Having been to the Tubman house for meetings I have to say that it was a poorly designed building inside...dark, gloomy, a warren of split levels, empty and wasted space, stairways, claustrophobic meeting spaces, and an undersized kitchen. You had to walk forever to find a rest room. It was a poor attempt at 70's 'avantgarde". Glad they're rebuilding and hopefully making the interior more useful for more people.
Yeah I didn't really understand the love of the building. I think it's probably more of who occupied it rather than the design of the building itself. The new building is definitely a much nicer and more sensible design.
I walk past this almost daily. The thing that continues to amaze me is size of the pit. There are some large buildings in the South End, for sure, but in general everything seems pretty human sized. The square footage of this plot is remarkable to see in person.
