Buying in Grange | the 1946 rule that catches renovators out

Every few months we talk a client out of a house in Grange. Not because the house is bad, but because the plan they have for it is not legally available.

Grange is one of Brisbane's most concentrated pockets of pre war housing. That is exactly why people love it, and it is also the thing that most often derails a buyer who has done their sums on a knock down and rebuild.

What the character overlay actually does

Houses in Brisbane built in or before 1946 commonly sit under the traditional building character overlay. In practical terms it controls demolition. You generally cannot remove the house and start again, and you cannot substantially alter the street facing form.

What you can usually do is raise it, build in underneath, and extend to the rear. Done properly that produces a very good family home, and it is the reason so many Grange houses have a period front and a modern back.

What it means for you as a buyer is that the price you pay has to reflect the house you are allowed to build, not the one you imagined. Check the overlay for the specific address on the council's planning tools before you offer, not after.

Where Grange sits

Grange is around five kilometres north of the city. It has no station of its own, but Wilston and Windsor are close, and the run into town by car or bus is short. Kedron Brook forms the northern edge of the area, which brings the bikeway and the parkland, and also brings a flood question that varies street by street.

Do not generalise about flooding here. Pull the Brisbane City Council flood report for the address you are actually buying. Overland flow is a separate matter again and does not always appear where people expect it.

What we check in Grange specifically

  • The overlay status of the house, and whether previous works were approved.
  • Slope and access. Many blocks fall away, and some have no realistic vehicle access to the rear.
  • Underfloor height. Whether a house can be legally raised and built under is not a given, and it decides the whole renovation plan.
  • Stumps, wiring, roof and drainage on original homes. These are known costs, but they should be known before the offer, not after.
  • Proximity to Kedron Brook and the low points along it.
  • The quality of the renovation already done. A cosmetic reno over an unaddressed structural problem is the most expensive house on the street.

The character is the asset

It is worth saying plainly. The overlay is not an obstacle to be resented. It is the reason Grange looks the way it does and holds the sort of buyer it holds.

Suburbs where anything can be built become suburbs where anything is built. Grange is protected from that, and the streetscape is a large part of what people are paying for. Buyers who understand this early stop looking for a way around the rules and start looking for the house that works within them, which is usually a better outcome anyway.

Schooling

This one confuses people, so it is worth being clear about. The state primary school in Grange is Wilston State School. Despite the name, it sits on Primrose Street in Grange, not in Wilston. Buyers regularly assume from the name that they need to be in the neighbouring suburb, and go looking in the wrong streets.

As with anywhere in Brisbane, catchment is decided by the address rather than the suburb, and boundaries change. If the schooling is a main reason you are buying here, check the current map for the exact property before you commit rather than relying on the suburb name or on what an agent tells you at an open home.

Getting it right

The homes that work in Grange are the ones where the renovation plan and the planning rules agree with each other. Working that out takes a look at the overlay, the block, the house and the council record, and it takes doing it before you are contractually committed.

We act for buyers only, we never list or sell, and we take nothing from agents or developers. We are in these streets weekly and we will tell you plainly when a house does not stack up.

If you are considering Grange, get in touch and we can talk it through.
