The alarm came at nine o'clock on Wednesday evening.
- We do not yet know if anyone was in the house, says Kristina Hallin, spokesperson for the Bergslagen police region.
Police and ambulances are in place and the country road next to it is off.
- We have large vehicles and have to take water so the road is closed. It will probably take a while, says Robin Eriksson.
What may have caused the fire is unclear.
