A worked example: 87-105 Racecourse Road, North Melbourne, Victoria

Example, made on 3 November 2026. An example, made by running the app on this site. It isn't a planning decision, a planning application or professional advice, and the site's owners have nothing to do with it. The units are generated, not designed.

The same data as JSON: /example.json. You can make it yourself: open the app and choose Try an example. It may have moved on since this date.

The site

A real, largely vacant lot, City of Melbourne property 616843. The City's Development Activity Monitor lists approvals for 12 storeys of apartments here (read 3 November 2026). The design below is what the app's Fill made, not an approved design.

• Area: 6,487 m²
• Zone: PRZ1
• Overlays: BFO1, CLPO, DCPO2, DCPO4, DDO26, EAO, LSIO3, PO16
• Development type chosen: RES_HIGH (high density residential)
• Boundary: City of Melbourne Property Boundaries (CC BY)

The design

Made by Fill, with the site's development type and no other choices. It placed 1 of the 3 buildings the type's target asked for, with 72 homes. North is up in the plan.

High-Rise Apartments (9+ storeys): 12 storeys

• Footprint 833 m² over 12 storeys. The units take 5,995 m²; the rest is core, corridor and services.
• 6 units a floor, 72 homes, double-loaded corridor, a lift and two stairs
• 67% of homes cross ventilated

The mix it aimed for: 4,140 homes in 60 completed developments within 1.5 km (City of Melbourne Development Activity Monitor)

• The plate is 28 m deep: units are 11 m deep, with corridor and services between.
• Generated layout: an indication of what fits, not a design. The core follows the NCC's exit rules only as an indication (not a building-code check).

On the ground: 1 path, 1 driveway, 3 parks, 12 trees, 7 fences.

The Check

26 findings: 0 break a rule, 0 need a variation, 7 to check on site, 6 weren't checked, and 13 found no problem. No problems among what was measured doesn't mean the design complies: the findings that weren't checked, including this zone's own height and setback controls, are still open.

An indicative pre-check, not a planning decision. Overlay controls other than DDO building heights aren't checked yet, and Clauses 57/58 only where the design or an imported model's rooms show them. Rules as of: VPP to VC317 (20 Oct 2026); Building Regulations 2018 Part 5.

Permits likely needed

Approval routes

• Planning permit (regular) (available): Needed for DDO26, LSIO3; notice to neighbours and review rights unless an exemption applies.
