At the core of this exemplary passive solar design are green concepts and family values.
Vertiginous hills and mad access issues don’t usually faze Wellingtonians — but this site was a tad different. When Amélie Goldberg and Karl Wakelin came to investigate building on this 700m2 section in Wadestown, it had been on the market for 25 years. “At one stage, kids from the neighbourhood made a skateboard ramp here,” says Karl. But it was close to where Amélie’s parents live, north-facing and within their budget, so when Karl’s builder father, Max, gave the land the expert nod, it was all on.
Amélie, who’s a policy advisor on energy efficiency and climate change, and Karl, a building performance manager, saw this as an opportunity to explore green concepts in their own backyard. Karl had constructed a number of houses before, Max was a willing helper and, as the project went along, Amélie developed the hands-on skills to get stuck in too.
The first step was to clear the property of scrubby wattle. Karl spent many weekends cutting down brush, and four months and 100 wooden steps later, the build was finally able to begin.
Ben Mitchell-Anyon of Patchwork Architecture is a friend of Karl’s from university, and the two set about teaming the former’s design nous with the latter’s determination to make this a high-performing home. “I was focused on how it works for the humans inside it — its energy needs, comfort, durability and the way it dealt with ventilation and moisture,” says Karl.
Ben had his work cut out for him. He had to conceptualise a home that looked the part, was simple to build and was on track to achieve an 8 Homestar rating (a measure of efficiency and healthiness set by the New Zealand Green Building Council) — all for a budget of $450,000. It’s testament to a strong friendship that, three iterations later, the couple and their architect achieved a model they were all happy with.
The process, which featured on TV3’s Grand Designs, took 19 months in total. It’s easy to encapsulate that in a sentence — harder to live and breathe it. From dropping the digger in by helicopter to start it off, to the last day of the shoot, Karl was front and centre.
The double-storey 140m2 home that now sits along an east-west axis basks in the northerly sun. It’s clad in Abodo, a heat-treated pine grown and made in New Zealand that’s an eco-conscious alternative to cedar. Patchwork Architecture’s trademark galvanised pipe balustrades and mesh screens run along the verandahs that shade the living areas and bedrooms in summer. They’re a lightweight solution that lends a sense of playfulness.
Internally, the concrete floor on the lower level acts as a heat sink — a concept so well-considered the couple abandoned the idea of a fireplace. It’s the hidden extras that count, of course: the above-average insulation, and a mechanical ventilation system that breathes fresh, dry air into a home designed to be almost airtight.
The practicalities are matched by beauty. In the main living zone, the poured concrete buttress walls are standout features, laminated veneer beams slice through the space and the timber-clad walls have an eye-catching texture. “They’re a low-grade macrocarpa that was destined to make beehives,” says Karl. “We loved its knotty look and Ben had the great idea to get the wood grooved.”
The kitchen, too, is a focal point, and Amélie can claim much of the credit for its good looks — she sized up components then ordered flat-pack carcasses from Ikea in Europe. This white base was enhanced with plywood doors and shelving that she made herself in a woodworking class. A splashback pegboard painted green is a simple and stylish solution for hanging utensils.
Achieved for $480,000, this is a family home that’s warm, dry, comfortable and filled with heart. Karl and Amélie certainly learned a lot about green design — and about themselves. “I discovered how much mental capacity it takes to build your own house and juggle a job and a baby,” says Amélie. Karl was so exhausted by the time the Grand Designs director called time that he had to take several weeks off work.
The couple’s daughter, Claudie, may not realise she’s living in a supremely energy-efficient home but she has plenty of her own to expend. That includes clambering up the ground-floor balcony railings, swinging with a view of the Ngaio Gorge as a train clickety-clacks by, and donning her superhero cape as she dashes off on her own missions to save the world.
