The house is the cheap part, until it isn't

Plenty of Geelong buyers are looking at older homes purely for the block — a tired weatherboard in Belmont, a 1960s brick home in Highton, a fibro cottage in Grovedale or Newcomb. The plan is simple: buy, knock down, build. But two blocks at a similar price can carry very different demolition bills and very different timelines, and almost all of that difference is visible before you sign if you know where to look.

This is the checklist we'd run through before buying a house to knock down. It doesn't replace your conveyancer, building surveyor or builder, but it will help you ask them the right questions.

1. Check the overlays first

Pull the free Victorian planning property report for the address. It lists the zone and any overlays, and one overlay matters more than the rest for a knockdown: a heritage overlay. Demolishing a building in a heritage overlay usually needs a planning permit as well as the building permit, and approval is not guaranteed. Parts of central Geelong, Newtown, Geelong West and Eastern Beach carry heritage controls, so if you're looking there, this is the first thing to rule in or out.

Also look for vegetation or bushfire overlays, which can affect tree removal and how the new home is built. Our guide to whether you need a permit to demolish a house in Geelong walks through the approvals in more detail — and the City of Greater Geelong and a registered building surveyor are the people who give the final answer.

2. Assume asbestos until it's checked

If the house was built before around 1990, treat it as likely to contain asbestos. That covers a big share of the stock in Belmont, Corio, Norlane, Bell Park, Grovedale and Highton. Look for:

Fibro sheeting on walls, eaves and in wet areas.
Corrugated cement roofing on the house, garage or sheds.
Vinyl floor tiles and the black backing underneath.
Old fibro sheds and garages, which are often the worst offenders on the block.

Asbestos is the single biggest swing factor in demolition cost on older Geelong homes, and it has to be removed under a licensed process before the house comes down. If you can, get an asbestos inspection done during your due diligence, or at least factor a realistic allowance into your budget. Our Asbestos-Aware Demolition & Disposal service explains how it is handled once you own the place.

3. Walk the access

Stand on the street and imagine a machine and a truck getting onto the block. Things that slow a demolition down and add cost:

Narrow frontages and side paths, common on older inner-suburban lots.
Power lines running low across the front of the block.
Street trees and nature strips that need protecting.
A steep slope, which is common around Highton and Hamlyn Heights and affects how the site is cleared and levelled.
Neighbours built right up to the boundary, which means more protection work and care.

None of these are deal-breakers, but they belong in your numbers. Our post on protecting neighbours during demolition covers what boundary-tight sites involve.

4. Count what else is on the block

A house is rarely the only thing coming out. Note every structure and hard surface: garages, sheds, carports, an old in-ground pool, concrete driveways and paths, retaining walls and big trees. Each one adds scope. A disused concrete pool, for example, has to be broken up, backfilled and compacted properly so the new slab isn't sitting over a soft spot. Our Garage, Shed & Pool Removal service covers exactly this kind of extra work.

Trees deserve their own look. Some can't be removed without approval, and a large tree close to where the new home will sit can affect both the demolition and the slab design. Ask before you assume it can go.

5. Think about services

Before any house can be demolished, power, gas, water, sewer and telecommunications have to be formally disconnected or abolished. That process runs through the utility providers, and it often takes longer than the demolition itself. It is worth knowing early whether the gas meter, power pole and water connection are where you expect, and whether the sewer runs somewhere awkward.

6. Match the demolition to your build

If you're buying to build, the demolition should be planned around your builder's program, not done the week after settlement. A block that sits empty for months can attract dumping and weeds, and a demolition booked too late holds up the slab. Our Knockdown-Rebuild Site Preparation service is built around that hand-over: footings out, debris gone and a clean, level pad ready for the builder.

Get a read before you commit

Private sales in Victoria generally carry only a short cooling-off period and auctions carry none, so the time to understand a knockdown is before you're bound. Send us the address and, if you can, a few photos of the house, sheds and access. We'll give you a practical read on what demolition would involve — asbestos, access, extra structures and likely timing — so you can go into the purchase with your eyes open.
