Harbour Build is a renovation, extension and new home company owned and operated by the Monaghan family. For more than 35 years we have been renovating and building new homes across Brisbane and the Gold Coast, and our approach has never changed: quality over quantity. Every project is built to a high standard of workmanship that delivers lasting value and real satisfaction for the people who live in it.
After many years of renovating, extending and building across South-East Queensland, we've become known for a set of qualities we hold ourselves to on every job: quality, integrity, skill, knowledge and genuine care for the client and their home.

We believe a great build starts with trust between the builder and the client. We build because we care about the result, and our job is to turn your vision, ideas and needs into a finished product you're proud of. That means being trustworthy, knowing the best building techniques inside and out, and delivering exactly what was agreed, on time and to standard.
Whether it's a brand new home, a second-storey addition, an extension, an outdoor entertainment area or any other renovation, every project is built with the same extensive skill, quality workmanship and quality materials.
Harbour Build is run by Ken Monaghan, a licensed and highly qualified builder with decades of hands-on experience, working alongside the next generation of the family trade. Ken is personally involved in every project. That direct involvement keeps communication clear, tightens quality control, and means the person responsible for the result is the person on the tools and at the table.
We build for people like you: families and homeowners right across Brisbane and the Gold Coast. We're grateful to every client who has trusted us with their home, and we treat each project as the unique job it is, with the individual respect and attention it deserves.
We're problem-solvers first. Over the years Harbour Build has become known for taking on the projects other builders say no to, such as difficult sites, awkward extensions and complex renovations, and seeing them through with care and precision. That mix of deep experience and a genuine passion for finishing every job well is a big part of why clients keep coming back and keep referring us.

The core of everything we do, and the principles behind every home we build.
Quality isn't just what you can see. It's what's done behind the walls, under the floor and above the ceiling. We put the same care into every hidden detail as we do the finished surfaces, because that's what makes a home last.
Trust is built on the quality of the builder and an honest relationship with the client. Every cost is laid out clearly in the quote, with no surprises. A good working relationship and open communication are a big part of every successful project.
Commitment is working alongside you to find the best solution for your build, and holding the work to the same standard we'd accept in our own homes.
Integrity is the foundation of every good relationship. We listen, we communicate, and we see the project through to completion, finished on time and to the standard you expect. That's the integrity the whole team at Harbour Build stands behind.
