Navigating Building Disputes in NCAT

Hammond Nguyen Turnbull recently acted for homeowners in a contested building dispute before the NSW Civil and Administrative Tribunal (NCAT), resulting in a money order in favour of the clients.
The matter concerned defective residential building work carried out under a renovation and extension contract. Following a fully contested hearing, the Tribunal found in favour of the homeowners on every disputed defect item, preferring the evidence and methodology of the homeowners’ expert over that of the builder. The Tribunal also preferred a money order over a work order.
Key Findings
The Tribunal accepted that the builder breached statutory warranties under the Home Building Act 1989 (NSW), including failing to:
- Perform work with due care and skill
- Carry out work in accordance with approved plans and specifications
The Tribunal rejected the builder’s request to rectify the works themselves and instead awarded a money order, allowing the homeowners to engage alternative contractors. In considering whether a work order or money order should be granted, the Tribunal considered a money order to be the preferred outcome in consideration of:
- The builder not evidencing any measures put into place to avoid the defective works occurring again;
- The lack of communication from the builder prior to the commencement of the proceedings; and
- The lack of confidence that the builder would ‘do the right thing’.
Expert Evidence Was Critical
The Tribunal accepted the homeowners’ expert evidence in full, describing the expert as “impressive” and noting his detailed methodology, practical experience, and reliable costings. The builder’s expert evidence was given significantly less weight.
This decision highlights the importance of early expert engagement and strategic case preparation in building disputes.
Why This Decision Matters
This case reinforces that:
- Builders must strictly follow approved plans unless a written variation exists
- Defective work does not need to cause water ingress to breach statutory warranties
- Rectification by the builder is not automatic where confidence has broken down
- Well-prepared claims supported by expert evidence can succeed
