A knockdown rebuild in Liberty Grove costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, City of Canada Bay Council approvals, and construction under one fixed-price contract.
Demolish and Rebuild in Liberty Grove
A knockdown rebuild in Liberty Grove is almost never the right move, because the stock is too young. This is a 1990s to 2000s master-planned gated community on the former Olympic site, so the homes are modern contemporary villas and townhouses that are far too new to knock down. A renovation or reconfiguration makes far more sense than a rebuild here, and I would rather tell you that than knock down a serviceable home.
On top of the age, Liberty Grove is a master-planned R3 community with tight 200 to 400m² blocks and body-corporate-style controls, which further constrains any wholesale rebuild. Where an interior no longer fits, an internal renovation or reconfiguration is the practical path.
What I check first on your Liberty Grove property: the age of your home, which almost always points to a renovation over a rebuild, and the master-planned community controls. Those confirm the realistic path.
We build and renovate fixed-price, licence HBL 487805C. If you were thinking knockdown, let me show you why a renovation is the right play here.
Buildana manages the complete knockdown rebuild process in Liberty Grove — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Too young to knock down
Liberty Grove was built in the 1990s and 2000s as a master-planned gated community on the former Olympic site, so the stock is modern and generally sound. Knocking down a contemporary villa or townhouse of that age rarely makes financial sense, and a renovation or reconfiguration achieves far more for far less. So the honest answer here is usually not to knock down.
I would rather give you that read than sell you a rebuild on a home that has decades of life left in it.
Master-planned constraints
Beyond the age, Liberty Grove is a master-planned R3 community with tight 200 to 400m² blocks and community controls, which further constrains any wholesale rebuild. Where the interior no longer suits, an internal renovation or reconfiguration is the practical, value-adding path. I assess what the community controls and your home allow as part of the feasibility.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free site inspection of your Liberty Grove property. We check lot dimensions, City of Canada Bay Council's planning controls, existing home condition, and potential asbestos. Written assessment with budget estimate within 5 business days. KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱The Liberty Grove construction phase. Fixed price, programmed, supervised. Licensed demolition of existing 1990s–2000s master-planned-era dwelling. Asbestos removal by certified contractors (if present). Site cleared, levelled, and ready for new slab. Typically 1–2 weeks. Your new home goes up on the cleared site. Engineered slab sized for Class M–H soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping. Quality inspections at every stage.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
