Nordströms museum is the heritage of Torsten Nordström. During his lifetime Torsten acquired a large variety of collectables that can be found in his museum. Due to a construction project in the neighborhood the foundation of Nordströms museum got disturbed. This led to the chimney of the building sinking, which gave rise to new problems for the construction. Today water is leaking through the plate roof and the building technology is outdated which has contributed to moisture damage in the attic. If nothing is to be done the collection is at risk to be destroyed.   Prior to this written report relevant literature has been studied and two inspections has been carried out. Because of insufficient documentation regarding the construction of the building assumptions had to be made.   With a curved roof full of cavities, rainwater is leaking through to underlying and sensitive parts of the building. The attic is without heating and its walls are missing vapor barriers and isolation. In combination all the above can cause major damage to the building.   This study has resulted in a list of suggested actions against the moisture problem of the roof and is meant to be used as a basis for future decision regarding an eventual renovation of Nordströms museum.
