The 5J Building Group Difference

In addition to our high-quality work, our dedication to our clients sets us apart. We strive to listen to your dreams and make them a reality. Before we even start the renovation, our design consultants will listen to your ideas and incorporate them into a cohesive design, using the latest technology to ensure accuracy. When you hire us for your home extension Melbourne, you don’t have to hire tradespeople as well.

We come with all the necessary tradespeople to get the job done. Our people are highly trained so you don’t have to worry about a thing – they will be polite and careful with your belongings, ensuring they clean up after themselves when the job is complete. We understand your time is valuable and don’t intend to waste it. So, before we start the extension, we will give you a clear timeline of how long each process will take.

We will arrive on time every day to do the work and will promptly inform you of any challenges that crop up along the way. That’s the 5J Building Group difference.

Melbourne Home Extension Process

We keep things simple and promote transparent communication throughout every stage of your home extension. Melbourne residents have turned to 5J Building Group because we consistently deliver breathtaking results for our clients. To continue to set new benchmarks in home extension projects, every aspect is diligently managed and our services are tailored to each individual project. But there is a process we follow before commencing every project:


This is a free service that we offer to all our clients. Our in-house designers sit down with you to discuss your ideas. Your visions and goals are combined with our design team’s wealth of knowledge to come up with robust designs.


After the design is complete, our specialists come up with the working drawings that the builders will need for your home extension Melbourne project.

Plans and permits service

At this point, we will help you get all the permits and reports needed for the project. These may include building permits, soil reports and even bushfire reports. Essentially, we will deal with the council on your behalf and ensure we abide by all the necessary regulations so that you never have to worry about it.

Contracts and constructions

Before we start construction, we will give you a contract with all the necessary terms. This will give you a rundown of the project timeline, the fixed rate you will be paying, and the assurances that we are providing. Once you sign it, we will begin the actual construction and keep you in the loop every step of the way.
