Bayside Extensions & Renovations

Capital Building can give you expert and specific advice for your home and project. You can also visit: www.vba.vic.gov.au/consumers/home-renovation-essentials/permits to learn more.

Capital Building specialise in major home renovation projects. Usually including new kitchens, laundries, bathrooms and new open plan living areas. Typically, these projects will include extensions, for example a new second storey with retreat, bedrooms and bathroom and/ or a new rear extension with a open plan kitchen, dining and living.

In many cases, it is possible to stay in your home during a renovation. However, for larger projects that involve extensive construction or major disruptions, it may be  necessary to temporarily relocate.

    This is a 5-star review, and importantly, it is for a reason.

    As a very particular and fussy homeowner, I spent years searching for the right builder for our extension project. Since 2017, I had spoken with over four extension builders before finally meeting Trav and Dean and selecting Capital Building Contractors.

    One of the key things I was looking for was a builder who was approachable, flexible, and willing to listen. Extension projects are very different from brand-new builds, with many moving parts and unexpected challenges along the way, and the team handled this professionally throughout the journey. This was also a very specific build. My expectation was that the final outcome should not feel like an extension, but rather a completely brand-new home — and Capital Building genuinely helped bring that vision to life.

    Of course, like any project, there were challenges and disagreements at times, but what stood out was their willingness to discuss, negotiate, and work through issues professionally.
    The build was handed over in October 2025, but I intentionally waited before writing this review so I could properly assess their after-handover support, maintenance, and defect management — which has been excellent.

    A sincere thank you to the entire Capital Building team, especially Trav, Dean, Kyle, and Andrew, for working so closely with us throughout the project.

    Most importantly, we are extremely happy with the final outcome of what is now our dream home, and I would have no hesitation in recommending Capital Building Contractors to anyone looking for a quality extension build.

    At Executive Robes & Screens we have had a long standing relationship with Trav and his team, they are very easy to deal with in all aspects and would recommend them to family and friends for any renovation needs

    We recently completed a major renovation with Capital Building. Every staff member and contractor were a pleasure to deal with, especially Kyle who oversaw the whole project. A special shout-out to Dean for the initial design and Laura for interior design who both had fantastic suggestions and ideas for the new space. Throughout the renovation the team were quick to adapt to any challenges that arose and clearly cared about delivering a quality result. We are thrilled with our newly transformed home and are very happy to recommend Capital Building. Thank you Travis and team!
