Creating Sustainable
Solutions
Lightweight structural design, interior engineering, and sustainability consulting to minimise our carbon footprint in construction.
Solutions for Every Project
Design of
Architectural Elements
We specialise in the lightweight structural design of architectural elements in line with local codes and engineering best practices. Our scope includes ceilings, walls, bulkheads, glazing systems, façade structures, and more - tailored to ensure constructability, durability, and compliance.
Design of
Building Service Restraint
We design seismic restraints for building services such as ducts, pipes, cable trays, and mechanical or electrical components. Our designs meet applicable seismic codes and support both new and retrofit projects across New Zealand and Australia.
Engineering Compliance
We provide engineering documentation required for building consent and certification across New Zealand and Australia. This includes PS1 Producer Statements (NZ), Form 15 Design Compliance Certificates (QLD), Section 238 documentation (VIC), and Certificates of Building Design for other states.
Site Inspections
We conduct site inspections aligned with your project’s monitoring needs and issue PS4 Producer Statements where required to verify construction compliance. We offer both on-site and virtual inspections.
We provide lightweight structural engineering services across a wide range of project types and requirements. With a focus on interior and architectural design, we ensure each solution is efficient, practical, and tailored to your needs. Our team understands the varying compliance demands across Australia and New Zealand, and we’re equipped to support projects through all stages — from concept to completion.

Innovation & Automation
At Inside Collab, we’re always looking for ways to improve design outcomes and avoid project delays. That’s why we work with Moddle – a new software tool that automates the repetitive tasks and calculations that come with design. By integrating Moddle into our workflow, we’re able to deliver faster, more detailed outputs and explore multiple design options to find the most efficient solution — reducing both material use and embodied carbon in the process.
​
Moddle has recently launched to the public, so others in the industry can now benefit from the same time-saving capabilities we rely on.
