Six reasons

Why clients choose us

  • A completed Cogan waterfront home in cedar and dark cladding
    01Since 1990

    More than 36 years experience

    Craig has been building in Northland since 1990, and founded Cogan Custom Homes in 2007 — long enough that much of the work now comes from people we built for the first time decades ago.

    Personal service

    You deal directly with Craig and Simon from the first meeting to the last. Craig oversees the project, Simon runs the site day to day, and there is no management layer between you and either of them.

  • The showhome kitchen, with integrated joinery and stone benchtops
    03Buildertrend

    Transparent communication

    Schedules, photographs, selections and progress updates in real time. Whether you are five minutes away or overseas, you always know exactly where your project is up to.

  • Aerial view over the Northland coast where Cogan builds
    04No hidden surprises

    Detailed cost planning

    A full cost breakdown rather than a headline number, so you can see where the investment actually sits — and change your mind while changing it is still cheap.

    05Salt air and wind

    Local coastal knowledge

    Waterfront and coastal specialists. Salt air, exposure, ground conditions and drainage all change how a home should be built, and that knowledge only comes from having done it.

  • Dry-stacked schist detail against vertical cedar
    06In the detail

    Quality craftsmanship

    Attention to detail from concept through to completion. The parts of a house nobody photographs are the parts that decide how it performs in twenty years.

What we build

Six disciplines,
one standard.

New builds, waterfront work, recladding and renovations — handled by the same team, to the same standard, under one point of contact.

Custom homes

Custom homes designed around your lifestyle.

Bespoke homes throughout Northland, tailored to your lifestyle, your section and your budget — from your first ideas through to handing over the keys.

02

Architectural homes

Building to your architect’s design.

We work alongside your architect or designer — we do not design the house ourselves. Bring us a fully developed set of plans, or an idea you are still shaping. The earlier we are involved, the more useful we can be about what a detail will cost to build.

Marsden Cove & waterfront

Building exceptional homes beside the water.

A waterfront home should do more than capture the view. Over more than 36 years we have built a practical understanding of Marsden Cove and the Northland coast — salt air, wind exposure, foundations, orientation and outlook.

Renovations

Transforming homes with confidence.

Renovating is often harder than building new. Every existing home has its own character and its own hidden surprises, and success comes from planning, experience and honest decisions made before construction begins.

Recladding

Protecting your investment for decades to come.

A well-planned reclad improves weathertightness and can significantly enhance your home’s value, durability and street appeal. It is also one of the most technically demanding forms of residential construction.

Plans and inspiration to help start your building journey.

Twenty-eight ready-to-build plans from 80m² to 266m², with indicative starting prices. A useful place to begin — and a plan does not have to be the finished answer.

What Cogan clients say

It is often said that building is as stressful as divorce — not with Craig! Project on time and on budget with every change or decision recorded on-line. In fact I never checked on our house at all during the build, just turned up when it was finished! Totally recommend.

Client review · 8 years ago

The Builders completed the repair Job on the house on time and did a great Job, it looks like new again. They went out of their way to be helpful and we would definitely use them again.

Client review · 3 weeks ago

Craig Cogan and his team made building our new house a very pleasant and worry free process. We are delighted with the result and very happy that we were able to obtain his expertise.

Building relationships that last

After more than 36 years in the building industry, one thing hasn’t changed — our passion for helping people create homes they’ll love for generations.

Every project is different. Every family is different. That’s why we take the time to understand not only what you want to build, but how you want to live.

Whether it’s a luxury waterfront home, an architectural masterpiece or transforming an existing home, we believe the best results come from strong relationships, open communication and genuine pride in our work.

Much of our work comes from repeat clients and referrals, which we believe reflects the trust we’ve built over many years.

Building your home isn’t simply another project to us. It’s a responsibility we’re privileged to be trusted with.

Questions people ask first

Can you price from concept plans?
Yes. Concept plans rarely hold enough detail for a fixed price, but we can prepare a realistic budget estimate from what is available. That lets you and your designer make informed decisions before investing in completed working drawings — and avoids expensive redesigns later.
Do you build new homes?
Yes — architecturally designed custom homes are our specialty. We work throughout Northland, creating homes tailored to their site, lifestyle and budget, whether that's a waterfront home, a rural retreat or a family residence.
Can you help with house plans?
Yes. If you have plans, we will price them and advise on construction. If you are starting from scratch, we can introduce you to architects and designers we have worked with successfully, and assist throughout so the project stays aligned with your budget.
How long does it take to build a new home?
Every project differs. Once consent is issued and construction begins, most custom homes take approximately 8–12 months depending on size, complexity and weather. You get a detailed construction programme before work starts.

Let’s build something exceptional together
