Building Contracts Explained: How MBV Contracts Protect You When Building a Custom Home

When choosing a custom home builder in Ballarat and across the surrounding regions, most people focus on design, build quality, and reputation. While these are all essential, one of the most important — and often underestimated — elements of a successful build is the building contract itself.

At Jetsonian Constructions, we use Master Builders Victoria (MBV) contracts for all custom homes, renovations, and extensions. These contracts are widely recognised throughout Victoria as the industry standard and are designed to provide clarity, structure, and peace of mind for both the client and the builder.

Why MBV Contracts Matter for Regional and Semi-Rural Builds

Building a custom home outside of standard estates often comes with additional complexity. Sloping sites, variable soil conditions, bushfire requirements, access constraints, and planning overlays can all influence how a project is delivered.

MBV contracts are specifically structured to manage these realities. They clearly define inclusions, allowances, timeframes, progress payments, and responsibilities from the outset, helping to minimise uncertainty and reduce the risk of unexpected costs during construction.

Because these contracts are developed by experienced construction and legal professionals, they provide a practical framework that supports well-managed builds in both urban and regional settings.

Designed to Protect Both Client and Builder

MBV contracts are deliberately balanced. They are not written to favour one party over the other, but to protect the interests of both the homeowner and the builder.

For clients, this means transparency around pricing, scope, and timing. For builders, it ensures clear direction and agreed processes, allowing the project to be delivered efficiently and to a high standard. This balance is key to maintaining trust and avoiding disputes throughout the build.

Why Written Communication Takes Priority

Once a building contract is signed, written communication takes precedence over all other forms of communication, including phone calls and site discussions. This is particularly important when variations are required.

Any change to the scope of works, materials, or finishes must be documented in writing, clearly outlining any cost or time implications, and approved before the work proceeds. This process protects clients from unexpected variations and ensures there is a clear record of every decision made.

A Better Building Experience

As an experienced custom home builder servicing Ballarat and surrounding regional areas, we’ve found that clear contracts and structured communication lead to smoother builds and better outcomes.



MBV contracts help reduce stress, improve transparency, and create a more enjoyable building journey — allowing clients to focus on the excitement of seeing their home take shape.
