Background
Biaolan Diao applied to Ku-ring-gai Council for consent to reconstruct the front of an existing dwelling and build substantial rear additions at 42 Chelmsford Avenue, Lindfield. The proposal also included a basement, swimming pool and conversion of an existing garage into a studio. After the application was deemed refused, Diao appealed under s 8.7 of the Environmental Planning and Assessment Act 1979 (NSW); the Council subsequently refused the application on 23 April 2026.
At a court-directed conciliation conference on 21 and 22 July 2026, the parties agreed on an amended proposal and consent conditions. The amendments included a narrower driveway, improved landscaping, a larger side setback, a more articulated rear addition with a more sympathetic roof form, and changes to windows, the pergola, fencing and finishes.
The Court’s Holding
The Court upheld the appeal and granted development consent for the amended application, subject to the conditions in Annexure A. Commissioner Gray was satisfied under s 34(3) of the Land and Environment Court Act 1979 (NSW) that the agreed decision was one the Court could properly make and that no jurisdictional constraint prevented the consent orders.
The Commissioner found the relevant statutory preconditions satisfied, including permissibility in the R2 zone, compliance with height and floor-space-ratio standards, and consideration of heritage, earthworks, stormwater, contamination, Sydney Harbour Catchment, BASIX and public-submission requirements. In particular, the amended development would not adversely affect the significance of the Clanville Heritage Conservation Area. Because the orders implemented a conciliation agreement, the Court expressly made no evaluative judgment on the matters originally disputed or broader assessment of the proposal’s discretionary merits.
Key Takeaways
- A Class 1 development appeal may be resolved through a conciliation agreement if the Court is satisfied that the agreed decision is legally available and all jurisdictional preconditions are met.
- Design amendments addressing driveway width, landscaping, setbacks, roof form and exterior details supported consent for residential works within a heritage conservation area.
- Orders made under s 34(3) do not necessarily represent a judicial determination of the original disputes or a full evaluative assessment of the development’s discretionary merits.
Why It Matters
The decision illustrates the limited but essential supervisory role of the Court when parties settle a development appeal through conciliation. The Court must verify that the agreed outcome falls within its statutory authority, even though it need not decide the contested planning merits.
For heritage-area projects, the case also demonstrates how targeted design revisions and supporting expert and technical material can resolve objections and establish the statutory foundation for an agreed consent.
