Local rules
Balgownie: brick homes around a village centre
Brick, tile and some weatherboard
Chapter D1 of council's Development Control Plan describes Balgownie's typical home as a detached brick house with a pitched tile roof. It also notes that timber suits the street close to the shops, where weatherboard houses already stand, and denser housing on the main road. So choosing materials for an addition comes down to your own street, not a single suburb rule.
A real mix of housing
In 2021, 5,722 people were counted in Balgownie, across 2,290 private homes. Of occupied homes, 71.8% were detached houses and 26.1% were attached semis, terraces or townhouses. That attached share is higher than many nearby suburbs, but that figure cannot say whether a second dwelling will fit on your block.
Centre and foothills
The village centre sits within Foothills Road, Kembla Street, Napier Street and Balgownie Road. Businesses there sit under different controls from nearby homes. Up toward the foothills the land rises, sometimes steeply, so order a levels survey showing the true usable area before design begins.
Typical work
Common projects and how they get approved
What owners build here
Balgownie owners tend to adapt what they already have, rather than knock down and start again. Typical projects:
- Second storeys on brick houses, with careful roof junctions in streets that share a uniform pitched roof line.
- Rear extensions and internal reworks to older detached homes, matching existing brickwork where it shows.
- Dual occupancies and townhouse style proposals, only where the zoning, frontage and area allow.
- Patio roofs, pools and garages fitted around the leftover yard and driveway.
- Granny flats behind existing homes on lots with enough level, usable space and side access for construction.
How approval usually works
A CDC (complying development certificate, the state code shortcut) can work for a Balgownie second storey or pool when both block and plans comply with the code. Character guidance in the DCP supports a design response for a development application (DA), but it cannot make a project code compliant. Before lodging, check zoning, frontage and lot area if you want an extra dwelling. Know the difference between a granny flat linked to your home and two separate dwellings, as they are defined differently. On a sloping site, get levels surveyed early. Shop top flats over business premises are not Class 1 or Class 10 work, so they need another class of certifier. CertifiBuild reviews your lot's controls and slope before you commit, and keeps the paperwork moving once building starts.

Local questions
Questions we hear about this suburb.
No two lots in Balgownie are the same. Give us your address and we will check every map that affects it.
See the council pageIf townhouses went up nearby, can my Balgownie block be redeveloped too?
Not on that basis. Townhouses down the street only prove that attached housing exists in Balgownie, where attached homes were roughly one in four dwellings at the 2021 Census. Whether your block can take a second dwelling turns on its own zoning, frontage, lot area and the development standards. A granny flat linked to your home is also defined differently from two separate dwellings, so be clear which you want. On the foothill side, a levels survey shows how much usable ground there really is. Get the block assessed before paying a designer for a layout.
Must a Balgownie addition be built in brick?
Not always. Wollongong council’s design guidance (its development control plan, or DCP) treats the detached brick house with a pitched tile roof as Balgownie’s typical form, yet it also accepts timber close to the shops, where weatherboard houses already stand. So the right material depends on your own street and not a blanket rule for Balgownie. Look at the houses immediately around you, then check any consent conditions or heritage requirements on the lot. Remember the character guidance supports a development application (DA) design response, but it cannot make a project comply with a State code.
Could my brick house be given a second storey?
Possibly. Many Balgownie streets share a consistent pitched roof line, so the join between the new roof and the old one deserves real care. Check the current structure first, including whether the brick walls and footings can take the load, then look at setbacks and neighbours’ windows. A complying development certificate (CDC) may suit if your lot and design tick every box in the State code. If not, the upper floor goes through a development application (DA), and council then weighs its guidance on brick and tile homes.
