The verdict in three sentences
For a passive house and sustainable architecture practice in Auckland, the website has to prove performance with data (airtightness tests, heating demand, occupant feedback) and not just with handsome facades. An Auckland agency has the edge if you need photos, site videos and technical content produced locally, or a partner in the room at every meeting. If your data and imagery are ready, a remote studio delivers a clear, fast site free of greenwashing in 3 to 4 weeks, at a much lower total cost over three years.
Who does what in each scenario?
The real question for a passive practice is not whether the agency sits in Ponsonby or on the other side of the world, but who produces the technical material. An agency can write lovely copy; it cannot invent your n50 values or energy monitoring results. The table below splits the work realistically.
| Task | With an Auckland agency | With a remote studio (Kolonell) | What the practice must supply |
|---|---|---|---|
| Scoping workshops | 2 to 3 in-person workshops | 2 video calls of 60 minutes | Goals, audiences, 10 priority projects |
| Photos and site videos | Can be produced in-house | Local photographer you commission | Access to homes, owners' consent |
| Project pages with performance data | Written from your notes | Native English copy from your notes | Test results, floor areas, target standard |
| Explainer pages (passive, comfort, costs) | Often billed as extras | Included depending on plan | Technical review by a partner |
| Qualifying form (site, budget, timeline) | Yes | Yes | Question list and budget thresholds |
| Ownership of domain, code, images | Negotiable | Domain and hosting in your name, code handed over | Photo licence agreements |
| Time zone NZST/NZDT | Same | Project manager reachable in your hours | One available internal contact |
Mind the photo licences: many New Zealand architectural photographers grant a licence limited in time or use. Make sure it covers the web, awards and competitions, and press, with no expiry.
What does each scenario cost over three years?
The figures below are a 2026 ballpark drawn from public local agency rate pages and typical agency quotes in Auckland. New Zealand providers invoice in New Zealand dollars; Kolonell invoices in US dollars.
| Scenario | Auckland agency | Local freelancer | Kolonell |
|---|---|---|---|
| Lean: 8 projects, core pages | NZD 12,000 to 20,000 | NZD 5,000 to 9,000 | Starter, USD 2,900 |
| Standard: 20 projects, filters, technical blog | NZD 22,000 to 40,000 | NZD 9,000 to 16,000 | Growth, USD 4,900 |
| Ambitious: multilingual, resources, long case studies | NZD 40,000 to 70,000 | Rarely taken on | Premium, USD 8,900 |
| Annual maintenance | NZD 3,000 to 8,000 | NZD 1,200 to 3,000 | 3 months included, then on quote |
| Photography of one completed project | NZD 1,200 to 3,500 | NZD 1,200 to 3,500 | NZD 1,200 to 3,500, commissioned locally |
| Standard 3-year total excl. photography | NZD 31,000 to 64,000 | NZD 12,600 to 25,000 | Growth plus occasional support |
For a passive practice, Growth at USD 4,900 usually covers the essentials: filters by type (new build, retrofit, multi-unit), project pages with performance data and a technical blog. Premium at USD 8,900 makes sense if you publish long guides, detailed occupant feedback or a Mandarin or Korean version for part of your clientele. Everything is set out on the international website offer.
When is the local agency the better option?
An Auckland agency remains the better choice if you are starting from zero on imagery: coordinating three or four shoots in lived-in homes, with owners' consent, is easier with a team on the ground. It also wins if the website sits inside a wider plan with open home events, sustainable housing shows and press relations. And if your partners insist on in-person reviews, accept it rather than forcing a way of working that will slow down every sign-off.
A remote studio is enough when the practice has a regular photographer, an up-to-date project database and someone who can approve quickly. Useful questions for both providers:
- How do you present technical data without overloading pages (tables, tooltips, downloadable PDFs)?
- What mobile LCP score do you target with 40 photos per project, and in which format (AVIF, WebP)?
- Can the CMS add an airtightness result to an existing project page?
- Is form data hosted in New Zealand, Australia or elsewhere?
- How do we recover access and files if we switch provider?
Which New Zealand rules apply?
In New Zealand the title registered architect is protected under the Registered Architects Act 2005, and the register is kept by the NZRAB: the site should distinguish registered architects from designers and graduates. Environmental claims fall under the Fair Trading Act 1986, which prohibits misleading representations; "zero carbon" or "certified passive" must match a real, verifiable certification, project by project. The Privacy Act 2020 applies to every organisation collecting personal information, with no size threshold, so you need a privacy statement and controlled handling of form data. For accessibility, WCAG 2.2 AA is the sensible target. This is not legal advice.

Mini case study
Illustrative example: Hannah, co-founder of a 6-person passive house practice in Grey Lynn, is comparing a local agency at NZD 28,000 with NZD 400 a month for maintenance against Kolonell's Growth plan. She has photography for 12 projects and test results for 9.
Agency over three years: 28,000 + 36 × 400 = NZD 42,400. Kolonell Growth: USD 4,900, roughly NZD 8,300 depending on the rate, plus NZD 1,500 a year of changes after the 3 months of support, about NZD 12,800 in total. The gap of about NZD 29,600 would pay for more than eight shoots of completed projects. If a single qualified enquiry for an NZD 1.5 million home converts thanks to the technical pages, the resulting fees far exceed the investment. Hannah would choose the agency if she had no imagery at all.
FAQ
Should we publish airtightness test results?
Yes if the homeowner agrees: a measured n50 value builds more trust than a slogan. Allow 30 to 60 minutes to prepare each project page with its data.
Can a remote studio write about such technical topics?
It writes from your notes and reports, then a partner reviews. Plan 1 to 2 hours of review per explainer page.
How long until launch?
Plan on 3 to 4 weeks with Kolonell if content is ready, versus 8 to 14 weeks in general for an Auckland agency.
Is the time difference a problem?
Kolonell's project manager is reachable in your Auckland working hours, with a 30-minute weekly check-in, and 3 months of support are included after launch.
Can we add a Mandarin version?
Yes, the Premium plan at USD 8,900 covers a second language. To price your case, request a free quote.
Let's scope your project. A passive house practice site with performance pages and a technical blog typically scopes between USD 4,900 and 8,900, delivered in 3 to 4 weeks. See the international offer or request a free quote: detailed reply within 48 hours.
