Eco Demolition takes on knockdown rebuilds and site preparation across Castle Cove, on Sydney's Lower North Shore, as one licensed demolition contractor. We are a family-operated business established in 2015, with more than 1,000 projects behind us, and we run the whole job under one contract: the Willoughby City Council approval, the licensed asbestos removal, the demolition, then a clean, construction-ready block. In Castle Cove, NSW, the approval is the part worth getting right, because a demolition and rebuild here is often assessed closely on planning grounds.

Which approval a Castle Cove demolition needs
A demolition in Castle Cove is assessed by Willoughby City Council, under the current Willoughby Local Environmental Plan 2012 and Willoughby Development Control Plan 2023. These are the plans in force now, so check that any older advice has been updated. Which approval you need depends on the property and the scope of work, not on the suburb, and there are three broad routes.
Some minor work is exempt development and needs no application at all, provided it meets every condition in the State planning rules. Many straightforward house demolitions can run as a Complying Development Certificate, a faster code-based approval issued when a job meets the State’s codes. Anything outside those codes, such as an environmentally sensitive site or a design that pushes past a planning standard, needs a full Development Application assessed by the Council.
Often the demolition is bundled into the Development Application for the new house, so the old dwelling and its replacement are approved together; sometimes it is lodged on its own. We work out which pathway your job needs and manage the lodgement.
What sends a Castle Cove application to the Willoughby Local Planning Panel
Not every Castle Cove demolition and rebuild is signed off across the counter. When a proposal seeks to go beyond a development standard in the Local Environmental Plan, the building height limit being the common one, Council usually cannot approve it under staff delegation. It goes instead to the Willoughby Local Planning Panel, an independent panel that determines the application at a public meeting. Willoughby’s own determination reports show this on Castle Cove rebuild proposals, and at least one recent application was recommended for refusal. That does not mean your project is doomed; it means the approval is worth managing properly, with the standards understood before the design is locked in.
Two other things can move a Castle Cove job off the fast track. Some land here is environmentally sensitive: sites assessed under WLEP 2012 have carried a C4 Environmental Living zoning, so where significant trees or native vegetation are involved, Council may ask for an arborist or biodiversity assessment. And to change what is being demolished under a consent you already hold, you lodge a section 4.55 modification rather than a new application. We read the planning position up front, so none of it surprises you mid-project.
About Eco Demolition
Eco Demolition is a licensed demolition and asbestos removal contractor, family-operated and led by founder Adam A. Abbas. Since 2015, the team has completed more than 1,000 projects across residential, commercial and government sites. Our published licence numbers, ISO accreditations, insurance cover and customer reviews sit on our main Sydney demolition service, where the full credentials are set out. On a Castle Cove job, what counts is simpler: one licensed team runs the work from the Willoughby approval to handover, with a single point of contact throughout.
Asbestos, cleared before the structure comes down
If a Castle Cove home was built before the 1990s, it may contain asbestos, often in fibro sheeting, eaves, cement pipes or old floor backing. It has to be dealt with before the structure comes down, not during, so every demolition starts with a pre-demolition inspection for asbestos and other hazardous materials.
Where asbestos is present, our licensed removalists take it out first, under SafeWork NSW and NSW EPA rules, for compliant disposal at a licensed facility. It comes in two forms: non-friable, bonded into solid sheeting, and friable, which is loose or crumbling and controlled far more strictly. Friable asbestos must be removed by a Class A licensed removalist, and we hold that licence; for it, the air monitoring and clearance certificate are issued by an independent licensed assessor we arrange and coordinate, never sign off ourselves. Structural demolition begins only once the site is cleared and certified.
Knockdown rebuilds, swimming pools and the work we take on
Across Castle Cove the demand is mostly knockdown rebuilds: an older detached house comes down so a new one can go up. Swimming pools feature more often than not: sometimes the pool and its slab come out with the house, sometimes the new plans keep them and the demolition works around what stays. We take the house down safely, cap the services, clear the slab and footings, and leave a level site for the builder.
The work we take on in Castle Cove includes:
- Full house demolition and knockdown rebuild site preparation
- Partial and selective demolition where part of the building stays
- Internal strip-outs and wall removal for renovations
- Swimming pool removal and site restoration
- Shed, garage and outbuilding removal
- Site clearing, excavation and earthworks for the new build
We door-knock the neighbours before work starts, and on many Castle Cove applications they are formally notified under the Willoughby Community Participation Plan, so keeping the street informed is built into the job.
Pricing a Castle Cove demolition
There is no square-metre rate for demolition, because no two sites are the same. Your price is shaped by what is coming down and how it is built, whether asbestos is present, site access, whether a pool or basement has to come out, the approval pathway, and how much waste is carted away.
So we look at the actual site, then put one fixed price in writing. Under our Fixed Price Guarantee, the price we quote is the price you pay, with no hidden extras once work is under way, unless you change the scope. The quote is free.

Castle Cove demolition questions, answered
These questions come out of the Willoughby approval process itself on most Castle Cove jobs.
No. Some minor work is exempt, many house demolitions run as a Complying Development Certificate, and only jobs outside the complying codes need a full Development Application assessed by Willoughby City Council. We confirm which applies to your address before anything is lodged.
Because a proposal that seeks to exceed a development standard, such as the building height limit, usually cannot be approved under staff delegation. It is referred to the independent Local Planning Panel to determine. Getting the standards right early keeps a job off that path.
Often, yes. In Castle Cove the demolition is frequently bundled into the Development Application for the replacement dwelling, so both are consented as one. Where you only need the structure removed, a demolition-only application is lodged instead.
We manage it. From the site assessment to the final compliance certificates, one team handles the documents and the lodgement, so you deal with us rather than Council.
