Hi, we’re the Dufty’s — the husband and wife team behind Dufty+Co Builders.

A family of four standing on a grassy field with trees in the background. The father is wearing a blue shirt and cap, the mother is wearing a black top and denim skirt, holding a toddler. Their other child stands close by. It's a sunny day.

Based in Rotorua and proudly family-owned and operated, Dufty+Co was born from a shared passion for quality and genuine, down-to-earth service here in NZ. With over 17 years of experience as a Licensed Building Practitioner, Dan leads every project with a hands-on approach, an eye for detail, and a deep understanding of the building process. Alice brings her background in event management and bookkeeping to the table, keeping everything running smoothly behind the scenes.

We started this journey in 2018, and since then, we've built more than homes — we’ve built lasting relationships with our clients across the Bay of Plenty and Waikato regions. Whether it’s a new build, a renovation, or a full residential development, we treat every project as if it were our own.

The “+Co” in Dufty+Co represents the incredible crew that stands beside us — skilled, reliable, and just as committed to delivering top-quality results. Together, we pride ourselves on clear communication, honest advice, and a team culture built on trust, respect, and hard work.

We’re passionate about what we do and truly care about the people we work with. If you’re looking for a builder who brings heart, experience, and integrity to every job, we’d love to hear from you.

Thanks for stopping by — we look forward to building something great with you.

the building process.

we collaborate. we build. we deliver.

It all begins with an idea. We work in close collaboration between you and your chosen architect to ensure we have a perfect understanding of your vision.
Don’t have an architect? No problem, we can also assist you in choosing a design partner to work with through our close industry contacts.
We also have pre-approved plans to work from to make the process as easy as possible for you.
Once you’re happy with your designs, we provide a comprehensive quote to ensure the project is within your scope and target budget.
We will go through the scope of works with you personally to ensure nothing is missed and no hidden costs.
When you are ready to start constructing your project, we offer a full project management service – from the very beginning to the end.
We will facilitate your design plans through council to approved building consent, manage all aspects of construction through to completion, and obtain Council Code of Compliance for you.
We want you to be able to relax and enjoy the process - communication is key.
From design collaboration to completed construction.
With our expert team of qualified and experienced builders, we ensure every project is built with precision and high-quality craftmanship to ensure the final handover is exactly what you dreamed of.
