SERVICES
What we build.
Premium residential construction across Warkworth, the Matakana Coast, and surrounding areas.
Every project we take on, whether it is a considered new build or a complex structural renovation, is managed with the same attention to detail, the same open book approach to pricing, and the same commitment to delivering exactly what we promise.
Below is an overview of what we do and how we do it.
Project Management
Building a home is one of the most significant investments you will make. Having the right person managing that process makes all the difference.
At RHM Construction, we take full ownership of your project from the first consultation through to code compliance sign-off. We coordinate every trade, manage the programme, handle council requirements, and maintain clear communication with you throughout, so you can stay focused on your life while we stay focused on your build.
Every project runs on our open book, cost plus margin contract. You receive a detailed estimate upfront and a weekly cost report with every invoice, giving you complete visibility of where your money is going at every stage.
What project management includes:
Full programme management and trade coordination. Council consent and code compliance management. Weekly progress reports and cost breakdowns. Regular client meetings and clear communication throughout. Single point of contact from start to finish.
New Builds
Building a new home from the ground up is a significant undertaking, and it deserves a builder with the experience, organisation, and care to do it properly.
RHM Construction manages new builds of all sizes across the Matakana Coast and Warkworth area, working closely with homeowners and their architects to deliver homes that are well-built, well-managed, and worth every dollar invested.
We have particular experience in high quality homes, projects that require precision, an understanding of design intent, and the craftsmanship to execute complex details to a high standard. If your project involves an architect or designer, we know how to work within that relationship to protect the integrity of the design.
Our approach to new builds:
Detailed upfront estimating using professional quantity surveying software. Open book, cost plus margin contract structure. Full project management including consents, trades, and programme. Regular client updates and transparent cost reporting throughout.
Structural Renovations
Structural renovations are where RHM Construction truly excels. Rob’s career began with complex structural work in Wellington’s inner suburbs, and that depth of experience shows in every project we take on.
Whether it is lifting a home, reconfiguring an existing footprint, opening up structural walls, or adding a second level, we approach every structural project with a level of care and technical understanding that the work demands.
This is not work to hand to a generalist. Structural renovations require precise planning, clear communication with engineers and council, and the kind of hands-on experience that only comes from having done it many times before.
Structural renovation work includes:
House lifts and foundation replacement. Second storey additions. Load bearing wall removal and reconfiguration. Structural strengthening and earthquake remediation. Complex whole-home renovations.
Additions and Extensions
A well-designed addition can transform how a home functions, adding space, light, and value without the cost or disruption of starting from scratch.
We manage additions and extensions of all scales, from a single room addition to a full ground floor extension. Every project is approached with the same standard of workmanship and the same commitment to minimising disruption to your daily life while the work is underway.
Working closely with your architect or designer, we ensure the new work integrates seamlessly with the existing structure, in both appearance and performance.
Addition and extension work includes:
Single and multi-room additions. Garage conversions and sleep-outs. Deck and outdoor living extensions. Full ground floor extensions. Second storey additions.
Building with the environment in mind.
At RHM Construction, how we build matters as much as what we build. We specify sustainable materials where possible, minimise waste on every site, and make considered choices at every stage of the process.
