Waternet is the first Water Managment and Sewage Service company in  the Netherlands.  Herman Hertzberger got the chance to be the lead architect in designing its headquarters in 2005.  The building is a double tower that stands at the bend of a river in Amstel, Amsterdam. There are a number of air bridges that connect both the buildings, so it is very easy to get from one to the other.  The 8th and 9th floors share a bridge that is really the central main part of the building.  Here there is a long hall with a cafe in the middle.  This is where one can find the best views in the whole building.  Each floor has two areas.  One that is straight-sided and consisted of office rooms.  It looks like you typical office building.  The other area is curved where you would see more unique meeting areas, and places for guests to wait before being taken to an office.  This is one of Hertzberger’s most recent design, and you can see the modern influences in the building’s design.
