Why Choose Us?
Exceptional Eye For Details
Certified Specialists
When you choose Substrait Construction, you’re choosing certified specialists who excel in everything from high-performance builds to high-end renovations, as well as villa / bungalow renovations and extensions. Fully licensed and trained, we handle the entire process council approvals, compliance, and all the details. With us, you’ll feel the difference of a team that makes any project seamless and genuinely enjoyable.
Quality Control
We follow a comprehensive quality checklist built from years of hands-on experience. Every stage is reviewed and signed off, ensuring nothing is missed and everything is completed to the highest standard the first time.
Clear Communication
We keep communication simple and consistent. You’ll receive clear updates at the right moments, so you always know where things stand without being overwhelmed. It’s a smooth, transparent process from first meeting to final handover.
Project Management
From concept to completion, we manage the entire build process. We help you connect with the right architects and help work through constructability decisions, pre-build planning, and QS costings. Once underway, we coordinate sub-trades, oversee timelines, and keep communication clear so your project runs smoothly and stays on track.
Transparent Pricing
From the first meeting through to a full project proposal, we manage the early-stage process so you have clarity before any work begins. After discussing your ideas on site, we arrange detailed concept plans and have them costed by an independent Quantity Surveyor to give you an accurate picture of the project.
QS costing is a paid service, but it provides a clear breakdown, realistic pricing, and fewer surprises later on. We then turn that information into a structured project proposal outlining the scope, timelines, and next steps—so you know exactly what to expect before committing to the build.
Building for a Better Tomorrow
At Substrait Construction, we weave energy-efficient principles into our high-end builds and renovations. As Passive House certified tradespeople, we draw on proven techniques and experience gained from working in the Queenstown region to apply sustainable solutions that suit your home and lifestyle. While we don’t claim to be full Passive House specialists, we bring a refined understanding of energy efficiency that helps create a greener, more comfortable home for tomorrow with the same craftsmanship we bring to all our jobs.
