Hi, I’m Tom Dennehy—owner of Dennehy Construction—and building has always been in my blood.

Growing up in Christchurch, I was that kid who was always on the tools. My dad was a builder, and some of my best memories are of weekends spent helping him with home renos or knocking together skate ramps in the backyard. That hands-on experience sparked a passion for construction that’s stuck with me ever since.

I kicked off my apprenticeship in Christchurch, soon after, heading to Wellington where my wife Belinda was completing her Nursing Degree. There I gained some solid commercial experience on busy central city sites, such as Wellington Hospital and the BNZ Centre, before heading back home following the 2011 Earthquakes, to Christchurch, to take part in rebuilding the homes of our fellow Cantabrians. I was lucky to learn from a top-notch builder who really shaped the way I work today: with care, precision, and a strong sense of pride in every job.

In 2020, I took the leap and started Dennehy Construction. I wanted to build more than just houses—I wanted to build trust, quality, and lasting relationships. That’s why I keep communication front and centre, with weekly check-ins and a commitment to being upfront and available throughout the whole process.

To me, building isn’t just about timber and nails—it’s about people. I’ve worked hard to create a team culture where integrity, craftsmanship, and clear communication are the norm. It’s something our clients notice, and it’s why many of them come back to work with us again.

James Mullins and the team at First National Progressive have been using Dennehy Construction for the past 5 years “from minor repairs to large scale renovations, their professionalism and attention to detail consistently exceed our expectations.”

Shane Gibson, a Christchurch-based land developer, engages Dennehy Construction for their fifth residential development partnership “ Tom is exceptionally skilled in all aspects of construction and maintains a high standard of workmanship. He also takes responsibility for overseeing the quality of work completed by other contractors, ensuring everything meets his meticulous standards. His excellent communication skills stand out—any issues that arise are addressed promptly and effectively.”

Outside of work, I’m a proud dad and husband. You’ll often find me mountain biking in the Port Hills with my kids, swinging a golf club, or soaking up the outdoors. These places remind me why I do what I do: to help families create spaces where their own stories can unfold.

If you’re planning a build in Christchurch and want a team that genuinely cares about the outcome, I’d love to chat. Let’s bring your vision to life—together.
