Development Applications in North Kellyville, NSW

Development activity in North Kellyville

If you’ve worked construction in the Hills district as long as I have, you’ll know North Kellyville wasn’t always this busy. Ten years ago, you’d drive through and see more bush than blockwork. Now, it’s a different beast. The residential building scene here is humming, and it’s not just the big volume builders churning out project homes. We’re seeing a solid mix of new home construction, home extensions, and first-floor additions, plus a fair bit of knockdown-rebuild work on the older lots. Right now, there’s four development applications lodged with the local council, which tells you the pipeline is still healthy, even with interest rates doing their thing.

The housing stock in North Kellyville is split pretty cleanly. You’ve got the newer estates off Withers Road and around the Kellyville Village side—standard 400 to 500 square metre blocks with single-storey brick veneers from the early 2000s. Then you’ve got the older pockets, closer to the creek lines and the original rural-residential lots, where you’ll find fibro cottages and weatherboard homes from the 70s and 80s on acreage. That’s where the knockdown-rebuild action is. A lot of those blocks are getting subdivided, or the owners are cashing out to upsizers who want a two-storey family home with a pool and a slab for the caravan. The newer estates are where we see the first-floor additions—people bought in when the market was hot, and now they’ve got three kids and need another bedroom and a rumpus room without moving.

Clients here aren’t your typical first-home buyers. North Kellyville is firmly in upsizer territory. You’re dealing with families who’ve been in the area for a decade or more, often moving from Baulkham Hills or Castle Hill. They know what they want: four bedrooms, a study, a butler’s pantry, and a covered outdoor area that doesn’t leak into the neighbour’s yard. They’re not price-sensitive in the same way investors are, but they are time-sensitive. They want the job done before the school year starts, and they’ll push you on the program. Renovators are a smaller slice, but they’re out there—usually the ones who bought a fixer-upper on a big block and are slowly bringing it up to spec. Investors are thin on the ground. The yields here don’t stack up for a standard rental, so most of the work is owner-occupied.

The local council has a reputation that builders should know about before they lodge a DA. They’re not the fastest in Sydney, but they’re not the slowest either. If you’ve got a clean application—standard new home on a compliant lot with no tree issues or flood overlay—you’re looking at around 12 to 16 weeks for a determination. But they’re fussy on landscaping plans and stormwater details. I’ve seen jobs held up for weeks because the site plan didn’t show the rainwater tank connection to the toilet. They also push hard on solar passive design and cross-ventilation, so you need to have your energy rating sorted before you submit. The common conditions are the usual: a construction management plan, a dilapidation report for the neighbours, and a bond for any council infrastructure damage. Nothing a decent draftsman can’t handle, but it’s not a council you can bluff.

The market itself is steady, not crazy. Land prices have softened a bit from the peak, but they’re still high enough that a knockdown-rebuild makes sense if you’ve already got the block. New home construction is running about $2,500 to $3,000 per square metre for a decent spec—mid-range finishes, engineered stone, tiled roof, ducted air. You can go cheaper with a project builder, but most of my clients are after something custom, so they’re budgeting closer to the top end. The extensions are a mixed bag. A single-storey rear addition will run you $4,000 to $5,000 per square metre once you factor in structural changes and council compliance. First-floor additions are more expensive again because you’re dealing with new footings and a steel frame. The
