Custom home builds

Whether you want to transform a tired home into a modern oasis, build up or out for your growing family or create your dream custom home from scratch, we’ll deliver a flawlessly built home you’ll love to spend time in and show off to family and friends.

Thanks to our flexible approach and extensive experience, we can build to any specifications and style—from period renovations to contemporary new builds. We can also collaborate with your chosen architect or recommend a trusted design partner for your job. We’ll work with you and your architects or building designers to ensure your needs are met and your design brief is delivered.

“We were highly satisfied with GMAC’s performance. Greg and his tradesmen were personable and easy to work with. Greg was always a helpful member of the construction team and we were pleased he worked daily on the project without juggling other projects.
It was especially pleasing to achieve the task in good time, during the exceptional difficulties presented by COVID-19 restraints.”

The step-by-step building process

Here’s what to expect from our stress-free process of working together to bring your dream Melbourne home to life.

1.Initial chat

Get in touch with us for an initial chat about your project—either before you’ve chosen a building designer or when you have endorsed plans from your architect. If you haven’t already chosen your architect, we’re happy to recommend one of our trusted partners.

2.Custom proposal

Once you have your endorsed plans from your architect, send these to us so we can put together a custom proposal and quote.

3.Meet and greet

We’ll arrange a convenient time to meet to get to know each other and discuss your project in more detail.

4.Sign contracts

Once you’re happy with everything in your project proposal, both parties will sign our contract, and we’ll organise your building permit.

5.Build and project meetings

We’ll start your build at the agreed time, with fortnightly site meetings initially to track progress, answer your questions and discuss solutions for any issues. Once the build is well underway, our site meetings will be every three to four weeks, depending on your project scope and the finishing in progress.

6.Project sign-off

We’ll invite you to the final site meeting and build sign-off, with a handover package for all appliances and certificates of compliance. Now, you can move into your beautiful new or refurbished home!
