Technical architectural specialists for residential and commercial projects

Business Summary: Irvine Technical Consulting is an Auckland-based architectural consultancy specialising in technical documentation, architectural drafting, building consent and BIM management for residential and commercial projects across New Zealand.

Meet Jonathan Irvine, the architectural technician behind the practice

Jonathan Irvine has spent more than 15 years as an architectural technician, specialising in the technical side of architecture and building consent, and it is genuinely the part of the process he enjoys most.

Much of the industry gravitates towards front-end design, but Jonathan is drawn to the details: the junctions, the documentation, the coordination and the problem-solving that quietly determine whether a building performs well for the next 50 years or causes headaches from day one.

Jonathan is a Licensed Building Practitioner (LBP) in Design and a member of Architectural Designers New Zealand (ADNZ), and he runs Irvine Technical Consulting alongside his wife. It is a small, deliberately focused practice, and every project comes across his desk personally.
Clients value working directly with Jonathan because he makes complex technical issues easy to understand. Whether explaining a building consent requirement, identifying a design risk or coordinating consultants, his approach is practical, collaborative and focused on finding the right solution, not the most complicated one.

From technical specialist to consulting partner

Irvine Technical Consulting was founded on a straightforward idea: building science and regulation in New Zealand have become far more complex over the past 15 years, and not every architectural practice has the in-house capacity, or the specialist technical skill set, to handle consent documentation and coordination well.

Rather than trying to be another design-led practice, Jonathan built Irvine Technical Consulting around the technical expertise many projects need but not every practice has in-house.

Today, work comes to us in two ways. Sometimes clients approach us directly and we help them find the right architect, then guide the project through documentation and consent.

Other times, architectural practices bring us in as an outsourced technical arm, handling the building consent documentation and BIM coordination they do not have the capacity for internally.

Smart choices that support long-term durability

Good buildings don't happen by chance. They come from thoughtful design, smart technical decisions and careful coordination long before construction begins.
Durability is about far more than selection quality materials. It comes from designing every detail with care, avoiding complex junctions that are prone to leaks, and choosing robust solutions rather than simply meeting the minimum building code requirements.

Every project is modelled in 3D to an exceptional level of detail, allowing Jonathan to identify critical junctions and potential risk areas that are often difficult to detect using conventional 2D drawings.
This proactive approach helps resolve issues early, creating buildings that perform better, last longer, and require less maintenance over time.
