Our House Extension Process

We don’t just build extensions; we design additions that seamlessly integrate with your existing house, creating a space that feels designed for your life. We take the stress out of the entire process, managing everything from initial design consultations to final construction. Our team comprises highly skilled architects, building designers, experienced builders, and project managers, all dedicated to exceeding your expectations. We believe in clear communication and fixed-price contracts, ensuring you stay informed and in control of your budget. Since 1994, we’ve helped countless Melbourne families unlock the potential of their properties.

Following the initial consultation, if you choose to proceed, we’ll move into the design development stage. The initial meeting with your professional home extension designer is at no charge. This collaborative process involves working closely with our building designer to refine your vision and translate it into detailed plans with a functional and aesthetically pleasing design. We believe in open communication and encourage your active participation throughout this stage. Our building designer will present you with creative concepts that maximise the features of your existing home and optimise space utilisation. They might suggest tweaks to improve flow, enhance liveability, or introduce additional features you may not have initially considered. However, your vision always remains the priority, and we’ll ensure the final design reflects your style and preferences.

Once the design is finalised, our team of in-house registered building practitioners will draft comprehensive working drawings. These detailed plans provide our experienced builder with a clear roadmap for the construction phase, ensuring your house extension project is built precisely to your specifications. By having a team of trusted specialists readily available, we eliminate the need for you to source and manage external draftspeople, saving you time and simplifying the process.

Navigating building regulations and securing permits can be a complex and time-consuming process. At Extensions Unlimited, we take the burden off your shoulders. Our experienced team will handle all permit applications and negotiations with your local council on your behalf. This includes obtaining a building permit, securing any necessary reports like soil and bushfire assessments, and ensuring your proposed project complies with all relevant regulations. All associated fees are included in the fixed price of your extension, so you can rest assured there are no hidden fees in the final cost.

At Extensions Unlimited, we prioritise best building practices and client protection. When you choose us for your house extension projects, you benefit from the following assurances. We utilise industry-standard HIC6 contracts, guaranteeing a fixed project cost, a clear start and completion date, and clear outlined terms for both parties. Your proposed project will be fully covered by all necessary insurance policies, providing peace of mind throughout your home extensions process. Upon project completion, you’ll receive a warranty insurance certificate, offering additional protection for your investment.

Our unique three-stage contract approach ensures transparency and minimises risk for you. Stage 1 Design & Development: This initial stage focuses on refining your design, finalizing specifications, and providing a detailed cost estimate. Once you’re happy with the design and pricing, you’ll be invited to proceed to Stage 2. Preliminary Works Agreement: This stage involves securing all the necessary reports and approvals required by law before finalising the contract. This may include soil tests, engineering assessments, energy reports, and local council planning feedback. Extensions Unlimited will manage the entire process, ensuring all reports are obtained efficiently and meet council requirements. Stage 3 Final Contract: Following the completion of Stage 2, you’ll receive the final contract outlining the agreed-upon design, specifications, fixed price, and timeline for your house extension project. Once you’re fully satisfied and ready to proceed, signing the final contract signifies the official commencement of your extension project.

The construction phase is where your vision becomes a reality. Our team of experienced builders will bring your house extension project to life. We take pride in using high-quality materials and employing exceptional building practices to ensure a flawless and high-quality extension. Throughout the construction process, we prioritise clear communication and keep you informed of progress with regular updates. You’ll have a dedicated project manager as your point of contact, readily available to address any questions or concerns you may have.

We ensure all our tradespeople are fully trained and have completed an occupational health and safety course. All our constructions are regularly inspected by independent surveyors who issue reports during the progress of the works, as well as a final certificate upon completion.

All our electricians and plumbers are fully certified and licensed to ensure the highest calibre work. Our company project managers are qualified professionals who are always available for you if you have questions. Any required scaffolding will be erected by qualified riggers to ensure safety for you and your family. Company tarpaulins are also used to protect your home and the new addition.

Once your house extension is complete, it’s time to experience the joy of your new living space. We’ll conduct a final walkthrough with you to ensure everything is completed to your satisfaction and address any minor adjustments. Once you’re happy, we’ll officially hand over the keys to your dream extension.
