Battle-axe blocks raise a fair question, because the shape of the land is unusual. The short answer is yes, you can usually build a granny flat on a battle-axe block, and in some ways these blocks are well suited to it. The thing that needs the most thought is access, and that is exactly where a transportable home has an edge.
If you own one of these handle-and-flag shaped lots and you are weighing up a second dwelling, here is what to know about delivery, setbacks and approval, and why factory-built often makes the most sense.
A battle-axe block sits behind another property, connected to the street by a long, narrow strip of land. That strip is the handle, or the access leg, and the main usable part of the block sits at the back like the head of an axe. They are common across Sydney where larger original lots were subdivided to fit a second home behind the first.
The upside is privacy and space. The main living area sits away from the street, the block is often generous, and there is usually room to place a granny flat without crowding the existing house.
The handle is the catch. It is usually only a few metres wide, sometimes shared as a right of way, and a conventional site build means trucks, trades and materials coming and going down that strip for months. On a narrow handle, that is awkward at best and a real headache at worst.
This is the heart of why a transportable home suits a battle-axe block so well. The home is built in our factory, then delivered and installed in about 2 days rather than occupying the access leg for the length of a full build. There is one careful delivery rather than months of traffic up and down the handle.
Before anything is locked in, we look at the access carefully. The width of the handle, any tight turns, gates, overhanging trees, power lines and the surface all matter for getting a transportable module in. On some blocks a craned lift is used to place the home over an obstacle. The point is that this gets checked up front, so there are no nasty surprises on delivery day. You can see how we plan all of this on our our process page.
Like any block, a battle-axe lot has setback rules that set how close the granny flat can sit to the boundaries. The good news is these blocks often have the space to meet them comfortably, because the usable head of the block is generous. Your certifier confirms the exact setbacks for your site.
Placement also affects privacy and light. With the main living area set back from the street, you usually have freedom to position the granny flat for north-facing living and a sensible separation from the existing house.
Approval works the same way it does on a standard block. Most blocks of 450 square metres or more in a residential zone can be approved through the Complying Development Certificate (CDC) pathway, signed off by a private certifier in about 10 to 20 business days. Many battle-axe blocks clear that size easily because the original lot was large enough to subdivide.
If your block has an easement, a shared access arrangement or another quirk, it may need a Development Application with council instead. It is worth confirming early. There is more in our guide to how granny flat approval works in NSW.
With the room most battle-axe blocks offer at the rear, you often have your pick of designs. A full 60 square metre two-bedroom like the Banksia 60 with its separate kitchen and deck works well where there is space, while a more compact home suits a tighter rear yard. Browse the full range of designs to find one that fits your block and your access.
In most cases yes, with planning. We check the width, turns, gates, trees and power lines before delivery, and a craned lift can place the home over obstacles where needed. The access is assessed up front.
Not automatically. Many meet the CDC criteria because they are large enough, but a shared access arrangement or easement can push the job into a DA. Confirm your block's specifics with a certifier.
Because the home is installed in about 2 days rather than tying up the narrow access leg for months of trades and deliveries. Far less disruption on a block where access is the main constraint.
The best next step is to have us look at your access and your block size so we can tell you exactly what fits. Visit our granny flats and studios page to see what is possible, then contact us for a fixed quote based on your site. We have built and delivered transportable homes onto all sorts of tricky blocks across NSW for over 30 years.
