I'm documenting a historical past of this constructing (the tall half, though the small is hooked up and technically a part of the construction). The total partitions of home windows are attention-grabbing to me however I don't know the architectural terminology to explain this or different options of the constructing just like the arches under. Is that this a function of any sure sort of structure? The constructing was in-built 1973. Is there something notable about it in any respect architecturally?

For the record–this isn't homework or something like that–I'm a neighborhood historian helping native authorities free of charge with different parts of this historical past because the constructing is bought.
