This PGB AC Citibank was made by Aras (AC) and originally was uploaded onto http://www.simcitypolska.pl/, which is no longer existing and this upload hasn't been available according to my best knowladge since then.  Please note with the permission of the Simtropolis Staff Members (Cyclone Boom and CorinaMarie), this file has been uploaded on behalf of Aras. It was not available anymore due to the unfortunate demise of the SC4 Polska site. All the works contained within this download (lots, descriptors and models) were created by Aras. Installation: Unzip the whole bundle, or COPY the "PGB" folder from the *.zip into your plugin folder. You don't need to keep the "Documents" folder in your Plugins.
To uninstall: bulldoze any instance of this lot in your city, then remove the file(s) from your Plugins.
Additional note: the original upload contained only an *.exe installer file, but since there is also a project of removing the *.exe installers and replacing them with a folder based drag-and-drop version, I used this method. The new upload doesn't contain the installer, but for archiving reason, I have it, and keep it safe. LIST OF ITEMS:
* 6x4 commercial office ploppable (only) building, which can be found under the Landmark menu. Dependencies: Porkie Props vol.1 Porkie Props vol.2 BSC Textures vol. 02 BSC Mega Props - SG vol. 01 **** The readme list this as a dependency, but after checking the files with SC4 Tool, you actually don't need this dependency for this upload. 
Have fun and enjoy! - STEX Custodian TEAM (Tyberius06, CorinaMarie, Cyclone Boom)
