Renovations

Additions and Extensions

House Builders Auckland

Expanding with Care, Building with Integrity

At Warwick Gair Builders, additions to existing homes are right in our wheelhouse. We love the challenge — and the reward — of expanding a home in a way that feels seamless, intentional, and enduring.

Whether you’re adding a new living area, a second storey, or a completely reconfigured layout, we approach every addition with the same care and attention to detail as a full new build. We take the time to understand your goals, your home’s existing character, and how best to tie the two together — structurally, visually, and practically.

House Builders Auckland

What We Offer

  • Ground floor extensions and room additions
  • Pop-top second-storey extensions
  • Full layout reconfigurations
  • Structural tie-ins and weatherproofing solutions
  • Coordination of design, council consents, and construction

With more than 40 years of experience, we understand the specific skill set required to execute an addition properly — knowing where to join old and new, how to maintain flow and proportion, and how to future-proof the work for years to come.

We collaborate with trusted architects, draughtsmen, and engineers, or can connect you with the right design professional if you’re just starting out. And when it comes to consents and council approvals, we’ll guide you through the process and handle the detail.

"From day one, Liam, the lead builder, impressed us with his excellent communication and professionalism. He kept us informed at every stage of the renovation, patiently answering all our questions and ensuring we were comfortable and confident with the process. His calm, approachable manner made the entire experience smooth and stress-free.

We couldn’t be happier with the outcome and would wholeheartedly recommend Warwick Gair Builders to anyone looking for a trustworthy, professional, and highly skilled team. Thanks again to Liam and the entire crew – you’ve created a space that we’ll enjoy for years to come!"

"The whole way through the project their continued contact, keeping us informed on progress, was magnificent and all the contractors on the job were also just as professional always showing up when appointments were made and completing the work to an excellent standard. I have absolutely no reservations in recommending them and we will definitely be contacting them again if needed. Thank you so much Alistair and Warwick for making our repair work stress free and we are now able to enjoy our place again!"
