A crispy winter day in a certified Passive House

A crispy winter day in a certified Passive House

Posted on by Team Wunderbar
Another crispy morning with 2.6°C outside, but a cosy 19.2°C inside with zero heating in our certified Passive House.
Every winter we hear, “Yeah, but does that actually work?” The answer is yes and our power bill is happy to back us up.
Some people need to see it to believe it. Others need to feel it. Fortunately, you can do both.
If you’re thinking about building, this is the ultimate standard. And if you need one final nudge, you can even book an overnight stay and experience it for yourself.
At the moment, there are only two certified Passive Houses in New Zealand offering that opportunity, so it’s a pretty exclusive way to test-drive the future is now of home comfort. 🏡 ❄️😎

German‑Kiwi Houseiversary Edition

Two‑year houseiversary and our backyard has finally stopped looking like a post‑apocalyptic construction zone. After hauling 1500 STO buckets (yes, we counted… we’re German), and walking 30km from the front to the back because heavy machinery took one look at our driveway and said, “Yeah nah,” we somehow survived.

Thanks to our legendary construction nightmare, we ended up reverse‑engineering half the project like two stubborn Bavarian engineers trapped in a Kiwi DIY show. Armed with nothing but hands, shovels, determination, and the kind of passion that makes neighbours question your sanity, we transformed chaos into our own little magic backyard.

And because we’re German enough to love precision and Kiwi enough to give anything a go… we even built a tiny tennis court.

Not quite Wimbledon — but definitely “Wunderbar‑don.”

📣We made the front page of New Zealand’s largest newspaper, the nzherald.co.nz, in late March – highlighting our construction nightmare.🙌
 
Industry experts have since described our case as a textbook example of a system failing ordinary families. While our situation is unique in its details, it is sadly not unique in its outcome. Following the article, more affected families and tradespeople have reached out, sharing similar experiences.
 
We sincerely hope the builder’s bankruptcy is extended until the outstanding debts are repaid. This could be the crucial gap that prevents us from losing our new home to the bank — something no family should ever face‼️
 
More importantly, we hope this sparks a broader conversation and finally drives long-overdue reforms to insolvency and bankruptcy laws. Reforms that have been discussed and lobbied for decades. The construction industry is a major pillar of New Zealand’s economy. Allowing bad actors to walk away without meaningful consequences is not the Kiwi way. It encourages reckless and unethical behavior, leaving families and hardworking tradespeople to carry the burden.
 
This is not just about one family. This is about fairness, accountability, and protecting everyday New Zealanders 💟.
 
Please don’t turn a blind eye to families who are bleeding out while the system stands still. Speak up 💯 and share your story to Ben (NZ Herald) for more voices to be heard.

We are thrilled 😁 as we are the 2nd overall and the 1st ICF residential certified Passive House in the country that offers a guest room for you to book and stay overnight.
 
Recently, my parents stayed with us and were absolutely amazed by the comfort and performance of our home. Their feedback has been incredibly positive, and it’s wonderful to see how much they enjoyed their stay. Additionally, we already have reservations lined up through February and into March, which is a testament to the growing interest in Passive House principles.
 
If you or someone you know is considering buying or building a Passive House, our home’s performance will speak for itself. We welcome anyone to book a stay and experience the benefits firsthand. This is a fantastic opportunity for architects, builders, component suppliers, and others in New Zealand to recommend our home to potential clients. Staying in our guest room allows them to truly appreciate what a genuine healthy home feels like.
 
Housing is more than just shelter; it is a fundamental aspect of well-being and dignity, an international human right. Our home embodies this principle, offering a healthy and comfortable living environment.
 
We look forward to welcoming you or your contacts to our home in Orewa. 😀
Our unique designed and not overheated attic space

Our unique designed and not overheated attic space

Posted on by Team Wunderbar
My two boys absolutely adore our unique designed and not overheated attic space in our certified passive house.
 
Our focus has always been to design a home that is practical, with well-thought-out storage areas, and a place where my kids can have fun and unleash their creativity in a safe and enjoyable environment.
 
A big thank you goes out to Natural Paint Co and Harrisons NZ for your exceptional support and excellent customer service in helping us finalize this special space.
 
This year has been quite a journey for us, marked by some significant challenges. We’ve navigated a recent cancer journey, faced a total justice failure from the MBIE’s insolvency lead team, and endured nearly three years of ongoing and costly remedial works at an apartment complex where we own a unit. Despite these hurdles, we remain hopeful and continue to work diligently towards securing our newly built certified passive house.
 
As we look forward to 2026, we aim to close out some of these uncertainties and move towards a brighter future. We wish you all a wonderful festive season, filled with peace, joy, and hope for a better year ahead.
 
Warmest regards
Wunderbar Passive House Team ❤️
7 Homestar (v5 Built rating) received

7 Homestar (v5 Built rating) received

Posted on by Team Wunderbar
It’s been a little quiet around here with updates about our certified Passive House due to a cancer event in my family. We have been fighting through this latest challenge with the same determination we applied to our house journey.
We are thrilled to share that we have received our New Zealand Green Building Council – NZGBC Homestar certification v5 Built rating)! We aimed for an 8-star rating and got close, but missed it by a narrow margin. As we ran out of funds, we had to downgrade some items, sadly. The difference could have been fixed by improving other fixtures, but it was too late in the process for us. Additionally, we missed out on some Waste Management points, which were crucial for achieving the 8-star rating. Engaging multiple builders on-site and focusing on surviving and completing the house contributed to this oversight.
Looking ahead, we would achieve a higher Homestar rating in the future, like replacing downgraded items with more efficient ones. Once public transport is available in our new development (expected by 2027, according to Auckland Transport) and we have our solar system installed, we would be in a better position to improve our rating.
Despite these challenges, our lovely abode has scored top points for thermal efficiency and performance. This achievement is confirmed by both Passive House and Homestar certifications, and we are incredibly proud of it.
Thank you, Ammy and Kyle from www.se.org.nz being on our journey since 2021. Thank you, Andrew Eagles for your aid.

As of now, we are the 2nd out of 160+ certified passive houses in New Zealand that offer a guest room for you to book and stay overnight.
 
 
Anyone can book, and of course to all the architects, builders, component suppliers, and others in New Zealand, you now can tell your potential clients to stay at ours here in Orewa in case they need a little help making their final decision. To have a genuine healthy home is an international human right, which emphasises that housing is more than just shelter; it’s a fundamental aspect of well-being and dignity.
 
 
You may see the cost to stay as a help to ease our difficult financial position from the unexpected and challenging house build journey we experienced. We are more than happy to share our journey over a glass of beverage but with a focus on the benefits of a passive house. 😉

1 year houseiversary!

Posted on by Team Wunderbar

We moved in without functional bathrooms, running water, or flooring. Dust sheets covered the concrete and beach mats brought by our friends were used to create a small walkway for our kids. I showered outside with a garden hose in the middle of New Zealand winter. Now, one year later, we are proud of what we’ve accomplished. It is a house that needs little or no heating/cooling. It’s an incredible experience and soon you will be able to experience it too, as our guest room is nearly ready for bookings. 😊
