From forest to finished house – part 3: the house factory

In 1960 Derome supplemented its sawmill business with building material sales. Today the company supplies construction materials and prefabricated building components as well as complete houses under the A-hus and Varbergshus brands. The A-hus brand covers prefabricated houses that can be picked straight from the catalogue, with the focus on design. In addition to sales in Sweden, these houses are also exported to the Netherlands, Belgium, Germany and Denmark.

The factory in which they are built is located at the very same site where the company was founded. Production is highly rationalised. A CAD system generates core data files with information for the production line, which uses the drawings to produce the houses. Every year, A-hus builds and sells 350 houses, that is to say about one a day. The Lindell family went to have a look at the house factory.

Jonathan got to apply insulation strips to a window. He managed it well …

…as did Nils.

When the time came to try the nail gun, Jonathan focused on looking as cool as possible …

…while Hannah went all-out for enthusiasm …

…but wasn’t quite ready for the recoil!

Hannah shows the nails used in the nail gun.

Hannah watches as a window receives its final insulation treatment. This is the last step before …

What is One Tonne Life?

Is it possible to live carbon neutral today?

Every Swede contributes to the greenhouse effect with six to eight tonnes of CO2 per year.

With energy-smart housing, electric cars and clean energy, we could go on living almost as usual. Couldn't we? What does it really take for a family to live carbon neutral?
