How can you describe this building as filler?? It is one of the most eye-catching, distinctive, and memorable buildings in the entire city. Love it or hate it, it isn't filler.
16th tallest in the city, 17th to the roof. Boston has a strong supporting cast but is still lacking in the headliners. While SS stands out due to design and lighting, it's still dominated by 1 Financial next door.
"Filler" may not be a completely appropriate term, but from many angles this just isn't tall enough to stick out from the crowd. It does look great coming in from the South.
