Home extensions, carefully planned and built around the way you live.
Good home extensions start well before construction.
Extending an existing home comes with its own challenges. Structural connections, site access, existing conditions and design decisions all need careful consideration before construction begins. Getting a builder involved early can make a significant difference.
Starting early? Rival works alongside your architect or designer to review the proposed extension, consider construction requirements and align the design with your budget.
Already have plans? We'll review the documentation, identify potential construction challenges and prepare a detailed fixed-price proposal for your home extension.
- Early input or plans-ready renovation pricing
- Practical advice on structural alterations and buildability
- Hands-on builder involvement from planning to completion
Complete Clarity
We'll discuss your home extension plans, goals and budget, whether you're just starting out or have drawings ready. It's an opportunity to understand the scope, see if we're the right fit and agree on the next steps.
We visit your property to discuss the proposed extension and assess site access, existing structures and how the new addition will connect with your home. We'll identify potential construction challenges early.
If you're starting early, we work with your designer to align the extension with your budget and construction requirements. If your plans are ready, we review them in detail and prepare a comprehensive fixed-price proposal.
Our dedicated team manages your home extension from start to finish, with hands-on builder involvement, clear communication and careful attention to integrating the new spaces with your existing home.
Our Commitment
We believe every home extension deserves the time, care and attention it takes to do it properly.
Extending an existing home requires careful planning, practical problem-solving and an understanding of how new construction integrates with the original building. It's work we genuinely enjoy, and something we take pride in getting right.
Rather than taking on more work than we can properly support, we deliberately limit the number of projects we undertake. This allows me to remain personally involved on site, working closely with our carpenters, clients, architects and designers throughout construction.
For us, success isn't measured by the number of extensions we complete. It's measured by the relationships we build, the experience we provide and the homes we're proud to hand over.

Frequently Asked Questions
No. Some homeowners contact us with completed architectural plans, while others are still exploring their extension options. We can work alongside your existing architect or designer, or introduce you to suitable design professionals. Involving a builder early can help assess structural requirements, site access, construction feasibility and budget considerations before the design is finalised.
The cost of a home extension in Melbourne depends on its size, structural requirements, site conditions and level of finishes. Ground-floor and second-storey extensions can vary significantly in complexity, particularly when alterations to the existing home are involved. At Rival, we generally undertake substantial extension projects with budgets from $400,000, with larger or more complex projects exceeding $600,000. We provide detailed fixed-price proposals once the plans and specifications are finalised.
Yes. Once your extension plans, engineering and specifications are sufficiently detailed, we prepare a comprehensive fixed-price proposal. The scope, inclusions, exclusions and any necessary allowances are clearly documented before signing, so you understand the agreed works and costs. Any unforeseen conditions or changes during construction are managed through the contract variation process.
We build across Melbourne’s eastern and inner-eastern suburbs, with projects considered elsewhere where they’re the right fit. If you're outside these areas, get in touch and we'll let you know if we can help.
We'll arrange an initial discovery call to discuss your existing home, extension plans, budget and anticipated timeframe. If the project is a good fit, we'll organise a site consultation to review the property, discuss any construction considerations and establish the next steps towards planning and pricing your renovation.
