High-End Extensions Throughout Nelson & Beyond
We specialise in high-end residential extensions for clients seeking long-term value rather than quick fixes. Many of our projects are located outside central Nelson, including Tasman Bay and the Marlborough Sounds, where quality craftsmanship and experience with complex builds matter.
Clients may bring their own architectural plans, or we can recommend architects and designers suited to the scale and ambition of the project. Throughout the build, you’ll deal directly with the owner-operator - ensuring clear communication, accountability, and hands-on oversight.
