Buildr™ — see exactly how a home sits on the block.
The Buildr house siting engine drops a home footprint onto a real cadastral lot and reads a plain pass/fail verdict — auto-anchored against the front, rear and side setbacks, with every breach drawn on the actual room walls, not a bounding box.
Site a real home on a real block — right now.
Enter an Australian address and the engine resolves it against G-NAF, pulls the actual cadastral lot and planning controls, anchors a real production home design inside the setbacks and scores how the home would live on that block. Free to try — no sign-up, nothing mocked.
The design being sited
Loading showcase design…
This is a real design from the catalogue. Its room dimensions and footprint were measured from the uploaded floor plan — the geometry the engine sites is the real geometry of the home.
The plan mirrors automatically so the garage lands on the driveway side you pick.
Site a build honestly, before you draw a line.
Buildr answers the first question of any project — does this home fit this block — from a single address.
Auto-anchored to the setbacks
The footprint snaps against the front, rear and side setbacks resolved for the site, so you are testing the design against the envelope that actually governs the lot — not a guess.
Pass/fail on the room walls
Boundary segments show green where the legal setback is met and red where the building crosses the envelope, clipped to the actual room walls rather than an approximate rectangle.
Measured from the floor plan
Room dimensions, the habitable footprint and overall widths are pulled from an uploaded floor plan, so the geometry the engine sites is the real geometry of the home.
Test fit and orientation
Overlay a candidate design on the parcel to check fit, orientation and driveway side against the real boundary before committing to a plan.
