Capability · Builder takeover
Finishing what someone else couldn't.
Diagnostic site audit, contract closeout, defect rectification, and completion to PC. The conversation almost no client wants to have — and the one we run more of than you'd expect.
The situation we walk into
A Sydney homeowner is 9 months into a build that should have been done. The builder hasn't been on site in 3 weeks. The site is half-locked-up. There are unpaid subcontractors threatening Security of Payment Act claims and statutory liens. The architect is frustrated. The certifier hasn't been called for an inspection in two months. The client is paying interest on a construction loan with no end in sight. This is the call we get on average once a month. Sometimes the previous builder is still technically engaged but non-performing; sometimes they've effectively walked; occasionally they've gone into voluntary administration and the project is frozen pending creditor sign-off. Either way, getting from where the project is to a finished, certified home takes a specific kind of work that most builders don't want to do.
Why most builders won't take these jobs
Inheriting half-built work is risk-dense. You don't know what's been done correctly behind the plasterboard you can't see. You don't know whether the structural steel was installed per the engineer's drawings or to whatever was on site that day. You inherit any defects the previous builder caused — and HBCF insurance won't always cover defects from the prior contract. The legal closeout with the previous builder is messy and time-consuming. Subcontractors who were burned on the previous contract are wary of starting again. The client is exhausted, distrustful, and broke. Volume builders walk away. Builders who specialise in new builds find it culturally incompatible with their systems. The work goes to a small group of Sydney builders willing to do forensic intake work and accept compressed margins on the rest.
The diagnostic step
Before we quote anything, we do a structured site audit. Physical condition of every trade's work, room by room — what's been completed correctly, what's been completed incorrectly, what's been left. Contract status with the previous builder — original contract, variations to date, payment certificates issued, retention held. Payment status with subcontractors — who's owed what, who's filed Security of Payment Act claims, who's likely to. Certifier and council compliance position — outstanding inspection requirements, mandatory hold points missed, occupation certificate pathway. Defect register against what's been built — usually by a building consultant, sometimes by the architect if they're still engaged. Realistic program to completion. The output is a written report — sometimes that report tells the client to negotiate with the original builder rather than switch, because the lift-and-shift cost exceeds the value of leaving. We charge a fixed fee for the audit and we'll tell you the truth, not what gets us the next contract.
How the takeover actually works
If a takeover is the right call, we work with the client's solicitor to close out the previous contract cleanly. That involves either negotiated termination (where the previous builder agrees), termination for breach (where they don't), or termination under the contract's frustration / insolvency clauses (where they've gone bust). Security of Payment Act adjudications often need to be defended or paid out before we can engage the previous subcontractors. Retention release from the previous contract requires either agreement or arbitration. The HBCF claim — if there is one — runs in parallel through icare HBCF (the NSW insurer) and your solicitor, not through us. Once the contract is clear, we re-tender or directly engage the trades needed to complete. We accept the defect register the diagnostic produced and rectify it as part of the program. And we run the rest of the project as our own — director on site, weekly reporting, fixed-price where possible.
HBCF, statutory warranties, and what survives the takeover
Two important things to understand. (1) The NSW Home Building Compensation Fund (HBCF) covers residential work over the cover threshold — if the previous builder is insolvent, has died, or has disappeared (the three statutory triggers), the homeowner can claim against the HBCF policy that was in place for the original contract. The claim covers the cost to complete the work to the original contract value, plus rectification of defects, capped at the policy limit. The claim itself runs through icare and your solicitor. (2) Statutory warranties under the Home Building Act 1989 (Pt 2C) run with the work itself, not with the builder. So defects in work done by the previous builder remain claimable against that builder (and their HBCF insurer) for 6 years (major defects) or 2 years (minor defects) — even though they're no longer on site. When we take over, we issue a new HBCF policy for the remaining contract value, and our statutory warranties cover the work we do, not the previous builder's work. The legal interaction matters — work with a solicitor familiar with residential building claims.
How Varloch approaches builder takeover
We treat the audit as a separate engagement from the build. You can pay for the audit, take the report, and use it to negotiate with the original builder, take it to a different builder, or shelve the project — your call. If you choose us for the build, the audit fee is credited against the build contract. We document the existing condition photographically before we start, room by room and trade by trade, so the boundary between 'previous builder's work' and 'our work' is unambiguous when warranty claims arise later. We don't accept hidden defects as our own — they're flagged in the contract scope and tracked as a separate risk register. And we keep the lines of communication open with the architect and the certifier from Day 1, because they've usually been operating without clear builder communication for months and need a reliable point of contact.
Frequently asked
Do you take on jobs where the original builder is still on site?
Only where the client has formally terminated or is in active termination with the previous builder. We won't run a parallel contract. The legal cleanup has to happen first.
What does the diagnostic audit cost?
Fixed fee depending on project size — typically $4,000–$12,000 for a Sydney residential build. It produces a written report you can take to your solicitor and your bank. If you proceed with us for the build, the audit fee is credited against the contract.
Can you make a HBCF claim against the previous builder?
We can support your claim with documentation. The claim itself runs through icare HBCF (the NSW insurer) and your solicitor — it's a statutory claim by the homeowner, not by the new builder. We've helped clients run successful claims before, but the legal path is theirs.
Will the completed home still be eligible for HBCF insurance?
Yes — when we take over a residential build, we issue a new HBCF policy for the remaining contract value. This is the way the NSW scheme is designed to work for builder substitutions.
What about defects in the previous builder's work?
Two parallel paths. (1) Cosmetic and accessible defects we'll rectify as part of the takeover scope at agreed cost. (2) Structural or non-accessible defects (e.g. inside walls, in slab, in roof structure) are flagged in the contract scope and tracked as a separate risk register — you can pursue these against the previous builder under the statutory warranties (6 years for major, 2 years for minor) or against their HBCF policy if applicable.
How long does a typical takeover add to the original program?
The audit itself is 1–2 weeks. Contract closeout with the previous builder usually runs 4–12 weeks in parallel with our preparatory work. Once we start on site, we're typically completing in 80–120% of the time the previous builder had remaining — not faster, because forensic intake work and defect rectification absorb time the original program didn't account for.
Will my construction loan extend to cover the takeover?
Usually yes — most major banks have specific processes for builder substitution and HBCF replacement, though the loan may need re-documentation. Talk to your lender early; they're usually accommodating when the alternative is a stalled half-finished asset on their security.
Can we keep using the architect, engineer, or certifier?
Yes, and usually we recommend it. Continuity reduces re-documentation costs and preserves design intent. We re-engage with each professional on the existing fee schedule (or a renegotiated one if their scope has changed).
