Complete Home Extension Service
A complete home extension service manages every stage of expanding your home — from initial design and planning approval to full build management. At HomeExtensionsRUs, we coordinate the entire process, ensuring your vision for more space is delivered seamlessly, on time, and to the highest standards.
A Seamless Journey from Vision to Reality
Your home extension is one of the most significant projects you’ll undertake, and it deserves a carefully managed, end-to-end approach. HomeExtensionsRUs brings structure, transparency, and professionalism to every phase of your project – so you remain informed, confident, and in control from concept to completion.
Step 1 - Feasibility & Design Discovery
Our process begins with a detailed Feasibility Study, the foundation for every successful extension.
What this includes:
- Floor plans and layouts tailored to maximise space and functionality.
- Visual impressions that help you picture the finished extension before any work begins.
- Planning assessment aligned with local council regulations.
- Budget outline and timeline framework to keep expectations realistic.
Each feasibility study forms part of our Home Extension Design stage, where concept and practicality come together to reflect your lifestyle and vision.
Step 2 - Council Planning Approval
With your preferred design defined, our planning specialists handle the next stage — preparing and submitting the application to your local council.
This includes:
- Detailed architectural drawings developed for compliance and clarity.
- Planning documentation and statements aligned with regional regulations.
- Schedule of Works, detailing every stage of the build sequence for accountability.
Our expertise and 30+ years of experience ensure your submission is robust and complete. Learn more about how we guide this process in our dedicated Council Planning Approval page.
Step 3 - Build Project Management
Once approval is secured, we manage the build with precision and care.
Our build management covers:
- Tender coordination – sourcing and vetting trusted builders from our established network.
- Contract finalisation – ensuring all parties have clear expectations.
- On-site supervision – monitoring work quality, safety, and adherence to your specifications.
- Progress updates – keeping you informed at every key milestone.

Frequently Asked Questions - Complete Home Extensions Service
I'm feeling bit daunted by the idea of starting a home extension - where do I even begin to make sure it's the right choice for my family?
Starting a home extension can feel daunting, but it’s an exciting step toward creating space that grows with your family. Begin with a free feasibility study to assess your home’s potential and align it with your lifestyle needs, giving you confidence that the project fits your vision without overcommitting upfront.

This continuity ensures clear timelines, transparent updates, and no surprises, so you can enjoy the transformation rather than worry about it.
