Custom Home Builder in Belrose: Building Beside Garigal
Your back fence is a national park. The planning rules know it.
Plenty of Belrose lots run straight into Garigal National Park. Sandstone, angophoras, birdsong at 5am. That's the draw. It also means the native vegetation on your block may carry legal protection, and a custom home design has to account for it from the very first sketch.
Short answer
Is a custom home possible next to Garigal National Park in Belrose?
Yes, but clearing native vegetation can trigger the Biodiversity Offsets Scheme under the Biodiversity Conservation Act 2016, so the footprint should be designed around the bush from day one. Bushfire protection zones, plus stormwater and sediment control at the park edge, also shape approval. Belrose custom homes start around $2,530 to $3,050 per m² mid-spec, on Rawlinsons with a 1.15 loading.

When native vegetation triggers extra assessment
Clearing native vegetation for a house, driveway or asset protection zone can bring the NSW Biodiversity Offsets Scheme into play. Two main triggers. First, if any part of the clearing is on land shown on the state's Biodiversity Values Map. Second, if the total area cleared goes over a threshold linked to the lot's minimum size. On typical residential lots under one hectare, that threshold is 0.25 hectares.
Cross either line and you'll need a Biodiversity Development Assessment Report from an accredited assessor, and possibly offset credits. Real money. Months.
Even under the thresholds, council still assesses impacts on threatened species. Around Belrose that includes remnants of Duffys Forest, an endangered ecological community found on the sandstone plateau.
- Check the Biodiversity Values Map for your lot
- Measure proposed clearing, including the asset protection zone
- Ecologist's input where threatened species may be present
- Design the footprint to stay under the triggers where possible
The cheapest biodiversity report is the one your design never needed.
Designing the footprint around the bush
The trick is doing the ecology early, before the house shape is fixed. An ecologist walks the site and maps what's there. Then we fit the house, driveway and outdoor areas into the parts already cleared or degraded, and keep the good bushland intact.
It often produces a better house, honestly. A courtyard plan wrapped around a big angophora. A deck that steps over sandstone instead of blasting it away. Rooms looking into the canopy.

Pass me the address and I'll pull up the vegetation and bushfire mapping. Then we talk through the ecology steps, and how the house could sit on the land without triggering the costly assessments.

Water leaving a bushland-edge lot can't just be piped to the back fence. Why not? Concentrated flow scours gullies, spreads weeds and dumps sediment into the park, and Northern Beaches Council expects stormwater managed on site, often with detention and a dispersal system that releases water gently over a wide area.
During construction, sediment fencing on the downhill side is non-negotiable, and so is keeping spoil, concrete washout and rubbish out of the bush.
Belrose custom homes start around $2,530–$3,050/m² at mid-spec, from Rawlinsons for Sydney with the local 1.15 loading. Sandstone excavation, bushfire construction and any ecology work are priced separately once the site is known.

Custom homes on Belrose bushland lots
What is the Biodiversity Offsets Scheme?
A NSW scheme that applies when clearing native vegetation exceeds set thresholds or affects mapped high-value land. It requires an assessment report and possibly offset credits.
Does the bushfire protection zone count as clearing?
Yes. Vegetation removed or thinned for an asset protection zone is generally included in the clearing area.
Will council let me clear trees for the new house?
Often, with approval, but significant or native trees are protected. The design should retain as many as practical.
Who approves new homes in Belrose?
Northern Beaches Council, postcode 2085. DAs usually take 12 to 16 weeks, longer with bushfire or ecology referrals.
