Partial demolition removes part of a building and keeps the rest standing and usable. In Bendigo that usually means taking off a rear lean-to before an extension, opening up internal walls, removing a failed verandah, or stripping a kitchen and bathroom back to the frame before a renovation. A strip-out is the internal version: linings, fixtures, cabinetry and floor coverings come out, and the structure stays.
This work is more delicate than knocking down a whole house. A machine cannot simply push through, because what remains has to stay sound, weatherproof and safe. This page explains the approvals, the risks and what to ask, so that the business you are connected with can price the job properly. Bendigo Demolition Service is a referral service and does not carry out the work itself.
Common partial demolition jobs around Bendigo
- Rear additions on period homes. Many weatherboard cottages in Golden Square, Ironbark and Quarry Hill carry later skillion additions with low ceilings and tired wet areas. Removing these is a common first step before a new rear extension.
- Opening up the plan. Taking out walls between kitchen, dining and living areas. Some of those walls carry roof loads, and an engineer has to specify a beam before anything is cut.
- Verandahs and carports attached to the house. These are often rotted posts or sagging roofs that need to come off before rebuilding.
- Renovation strip-outs. Kitchens, bathrooms, laundries, ceilings and floor coverings removed back to the frame so trades can start.
- Fire, storm or water damage. Damaged sections are cut out so an insurer's builder can reinstate them.
Approvals for partial work in Victoria
Not every strip-out needs a permit. Removing non-structural fittings inside a house is usually treated as renovation work. Structural removal, work on external walls, and anything that changes the street-facing facade is different. The section 29A volume test looks at all demolition on the building over the previous three years combined. So a series of small removals can add up to the 50 per cent threshold, and any work on a street-facing facade, verandah or roof plane triggers report and consent no matter how small it is.
This is where Bendigo's heritage controls matter. In a Heritage Overlay, demolishing a front verandah, chimney or part of the roof normally needs a planning permit, even when the rear of the house can be changed more freely. The City of Greater Bendigo's heritage design guidelines show how much weight the council gives to verandahs and front facades in goldfields streetscapes. A building surveyor can confirm what applies before you commit to a design.
Structural safety
Because the remaining building has to stand up, partial demolition depends on sequence. Typical controls include:
- engineering advice on beams, temporary props and bracing before load-bearing walls are removed;
- isolating electrical circuits and capping plumbing in the area being removed, while the rest of the house stays live;
- keeping the house weatherproof, with tarps or temporary walls, because Bendigo storms can arrive quickly in spring and summer;
- separating the work zone from occupied rooms if people are still living in the house;
- hand demolition where a machine would put the remaining structure at risk.
Ask any contractor how they will keep the remaining house stable and watertight between demolition and rebuilding. If the builder is not lined up to start soon after, someone has to own that gap.
Asbestos in partial jobs
Small sections of older houses are exactly where asbestos tends to hide. Look in bathroom wall sheets, eave linings on additions, vinyl tiles under carpet, the backing of meter boards and old flue pipes. Victorian rules require asbestos in the area to be identified and, where reasonably practicable, removed before demolition starts. An unlicensed person may only remove up to 10 square metres of non-friable material within a set time limit. Anything more, or any friable material, needs a licensed removalist. If an asbestos inspection has not been done, ask for one before the strip-out is priced.
Typical sequence
- Walk-through to agree exactly what goes and what stays, ideally with the builder or designer present.
- Asbestos inspection, plus engineering advice for any structural element.
- Permits and consent, where triggered.
- Make-safe: services isolated, protection laid over floors that are staying, and dust screens installed.
- Hand and small-plant removal in the agreed order.
- Waste sorted, with recyclable metals and timber separated.
- Temporary weatherproofing and handover to the next trade.
What drives price
Partial demolition is usually priced on labour and disposal rather than square metres. Hand work, protection of the retained areas, tight access, asbestos, and small loads to the tip all add time. A rear lean-to and wet area strip might be a few days' work. A full internal strip of a large villa is considerably more. Ask for inclusions and exclusions in writing, especially for making good the remaining structure.
Strip-out versus partial demolition versus renovation builder
If your builder already holds the renovation contract, they may handle the strip-out with their own crew or a subcontractor. A specialist is worth considering when the strip-out is large, has asbestos, needs out-of-hours work, or must happen before the builder is appointed. In Victoria, a builder who manages demolition as part of a larger renovation still needs the demolition itself done by someone appropriately registered.
Frequently asked questions
Do I need a permit to remove an internal wall?
If the wall is non-structural, often not. If it carries load, an engineer and a building permit are normally involved. Your building surveyor can confirm before you start.
Can I stay in the house during a partial demolition?
Sometimes, for a contained rear addition or a single room. Dust, noise and services being switched off make it hard for longer jobs, and asbestos removal usually means keeping people out of the area.
Does removing a front verandah need council approval?
In Victoria, removing any part of a street-facing facade, including the verandah, triggers section 29A report and consent. In a Heritage Overlay, a planning permit is usually needed as well.
Who makes sure the rest of my house does not fall down?
The demolition contractor follows engineering advice and a safe work method. The designer or engineer specifies supports. Ask who is responsible for temporary propping until the new structure goes in.
How is a strip-out priced?
Usually by the scope and time involved rather than by area: the labour, the bins or truck loads, and any asbestos or protection needed. An itemised quote makes comparison easier.
