Building projects that reward careful thinking

Diemarco delivers architectural new builds, residential renovations, and design-led commercial projects across the Queenstown Lakes region.

Our work is defined less by category and more by approach. We partner with clients and architects who value clarity, foresight, and thoughtful execution, guiding projects from early intent through to resolved, enduring outcomes.

What we deliver:

1/ Capability

We specialise in complex, design-led builds where detail, proportion, and execution matter. Our role is to translate creative vision into built form without compromise. To us this means respecting design intent while ensuring it can be delivered beautifully and practically.
2/ Return on Investment

A well-built space gives back over time. Through thoughtful planning and material decisions made early, we help clients invest wisely by creating homes and environments that inspire, nourish daily life, and support connection.
3/ Agility & Adaptability

Building will always involve decisions. Our job is to shoulder the weight of them. With clear expectations, strong systems, and agile problem-solving, we guide clients through the process with confidence and care reducing friction where possible.

Our build offerings:

Architectural New Builds

BUILDING GRAND DESIGNS
We specialise in new homes shaped by strong architectural ideas and a clear sense of intent.
From the outset, we work closely with clients and architects to ensure design vision can be delivered without compromise. By thinking carefully about buildability, sequencing, and materials early, we help translate ambitious concepts into built form with precision and restraint.
The result is a home that feels cohesive, considered, and deeply aligned with how it’s meant to be lived in.
Residential Renovations

TRANSFORMING SPACES
Renovation work requires clarity, sensitivity, and careful coordination.
We approach renovations with a strong focus on early planning - understanding what should be retained, what can be transformed, and how new elements integrate seamlessly with existing structures. Our role is to guide decisions that elevate everyday experience while respecting the character and potential of the space.
When done well, renovation doesn’t just improve a home, it changes how it feels to inhabit.
Commercial Build Projects

INSPIRED ENVIRONMENTS
We work with businesses seeking environments that support experience, function, and longevity.
Regardless of industry, our commercial projects are approached with the same level of care and foresight as our residential work. Clear communication, intelligent planning, and considered delivery ensure spaces are built to support the people who use them now, and into the future.

A collaborative building partner for visionary architects.

We work alongside architects and designers who value partnership and shared responsibility.

Our role is to protect the integrity of the design while navigating the practical realities of construction - communicating clearly, thinking ahead, and supporting outcomes that elevate the work of everyone involved.

We see collaboration not as a negotiation, but as a shared commitment to delivering something considered and well resolved.

"We met Joseph and immediately knew that he was the builder we wanted to carry out the work. Whilst we had ideas, Joseph had lots of practical suggestions that were useful and cost effective, and we were impressed by the workmanship and attention to detail applied to the job. Despite outside influences and material delays, Joseph worked around shortages effectively, and his relationship with other trades was very beneficial. We were extremely satisfied with the finished renovation and would have no hesitation in recommending Diemarco."

"Working with Diemarco was an absolute pleasure. Their clear communication, attention to detail, and proactive, solutions‑based approach made the entire process seamless. They produced a show suite that truly reflected our high‑end luxury offering, crafted with care and precision. I would happily work with them again and again."

—Alex Watts, Group creative lead at Winton
"The delivery of The Orangery required a builder who truly understood the nuances of the Ayrburn vision. The team at Diemarco delivered this project with a strong focus on communication and attention to detail on what was a complex build requiring significant coordination between multiple contractors.”
