Gary Mason Construction

Let's build something exceptional

Specialists in complex and high design builds

Gary Mason Construction is a Christchurch based and owned construction company. We bring proven experience in architecturally designed homes and renovations, heritage restorations, commercial fitouts, and hillside builds that demand more.

For over 25 years, we’ve delivered flawless builds on steep sites, heritage properties, and intricate designs – projects where there’s no room for error.

At Gary Mason Construction, we believe that building is more than construction, it’s collaboration. A high-stakes build is more than getting from A to B. It’s a full team effort that brings together the client, architect, engineers, council, and subcontractors—all working toward the same goal.

When you work with us, you’ll get transparency, technical precision, and project leadership that keeps your vision intact without spiralling timelines or surprise costs.

About Us

Ready to build something others said couldn’t be done?

You’re not here for basic. Neither are we.

Most of our work comes through word of mouth. Why? Because clients, architects, and engineers know we deliver. In this business, reputation is everything and we guard ours by doing the job right.

Whether it’s a heritage commercial restoration, a complex hillside home, or an architect who loves pushing the envelope, we thrive where others hesitate.

With us, you get a partner who’ll manage your build with total clarity, and get the job done properly—no shortcuts, no dramas!

Whenever an obstacle looked like it would stall the build, GMC found a way to carry on

“Very personable, professional with careful attention to detail especially around listening and delivering to client feedback and needs were the main attributes that delivered a high-quality outcome on a complex and intricate job.”

“Impulse Imports was a very challenging project. It was a Historic Building in Christchurch that was damaged in the earthquakes. Gary was pragmatic, efficient and focused on meeting the budget and achieving a high-quality finish. I highly recommend using Gary for your next project.”

“Gary Mason and team rebuilt our 1880’s Norwich Quay building following significant Earthquake damage. This was a project requiring close communication with the owners, courage through the demolition phase and careful construction around historic features. The work was completed to a high standard and trust and relationships continued through some trying plan changes and compliance issues.”

“Gary Mason Construction has been wonderful to work with throughout the project. The sense of honesty and dedication to the project was evident... If I ever build another house, Gary and his team would be the builders for me. I will continue to recommend them to friends building new homes.”
