Knockdown-Rebuild on the Surf Coast: What to Know Before You Start

The demolition is stage one of your new home

On the Surf Coast — Torquay and Jan Juc especially — knockdown-rebuild has become the default way to get a modern home on a good block. An original beach shack comes down and a new house goes up in its place. It's easy to think of the demolition as a small preliminary, but it's the first stage of the build, and getting it right sets up everything that follows.

Timing is everything

A knockdown-rebuild demolition isn't judged only on how cleanly the old house comes down — it's judged on whether the block is ready when the builder needs it. Too early and the block sits empty for months; too late and the trades are waiting. The demolition should be planned backwards from the build program so the site is builder-ready on schedule.

Builder-ready, not just empty

An empty block isn't the same as a builder-ready one. The old footings and slab need breaking out, all structure and debris cleared, and the ground left clean and level so the new slab isn't held up by extra site works. Ask what "site prep" actually includes before you compare quotes.

The coastal catches

Two things bite on the Surf Coast more than inland:

• Asbestos. Most pre-1990 shacks contain it. It must be removed under a licensed process and disposed of legally before demolition — a real cost and a real timeline item, not an afterthought.
• Overlays. Bushfire, vegetation, landscape and heritage overlays are common from Torquay's fringes through Anglesea, Aireys and Lorne. Where they apply, a planning permit may be needed on top of the building permit. Flagging them early keeps them from derailing the timeline.

Working around the Surf Coast seasons

Torquay and Jan Juc don't run at the same pace all year. Over the summer holidays and the busy long weekends the streets fill up, parking disappears and trucks have a harder time getting in and out of narrow coastal streets. If your rebuild timeline gives you a choice, it's worth talking about when the demolition lands relative to that peak. It's worth thinking about the neighbours too, because many of the houses around you may be holiday homes that are full in January and empty in winter. None of this rules out a summer demolition, but it changes how the access is planned.

What your builder will want at hand-over

Most builders have a short list of things they need from the demolition before they can start. Agree it up front so nothing is discovered on the day:

• Levels and boundaries. Whether the surveyor needs any existing levels or pegs left, and where the boundaries sit relative to the new slab.
• The crossover and driveway. Whether the existing crossover is staying for site access or being replaced, and whether any of the driveway is kept as a temporary hardstand.
• Trees and vegetation. Exactly which trees are staying and how they're being protected — on the coast this often ties back to an overlay.
• Site fencing. Whether the demolition fencing stays up for the builder or comes down.
• Underground surprises. Old pipes, stormwater pits or disused tanks found during the slab break-out, so the builder knows what was there.

Sand, slope and fill

Surf Coast ground varies more than people expect. Parts of Torquay sit on sandy soils that are easy to dig but don't hold a clean edge, while Jan Juc and the streets climbing away from the beach bring slopes that make "level" a design question rather than a given. Some older blocks also carry fill from earlier works. Your builder's engineer designs the new slab around the ground, and the demolition should leave the site in a state that suits that design — cleared back to natural ground where needed, not with loose rubble pushed into the low corner. Ask your builder whether soil testing is planned before or after the demolition, as it can affect how the block is left.

Holiday homes and owners who live elsewhere

A lot of Surf Coast knockdowns are run by owners who live in Geelong or Melbourne. That works fine, but it means access, keys, the utility abolishments and neighbour notices need someone looking after them. Ask for photo updates at the key stages — asbestos cleared, structure down, site handed over — so you're not driving down the coast just to check progress.

Get the demolition scoped early

Even before the builder is locked in, getting the demolition scoped and quoted removes one unknown from the rebuild. Send the address and a bit about the house and we'll give you a read on the demolition, the likely asbestos position and any obvious overlay issues — see our knockdown-rebuild service and our Surf Coast permit guide.
