Reality Capture on the Gold Coast: Knock-Down Rebuilds, Canal Estates and Zero-Lot Boundaries

On the Gold Coast, many of the most valuable building sites already have a house on them. Older homes on the canal estates are being knocked down and replaced with something much bigger, on lots where the new walls go up close to the boundary and the water sits just past the pool. Inland and up in the towers, owners are gutting apartments and rebuilding them to a high finish.

All three jobs have the same weak point: what was there before work started. This spotlight covers knock-down rebuilds on canal blocks, zero-lot boundaries and high-rise fit-outs, and how a dated 3D record protects the owner, the builder and the neighbours. It's general information, so check approvals and engineering for your own site with your certifier, engineer and council.

Knock-down rebuilds on the canal estates

A knock-down rebuild packs a lot into a few months: demolition, excavation for footings or a basement, sometimes piling, then a new house that often fills far more of the lot than the old one. On a canal block, all of it happens between two neighbours and a waterway.

Before demolition, capture the existing house and site. It's a measured reference for the designer, a record of what was there, and the start of the condition record for everything around it.

Three Gold Coast risks, and what a scan records

Each scenario below is a common Gold Coast job with its own risk. Select one to see what a 3D scan records before work starts, and who that record protects.

Canal frontages and the revetment wall

The revetment wall holds the canal bank in place, and the house, pool and any excavation on a canal lot sit close to it. Heavy machinery, piling and digging near the wall can move it, and building near it comes with its own setback and structural rules. Check the requirements for your lot with your certifier and the City of Gold Coast before design is settled.

A capture before work starts records the wall's face and capping, any existing cracks or lean, and the pontoon and jetty connections. If the wall is questioned later, there's a dated, measured baseline to compare against.

Zero-lot boundaries and the neighbours

Built-to-boundary walls and narrow lots put new footings, basements and pools within centimetres of the house next door. Since 1 August 2025, section 179 of the Property Law Act 2023 (Qld) has set a duty of care between neighbours for loss of support, so the neighbour's house matters before, during and after excavation.

Record the neighbouring walls, retaining walls, slabs, paving and fences with the neighbour's agreement before any excavation. Existing cracks are logged to scale, not just photographed, and the capture can be repeated after the dig for a like-for-like comparison. Lodge a free Before You Dig Australia enquiry as well.

High-rise fit-outs and the body corporate

An apartment renovation shares slabs, risers and common property with everyone else in the building. The body corporate will want to approve the works and the route materials take, and damage to the lift, lobby or the unit below is quickly disputed.

Capture the unit before strip-out, with its ceiling space and services, and the common property on the works route: the lift, lobby and corridors. The designer gets measured existing conditions for joinery and services, and the body corporate gets a dated record of the building before work started.

Booking a capture on the Gold Coast

Gold Coast captures are booked with our daily Brisbane Metro runs, dispatched from Sunshine Coast HQ. Book before demolition or excavation starts, and allow time to arrange access with the neighbours or the building manager. Every capture is architectural-grade, not a survey: boundaries and set-out are work for a registered surveyor.
