The new building is situated next to the existing museum of agriculture and museum of technology. It doesn't require a new entrence situation but is accessed via the old museum. A bridge in the 1s floor connects all three buildings to get a new museum complex.

From there they can enter the old museum entrence hall in which they can buy tickets and find shops, restaurants and event-rooms. The exhibtion starts in the 1st floor.
The actual extension consists of a solid disk and the characteristic triangular showcase. The special shape of the building helps to give a strong identity and is meant as a new landmark. The shape whichdraws from the neighboring buildings and regulates the indoor climate in a natural way.
