Also, did Tesla upgrade the 8 original posts to 250 kW or leave them at 150 kW? In the US they usually upgrade the old 120/125/150 kW posts when there is an expansion, but they often leave the 250 kW posts (V3) when they add 325 kW posts (V4). In the EU the V4 posts might only output 250 kW. Tesla does not document on their website if a station has a mixture, so it's up to websites like supercharge.info, nobil.no, and OSM to keep track of this. :)

Hi, I normally just map Superchargers in the US because that keeps me busy, but I noticed this one showed up as expanded on https://supercharge.info. I updated ref:supercharge_info because that should be a number (244), as in https://supercharge.info/map?siteID=244

Also, iD (OSM web-based editor) wanted to "upgrade" the station to a Tesla Destination Charger, so had to add not:brand:wikidata=Q478214 to prevent that.

By the way, what are the ref:tesla and ref:tesla2 tags used for? They are not present on any of the Tesla Superchargers mapped in the United States. Maybe they are old and not used anymore, especially the ref:tesla2?

3-storey is right across the street and 5-story is just to the south of Wasabi and the plaza. A 5-storey building there would be interesting.

It could be residential or office, and they could add on and build it higher. The buildings across the street and next door have retail (including restaurants) on the ground level and offices and apartments above. I could see a developer come in and turn that into a 3- to 5-storey building just like across the street.
