No worries, I didn't look back to see it was building=building before.

skyscrapercenter.com is a database, which holds a vast collection of information about buildings, they consider this their proprietary data and while their terms mention "public use" after I asked them about use in OSM they clarified that commercial use of their data is not permitted. Since OpenStreetMap publishes data under the ODbL license which does allow commercial use, we can't use their data at all. That's why I removed those tags because it was all copied from that website.

What someone needs to do is go survey this building and measure the height and count the number of levels, and see what's there, is it offices, residences, then use that survey to re-add that information.
