INGRID HJERTEFOLGER: When I look back at our creation now, I get a deep sense of gratitude
and joy. INGRID HJERTEFOLGER: We were inspired by the hundreds of natural buildings around the world.
It’s in our own and everybody else’s interest to protect, support and love the planet that
sustains us. COMM: As part of their quest for sustainable living, Benjamin and Ingrid built this incredible
glass dome house for £340,000 in the Arctic Circle. BENJAMIN HJERTEFOLGER: We started building the dome in 2012. We built for one and a half
years before we moved in. COMM: The huge dome is made of 360 individual glass panels and stands 7 and a half meters
high and 15 meters across. Designed to withstand winds of over 31mps, it can also take the
weight of the Arctic snowfall. BENJAMIN HJERTEFOLGER: It provides shelter from the Arctic climate and we need less energy
to heat the house. INGRID HJERTEFOLGER: We grow some of our own food and we collect wild herbs and plants
in nature. We don’t buy much stuff. BENJAMIN HJERTEFOLGER: It gives us a longer and warmer growing season. We have a water
treatment system where all the water we use circulates in tanks and this pumps out into
the green house, where plants and sand filter and clean the water and also takes nutrients
from it. COMM: At the centre of the dome is the family’s living quarters. INGRID HJERTEFOLGER: We wanted a house that made, is made of natural materials, that does
not pollute the air inside and has organic shapes, that is pleasant to live in. BENJAMIN HJERTEFOLGER: The inside of the house is made of cob, which is a mix of sand, clay
and straw. We also use timber. COMM: Both Benjamin and Ingrid were raised on the island and they’re now looking for
their four children to follow the same path. INGRID HJERTEFOLGER: Our three oldest children, they were very much a part of the building
process and they helped us build the walls of their own rooms. And they love the house
and they say that they never want to move, they want to grow old here with us. We want
to live sustainably and eco-friendly because the other alternative isn’t sustainable.
We worked so hard in the process of building it and it’s, it was well worth it.
