Oikos Constructions Pty Ltd t/as Lars Fischer Construction v Ostin

The appeal before the New South Wales Court of Appeal concerned a dispute between Oikos Constructions Pty Ltd (trading as Lars Fischer Construction) and Ostin, relating to building works. The core of the disagreement centred on whether a contract for building works was limited to a specifically negotiated scope or if it encompassed additional works by virtue of implied statutory warranties under the *Home Building Act 1989* (NSW), and whether the builder had breached these warranties.

The Court of Appeal was required to determine the extent of the contractual obligations, specifically whether the statutory warranties implied into the contract expanded the scope of works beyond those expressly agreed. Furthermore, the Court had to consider whether the building works, as performed, constituted a breach of these statutory warranties. A related issue was the assessment of damages, specifically whether the loss claimed by the respondent would have been suffered even if the contract had been properly performed.

The Court found that the statutory warranties did indeed extend the builder's obligations beyond the negotiated scope of works. It reasoned that the *Home Building Act 1989* (NSW) imposes certain minimum standards and obligations on builders, which are incorporated into building contracts regardless of the express terms. The Court analysed the evidence to determine if these statutory obligations had been breached. The Court allowed the appeal in part, setting aside the original District Court judgment and directing entry of judgment for the respondents against the appellant in the sum of $35,548.58, with provisions for repayment of excess moneys paid and interest. The Court also made orders regarding the costs of the appeal and reserved the question of costs for the proceedings below.
