Who would have thought that this house concealed a 605 square metre underground mountain hall? Rumours about this mysterious house in Hardangerveien were revealed in 2004 when Hatteland Solutions purchased the house from the Armed Forces. Then it became known that the house had once been a hiding place for a top-secret defence centre that was built in 1958.
Hatteland Solutions has set up offices in the former detached house. The mountain hall will be a supplement to the computer centre in Vats and will eventually be able to offer customers one of Europe's most secure and modern computer centres.
