subject to a certain width and overall size, also the Zoning of your allotment sets certain rules you must abide by. All of this information is available on your local councils’ Town Planning Scheme. The subdivision is a separate application to the building application, all of which has to go through Town Planning. I would recommend that Council be your first contact point before you consider subdivision.


Are there any easements on the property? If so, where are they located? It is important to be aware of this as placement of easements could restrict what you’re planning to build. For instance, some easements go across the middle of the site, potentially blocking where you would otherwise intend to be build.


There are a number of costs involved with a subdivision. These can include but are not limited to :- Government and State Statutory levies, connection of utilities will charges fees and levies also.


An often-overlooked issue when considering subdivision is vegetation overlays, often protecting indigenous trees. You may not be able to remove certain vegetation which could impact on your building envelope.

Surrounding Areas

Would your planned subdivision work in with your surrounding environs? A good question to consider is, ‘how does this work in relation to what’s already there?’ Considering all possible objections can save time and hassle down the track.

Position Of Proposed Subdivision

Would the intended subdivision be a duplex or a ‘front and rear’ battle axe development? There are varying schools of thought on which suits best for your block. At Binder Peart Design, we will work with you to advise on the options available.


Is there enough space to build a driveway? This important factor comes into play when thinking about subdivision and the specific requirements of space needed will fluctuate from council to council. Also again the issue of natural vegetation: will this affect native trees and the like?


Your lot may have a restriction on the title which will not allow development to take place.

Sloping Sites

Sloping sites are much more difficult to subdivide, if you have a flat site, overall the benefits are greater, more useable space, cheaper to build on a flat site and not as many constraints.

Other Factors

The reality is that every site has different constraints and an on-site assessment will help shed light on what the possibilities might be. You could be fortunate to have no real restrictions on the site or there could be some major issues which, if identified early, give you the power of choice while you’re still in the planning process.
