This holiday house was to be a base for its owners to explore the outdoors with their young family.
They wanted something minimal, industrial, and inspired by south island high country huts. They wanted good connection to the outdoors, plenty of storage and overflow sleeping space for family and friends, hard-wearing durable finishes, a big mud room for wet and muddy gear and a warm comfortable efficient space. The Hiberna team worked with national Passive House experts eHaus to design and build a simple energy efficient house that was hard wearing but none the less outstanding in its performance and appearance.

One of the main challenges was the wind. Both for the design and on site during construction 155kmh gusts one night in january: Thats a force 2 hurricane. The site is in one of the highest wind zones in NZ and we needed significant extra structure LVL to cope with the high wind load. The design does include some sheltered outside sitting space to the east as the wind comes mostly from the north-west.
We kept the Auckland clients up-to date with an app called Trello. We uploaded photos and gave regular updates so that they could follow the progress of the build from a distance.
We achieved an air change rate of 0.42 ACH – well below the Passive Housestandard of 0.6
The house passed an air tightness test using a blower door to make sure there are no leaks.
The final key is a heat recovery ventilation system that ensures fresh, dry air 24/7. We used the Passive House Planning Package (energy modelling software) which will ensures that the house will perform.
The client wanted a tall, compact barn-like building that stood out from the majority of houses around it.
The timber triple glazed windows were surplus to requirements on another project, and incorporated into the design.
The house is designed and detailed to be as close to zero energy as possible with the budget constraints. Internally the client wanted a vibrant, individual aesthetic which included green (living) walls in the shower, custom engineered staircase, built in hidden joinery and reclaimed items.
A tight budget and a desire for a warm, high quality home led to a constraint on size, with provision to extend in the future. The solid plasters, cedar cladding and hand crafted timber features give delight and character to the building, while the fully insulated slab and recessed thermally broken windows help to achieve a warm, energy efficient home that didn’t break the bank.

An oasis in the centre of London, this light and airy artist’s studio was a rebuild of an existing dilapidated structure. The challenge of the 25m tall protected London Plane tree growing 1m from the building was met by creating a curved wall around the tree.
The brief was to create a warm, bright and inspiring place for the client to work in. A harmonious space characterised by natural materials and hand-crafted elements.
“Working with Ben was an incredibly positive experience. Ben renovated and redesigned our summer house/artist studio during his stay in our neighbourhood in London”
“Without knowing the local suppliers, without his normal tool kit and his own car he did an amazing job. Not only did he do an incredible job incorporating all our (mad) wishes, he also never lost sight of the importance for longevity of the structure and the need for of minimising the buildings environmental footprint. Under very adverse conditions (ie a very rainy year),with bottomless creativity, patience, knowledge and passion he created a stunningly beautiful building which has given us pleasure every minute since.With immense gratitude I can only recommend wholehearted Ben and his team”.
