When we embarked on this journey, the most significant factor that we used to help us choose those who would ultimately complete our project, was that those involved would live and breathe our vision alongside us as it came to life. Kyle was introduced to us through our building designer, Andrew Slattery, from Anabode Design. Andrew called upon Kyle for some advice during the design process regarding value management. From that day forward, and many months before our project went to tender, Kyle was there. He consistently checked in offering advice, watching the design evolve, and all the while building our trust. Eltcon operates with full transparency, we always felt in control of our finances, our budget was respected and adhered to, small changes were never too much trouble, the team are exceptionally responsive and communicate beautifully. Everyone involved and on site displayed a genuine enthusiasm and passion for their work. We are absolutely delighted with the finished product, and visitors are always left speechless. Kyle, Jared, and team, we thank you from the bottom of our hearts for driving this dream of ours and delivering a home that has truly surpassed all our expectations.

Thanks for all of your hard work getting us into the second half of our building! Your professionalism and attention to detail were greatly appreciated. We're so excited to finally move new toys into our renovated rooms. Thanks Kyle, Jared and team.Posted on Colleen Stevens2025-01-29Trustindex verifies that the original source of the review is Google. I reached out to the Eltcon team in desperation, trying to find a commercial builder who would help us with a small renovation project at the Knox Toy Library (of which I am president). Kyle and Jared were so lovely and did everything they could to help us get through the approvals required from Council to get the job done. Their team were efficient and a pleasure to deal with. They managed to turn everything around quickly and were so patient and helpful as we navigated the approvals process. We've finally been able to open the second half of our space thanks to their brilliant work. I would highly recommend them. I'm yet to meet a more professional and experienced team. Thank you!Posted on Luciana C. Verdi2024-08-25Trustindex verifies that the original source of the review is Google. From the first interaction Eltcon understood our project and jumped on board.

Eltcon designed and built our second story renovation. From the tender process all the way through to handover Jared and Kyle have been nothing short of professional. The standard and quality of all aspects of the build have not only met our expectations but exceeded them. Having Michael and Eddie assigned as project managers meant we had a point of contact at all stages throughout the build. Eltcon have built a fantastic organisation with quality people, we cannot recommend them enough.Posted on Alex Barnes2023-08-23Trustindex verifies that the original source of the review is Google.

ARCHITECT COLLABORATIONS FOR SEAMLESS DESIGNS
Our commitment to excellence extends to close collaborations with architects. This ensures that every home extension we undertake is not only structurally sound but also architecturally cohesive, enhancing both aesthetics and functionality.
HOME EXTENSION:
Blending the old with new
Extending an existing home requires careful consideration of how the new section connects to what is already there.
Structure, levels, materials and finishes all need to be aligned so the extension feels integrated with the home rather than separate from it.
Eltcon’s in-house carpentry team supports this process, maintaining a consistent standard of workmanship and attention to detail throughout construction.


Extension Styles to Suit Your Home

Rear
Extensions
Allow homeowners to expand their living space without altering the street-facing façade of the home. These extensions often open up to the backyard and incorporate modern indoor-outdoor living spaces with features.

Second-Storey
Additions
Adding a second storey is a favored choice for many in Melbourne. This type of extension can dramatically increase the living space of a home without expanding the building’s footprint.

Side
Extensions
In areas where properties have a bit more side yard space, this type of extension is typically used to add rooms like a new bedroom, larger kitchen, or additional living areas.

Why Clients Choose Eltcon.
Clients choose Eltcon for the way extensions are delivered day to day, not just the final result.

Particular attention is given to the areas where the extension connects to the existing home, where alignment, materials and finishes need to be handled with care.
There is a clear understanding of cost throughout the build, with ongoing visibility as the project progresses. Decisions are addressed at the right time, with the information needed to move forward confidently, rather than being deferred or revisited later.
