I think I see what they are doing... they have lots of small residence buildings scattered all over the Brooklyn heights area. Whey they are going to do is move the printing facilities to Patterson, move the related bethelites there and then sell all the buildings. They will still need a central residence complex to hold the remaining bethelites and they will all go in the new residence buildings.
Basically they are consolidating the labor force residence and selling off all the small buildings.
