Renovations & Upgrades

A renovation is your chance to reimagine the home you already love.

Maybe your home is dated, too dark, or no longer suits your lifestyle. Maybe you need more space, better flow, or rooms that work harder for you. Whatever the goal, a renovation is your opportunity to reimagine your home and elevate it to its full potential.

At Marshall Builders, we take a thoughtful, detail-driven approach to renovations and extensions. We understand the complexity of working within existing structures, and we know how to balance practicality, design, and craftsmanship to achieve a seamless result — where old and new blend together effortlessly.

Whether you’re modernising a single space or reconfiguring your entire home, we work closely with you to create beautiful, functional outcomes that improve your everyday life.

“Finding the right builder wasn't easy. We had a small kitchen project compared to any other. But the Marshall Builders team made us feel that our project was as important to them as it was to us no matter the size. They are such a patient and caring team. We love our new kitchen. Marshall Builders offer top quality service. They are puntual, honest and super reliable. I am already thinking of our next project with them.”

★★★★★
As an Architect myself the design vision was clear in my head and on paper but needed the skill of a great builder make it reality and bring it in line with budgets - and this is where Steve and his team stepped in. Clear communication, right questions asked when required and upfront about costs and suggestions for savings. Highly recommend.

★★★★★
“Marshall Builders recently built a retaining wall for our property, and we couldn't be more pleased with their work! Despite coordinating the project from overseas at the time, Steve and the team made the entire process incredibly smooth and stress-free. The communication was fantastic— always friendly, prompt and clear. ”
- Lydia
★★★★★
“I rang Marshall Builders this morning after an unproductive internet search on how find a service provider to navigate a skylight problem (not installed by Marshall Builders). Steve has to be the kindest, most helpful builder in Nelson, patiently listening to my tale of woe & advising what to try next. If he can be this kind and helpful to a random caller, he’s definitely the right person for anyone wanting to build or renovate!”
- Pam
★★★★★
“All of the crew from Marshall Builders are incredibly professional, efficient, and helpful. They're always prompt and keep in constant communication with me. The crew work well together as a team. From a new skylight to a new home build they make sure your property is well protected and clean up after the work is completed.”
- Blair
★★★★★
“We used Marshall Builders for a pretty extensive renovation and roofing repairs. We are so happy with the job and can say that every person on their team is incredible at what they do. All of the sub contractors were organised through Marshall builders which really takes the stress out of everything and separates these guys from competition. Highly recommended!”
