Building & renovation

Elevating Builder Craftsmanship

The cheapest quote rarely tells the whole story. Building a home is more than a set of numbers... it’s a relationship, a process and a commitment to quality. Choose a builder who will protect your vision, communicate clearly and care about the details that make your home unique.

Who I help

I work with people ready to make more of their home - from considered renovations and character restorations through to full home transformations and new builds. Whether it’s your first project or your third, I work closely with our clients to create spaces that reflect how they live, with thoughtful design, quality craftsmanship and a focus on the details that matter.

The problem I solve

I help take the uncertainty out of building and renovating. By combining strong project management, clear communication and a close understanding of each client’s vision, we provide the guidance and confidence needed to navigate the journey from concept through to completion.

My point of difference

I bring a combination of project management experience and a strong creative eye to every build. Working directly with each client alongside my husband and our build team, I bridge the gap between the creative vision and practical delivery - understanding the finer details, keeping the project moving and ensuring the original vision is carried through. From the bigger picture to the small details, I help create an enjoyable, well-managed experience for our clients and a high-quality finish on every project.

My niche market

We have a focus on restoring and reclaiming elements, thoughtfully integrating them into both existing and new buildings to preserve character, enrich detail, and create a sense of enduring quality.

Testimonials

"We cannot talk highly enough about Ruben and his Team at 9 House Construction. For the last four years Ruben, Jordan, Jackson and Logan have been involved with two major projects of ours including our family home which we lived in during major renovations throughout the course of a year. The 9 House Team made this possible by taking responsibility for managing the site and minimising the impact on our busy family. They are a completely reliable, tidy, extremely thoughtful, courteous and very entertaining team for whom nothing ever seemed too much trouble. Complete craftsmen with impeccable work, proactive in their care for our 100 year old villa, the 9 House Team were hands down our favourite tradespeople to have on site and in fact we have missed them now the work has been done. We unreservedly recommend Ruben and Team for any building project and would be happy to be contacted via Ruben for further verbal feedback". - Johanna & Kevin Karpik "As an interior designer, I’ve had the pleasure of working with many builders over the years - but the team at 9 House truly stands out. Their communication is clear, consistent, and professional, and their workmanship is second to none. What sets them apart is the trust they build with both myself and my clients. I’m able to hand over the build phase with total confidence, knowing they’ll deliver on the vision with care and precision. Working with 9 House makes the entire design-to-build process seamless, and I couldn’t recommend them more highly." - Melanie Sa'U "We were looking to create some usable spaces in our home that had been built as alcoves and dead space. We consulted 9 House on our ideas and they jumped into action providing a quote and linking us to work with their preferred cabinetry interior designer and maker. We can't fault the project management and professionalism of our project in-conjunction with the other trades. 9 House ensured timelines were maintained and quality of workmanship. We now have 3 amazing usable spaces to enjoy in our home. We were really impressed with the care around our project and the great communication every step of the way - VIP experience." - Kirsty May
