Who should review your building contract?

Major Domestic Building Contracts are extremely detailed, legally binding and require a complete understanding prior to signing. Ensuring that you that you understand what you are agreeing to significantly reduces the likelihood of disputes and unexpected costs down the track.

Building contracts can be split into three main parts:

  1. The Conditions of Contract: Generally based on HIA or Master Builders conditions.
  2. The Specification: Specifies in words what is included and the quality.
  3. The Plans: Architectural and engineering drawings showing what the house looks like and how the structural elements will be constructed.

If there are inconsistencies between the documentation, there is an order of precedence set out within the contract which explains which document prevails. Typically, the order of importance is the “Contract conditions” then “Specifications” then the “Plans”.


Signing the building contract can be an exciting time – it might mean that building work may soon commence on your block. However, it can also be a very stressful and overwhelming time. You may find yourself sitting in the builder’s sales office having been scheduled for a contract signing meeting. You may be asked to sign the contract then and there, and you haven’t even had a chance to read it properly yet. With all the anticipation leading up to the meeting, a part of you probably can’t wait to sign away!


Too many people sign their acceptance of the building contract on the dotted line without having examined it first and this can lead to unwanted surprises, stress and disappointment later. This is the most important (both contractually and financially) document you may ever sign, so it is imperative that you take the time to thoroughly go over the contract and understand it – there is no need to rush this step. Even if it takes an extra week, this is insignificant and in the long run and could save you a lot of head/heart aches.


Request that your builder emails a copy of the completed contract and all relevant documentation prior to attending the meeting. Go over it with a fine-tooth comb as once the contract is signed, even the smallest changes can result in costly variations. Ensure that what you have agreed upon with your sales representative is reflected in the contract with no discrepancies.

In addition to looking it over yourself, an independent contract review prior to signing will assure that your contractual documents are in line with industry standards. It will also identify items that require clarification and ensure that you feel confident before you commit to one of the biggest financial contracts of your life.


A lawyer or solicitor will be helpful for reviewing the contract from the legal perspective however when it comes to construction knowledge, their experience can be limited. For example, reviewing construction drawings and level surveys to determine suitable allowances for site costs i.e. retaining walls/drainage in relation to falls of the land may not be their strong suit.

Conveyancers are another profession that is commonly asked to look over building contracts because they review the contract of sale when the land is purchased to build on. Building contracts are very different to a land sale and therefore conveyancers will generally refer you onto someone more suited in this area. Similarly, if we were asked to review a contract of sale or real estate agent’s agreement, we would recommend you talk to your conveyancer.
