Specialist Network

For properties that require more than an agent.

The principle

Most property purchases are handled between two people, a buyer and an agent, with a solicitor brought in to handle the paperwork.
For straightforward homes on straightforward titles, that's the right amount of support, and it works well.

Some properties don't fit that model.

A coastal site with a complicated title, a renovation or rebuild ahead of it, and decisions that will compound over the next ten or twenty years isn't a transaction. It's the beginning of a project, and the agent who hands the buyer a contract and steps back at settlement has done a fraction of the job that property requires.
This page exists for the other fraction.

For me, with fewer campaigns running at any one time, there's room to do more than list a property and run a sale.
There's room to walk a buyer through the people they'll need to know, the order they'll need to know them in, and what good engagement with each of them looks like.
The reality of a property like this
The property currently being marketed in Oturu Bay, Tutukaka, is the kind of property this page was written for.
A title with some structural complexity. An existing dwelling that won't be the new owner's long-term home.
A site that requires careful consideration of council requirements, coastal regulation, surveying, design, and build.

None of these are obstacles, they're simply the nature of a property of this kind, and they're best approached with the right people in the right order from the start.


A buyer engaging with a property like this will, in most cases, need to work with at least four specialist disciplines before the property is fully theirs to live in or build on:
  • A planner to navigate the council and consent process
  • A surveyor to define the land and its boundaries with precision
  • An architect or designer to translate the site into a brief
  • A builder to bring the brief into reality
The order matters. The specialists matter. The relationships between them matter.
​

What follows is a curated list of professionals whose capabilities match the complexities around properties of this kind.
None of them pay for inclusion on this page. They're here because of the quality of their work.

The Planner

Heather Osborne: Commons Planning
p: 021 138 6128 | e: 
[email protected]

A planner is the first call after settlement, and often before settlement, on any property where the use of the land will be different from what currently exists. They translate the council's planning maps, the district plan, the resource consent requirements, and the coastal protection rules into a clear picture of what's possible on this site and how to get there.

A good planner saves money. A great planner saves time, money, and the buyer's relationship with the council for the duration of the project. Heather Osborne at Commons Planning has already been involved with the immediate Tutukaka area, including project work with the neighbours of the property currently in Oturu Bay. Her work in the area is grounded in coastal Northland's specific consent environment, and she understands how the regional and district plans interact on properties of this kind.

Her track record on the Northland coast speaks for itself. On a recent Tutukaka project delivered alongside Chapman Smith Architecture and RHJ Builders, an uncommon District Plan provision was identified during the consenting process, requiring an additional resource consent. Heather efficiently navigated the approval pathway and secured the consent within ten weeks of being engaged, including the three-week statutory Christmas and New Year shutdown period. 
Her ability to work collaboratively with the wider project team and achieve practical outcomes is representative of the service clients can expect.

​A full case study from that project is available at commonsplanning.co.nz.

The Surveyor

Simpson Shaw

@simpsonshaw.co.nz

Surveyors define what the buyer actually owns. On a property with title complexity: undivided shares, encumbrances, riparian rights: the survey is not a procedural step. It's a foundation document that every subsequent decision relies on.

The right surveyor produces a clear set of plans, a current and accurate boundary, and a working understanding of any title features that affect the use of the land. The wrong one produces a document that has to be redone when the architect arrives.

Simpson Shaw have already worked on this property. They played a key role in the preparation of the encumbrance that sits on the title, and they remain the most familiar professional party with how the title and the land relate to one another. For a new owner, this is the kind of continuity that turns a complex title into a manageable one. Simpson Shaw can pick up the work from where it was last left, rather than the new owner's team starting from a cold review.

For any buyer engaging with this property, Simpson Shaw should be the first surveying conversation.

The Architects:
​

Chapman Smith Architecture
p: 021 023 45821 | e: toby
@chapmansmith.co.nz
​
Toby Chapman-Smith leads Chapman Smith Architecture with a rare combination of design excellence and real-world construction experience. Holding a Master of Architecture with Honours, a carpentry qualification, and licences in both building design and construction, Toby brings a perspective that spans the entire building process from initial concept through to completion on site.

Having both designed and built homes himself, he is known for creating thoughtful, site-responsive architecture that balances design excellence, buildability and long-term value.

His work is grounded in a strong response to site, climate and landscape, drawing on natural materials and timeless forms to create homes that feel connected to their surroundings. His own Black Ridge House received Rural Home of the Year in 2022 and reflects the design philosophy that underpins the practice today.

Based in Northland, Chapman Smith Architecture specialises in residential architecture, delivering coastal, rural and urban homes, renovations and additions throughout the region, while also undertaking selected light commercial projects. The practice works closely with planners, engineers and consultants to guide projects from initial concept through to consent and construction.
​

Chapman Smith is the right call for a buyer who wants an architect who understands what's buildable as much as what's beautiful, and for a project where the construction side of the conversation matters from the first sketch.

Harrison Ryan Architects
p: 021 243 3366 | e: kris@hra.nz

Whangarei-based, Harrison Ryan is a Northland practice led by Kris Ryan. The firm works across both residential and commercial architecture, and their positioning is straightforward: context-driven, sustainable spaces designed specifically for Northland's environment.

That cross-disciplinary reach matters more than it might first appear. A practice that also designs commercial buildings brings a different kind of discipline to a residential project, particularly on a complicated site. There's a stronger orientation toward function, structure, regulatory navigation, and long-horizon thinking that comes from working with commercial clients, and it transfers usefully into a coastal residential build where the engineering, the durability, and the consent pathway all need careful handling.

Harrison Ryan is the right call for a buyer who wants a Northland-grounded practice with a strong contextual approach, and who values an architect who treats sustainability as a structural decision rather than a stylistic one.

