Our vision is to shape the future of commercial construction.

Collaborative. Courageous. Caring.

'Our Three Cs' embody the spirit and energy of Calder Group at its core.

A trusted team of experts.

Our in-house specialists can deliver the entire project from 3D detailing to installation while our quantity surveyors and project managers keep your project on time and on budget.

Our leadership team work collaboratively to ensure the successful planning, execution, and completion of the project, while adhering to budgetary, scheduling, quality, and safety requirements.

Family-owned for more than 40 years.

Founded by Stephen and Lynne Calder in Tapanui, West Otago in 1980, Calder Group remains a family-owned and run business.

Our reputation for providing expert advice and personal service has been built over many decades and it’s an important part of who we are today.

Together, we deliver.

Unlike other construction companies, our vertical integration from design to manufacturing and construction means we hold accountability for keeping the brief and budget together, managing risk throughout the entire project lifecycle.

Delivering solutions, The Calder Way.

Unlike traditional design build models, our vertical integration means we’re truly with you from concept to completion and beyond.

By embracing lean construction principles and practices, our project teams can optimise resources, enhance collaboration, and deliver projects that meet or exceed client expectations.
