As Perth Construction Lawyers, we specialise in all building and construction contract advice, dispute resolution and litigation matters.

We act for builders, developers, sub-contractors, engineers and architects as well as owners of residential and commercial property on all building contract and payment disputes. We advise on all Building and Construction contracts including Australian Standards and HIA contracts.

We also handle disputes over building contract price increases for residential and commercial matters.

We know the WA construction industry, the contracts in use and the issues that arise in constructions works.  We’ve done this work for 25 years.  The advice we provide is not just legal advice.

We provide top tier services and top tier experience at substantially better rates to those of our competitors and we provide fixed fee costs wherever possible for all of our matters.

Our rates and fixed prices for commercial work and for building and construction matters are therefore lower than the prices charged by many Perth Commercial law firms.

We often can perform this type of work for a fixed fee.

Lump Sum Home Building Contracts – Can the price be increased?

Since the introduction of the Federal HomeBuilder and WA Building Bonus grants, there have been issues relating to delays in the construction process and claimed increases in builders’ costs, which we have seen builders look to pass on to owners under their building contracts.

Whilst the widely used Lump Sum Building Contract specifies a price for home construction, there are clauses that allow builders to increase the so-called ‘lump sum’ price in specific circumstances.

Owners are often unaware of these price increase clauses, their rights, and the process to dispute a price increase notice from the builder. If owners want legal advice on disputing a price increase notice they should seek that advice urgently, as there are strict time limits for the dispute process. Read more at Lump Sum Home Building Contracts.

See Building and Construction for more information. Department of Mines, Industry Regulation and Safety have also issued a helpful guide – A Guide on price increases to home building work contracts.

We advise clients before they sign building contracts on important terms and help clients having problems with their builders.