Sumich Chaplin Architects
​
p: 021 721 411 | e: lawrence@sumichchaplin.com

Sumich Chaplin Architects is an Auckland-based practice with over 35 years in operation, led by directors Lawrence Sumich, Matt Chaplin, and Sam Baxter. They are a nationally recognised firm with multiple New Zealand Institute of Architects awards spanning regions from Auckland to Hawke's Bay to Southland, and a portfolio that includes Huka Lodge owner's residences, Matakauri Lodge work, and high-end coastal residential across the country and internationally.

Their own positioning describes their specialism as "coastal architecture attuned to sea and sky, embracing light, and the changing moods of the coast." For a property in Oturu Bay - where the position, the outlook, and the relationship between built form and water are the entire reason for the purchase, that orientation is rare and useful.
​

Sumich Chaplin is the right call for a buyer thinking at the scale this property warrants, who wants to bring a practice with the experience and recognition that match the position itself. For a property that will sit on this title for the next hundred years, engaging a practice with that depth of track record is a defensible decision long before the first drawing is made.

​
(Disclosure: Lawrence Sumich is a distant relative. The recommendation is based on the practice's body of work and standing in New Zealand architecture, not on some distant family connection, but the connection is worth noting openly rather than leaving unaddressed.)

The Builders:
​

RHJ Builders
p: 021 501 800 | e: richard
@rhj.co.nz

RHJ Builders, led by Richard Hilton-Jones, is a Whangarei-based practice with decades of experience and a team of ten qualified tradesmen and apprentices working exclusively in Northland coastal builds and renovations. Their portfolio includes some of the most considered architectural homes on the Tutukaka coast: Tawapou Retreat, The Wedge in Tutukaka, and the Bone House at Ngunguru.

RHJ are also the builder on the Tutukaka new build referenced earlier in this page. The Chapman Smith Architecture project that Heather Osborne at Commons Planning resolved the late-stage consent on. The triangle is complete: planner, architect, and builder who have already worked together on a Tutukaka coastal site. For a buyer engaging with a property in Oturu Bay, the value of that prior collaboration is not theoretical. These professionals know how to work with each other, and the project moves faster because of it.

RHJ are the right call for a buyer who wants a builder with both architectural experience and proven Tutukaka coastal track record, and who values a build process that begins with honest, transparent costing rather than the unpleasant surprises that less disciplined builders tend to produce.
​w: www.rhj.co.nz

Darcy Bowden Builders
p: 021 055 5900 | e: darcy@darcybowdenbuilders.co.nz
​
Darcy Bowden Builders is a Tutukaka-based family-owned practice with over a decade of experience and full New Zealand Certified Builders accreditation. The firm specialises in coastal new builds, renovations, and extensions, with most of their work concentrated in the Tutukaka and Matapouri coastal area.
​

Darcy himself grew up on the Tutukaka Coast, and that local grounding shapes how the practice operates: the firm is small enough that Darcy is personally involved in every project, and large enough that they take on serious architectural builds with confidence. NZCB certification matters more than buyers often realise. It confirms a builder is part of a regulated industry framework with formal complaints, dispute resolution, and quality assurance processes behind them. For a build of significant scale and budget, that protection is not optional.

Darcy Bowden Builders are the right call for a buyer who wants a smaller, deeply local practice with personal accountability from the principal, and who values a builder who lives within a short distance of the site they're working on.

Pete Brown Builders
p: 021 432 778 | e: petebrownbuilder@gmail.com
​
Pete Brown Builders is a Tutukaka Coast practice that works exclusively between Ngunguru, Wellingtons Bay, Tutukaka, Matapouri, Woolley Bay, and Sandy Bay. Pete grew up on the Tutukaka Coast and attended Ngunguru School, and the team is a tight-knit group of trade-qualified carpenters, a cabinet maker, a commercial contractor, and apprentices, all of whom live on the coast they build on.

There's a specific value in engaging a builder who genuinely lives on the site's coastline. The travel time is shorter, which means project oversight is more frequent. The understanding of the conditions: the wind, the salt, the way materials weather here versus elsewhere, is grounded in years of personal experience rather than coastal building textbooks. The relationship with local subtrades, council inspectors, and material suppliers is established and continuous.
​
Pete Brown Builders are the right call for a buyer who wants a deeply local team with a defined geographic radius, and who values the kind of quiet, ongoing presence that genuinely local builders bring to a project that other builders simply can't match.
​w: www.petebrownbuilders.co.nz

The order of engagement
For a property like the one currently in Oturu Bay, and for most properties of similar complexity, the order typically runs like this:
  1. Before settlement. Initial conversations with the planner and, if needed, a coastal consent specialist. Confirm what's possible on the site before the purchase is unconditional.
  2. Settlement to month three. Engage the surveyor. Walk the site with the planner. Begin early conversations with one or more architects.
  3. Months three to nine. Architect engaged. Brief developed. Initial design and consent work begins. Surveyor's plans inform the design.
  4. Months nine to eighteen. Resource consent and building consent processes. Builder engaged and tender or negotiation undertaken.
  5. Month eighteen onward. Build commences. Architect supervises. Buyer lives the project rather than runs it.
This is a rough map, not a fixed schedule. Every site is different. The point of the order isn't to follow it rigidly, it's to know what comes next, and to have a relationship with the person who handles it before they're needed.

How to use this page
If you're considering a property that requires this level of engagement, whether it's the Oturu Bay site, another listing in my care, or a property you're looking at elsewhere, this page exists to make the next step easier.

You don't need to engage all of these specialists. You don't need to engage any of them through me.
The professionals listed here work directly with their clients.


What I can do is shorten the time between "I'm thinking about this property" and "I know how to proceed with confidence".

If you'd like an introduction to any of the specialists named here, or a conversation about a property that might need them, get in touch.
