The legacy of a building can be defined and successfully argued for in many different ways.  The initial concept is important.  The design process is important.  The execution is important.  But much of what building’s legacy ends up being could simply be defined as the experiences and stories that are told by the users and visitors.  Each individual that walks through any piece of architecture, globally know or not, will without a doubt perceive and feel something different and will then in turn go on to tell the story of their experience.  There is not right or wrong here.  And even if not what the architect intended, these stories over time help to shape the final (and longest) chapter of building’s legacy.
