Unable to answer "What’s the house number of this building?" – Retail Building – https://osm.org/way/184290238 via StreetComplete 60.0:

This building is suites 101-103 of this shopping center. The BWW is listed as suite 103 on their website but I didn't see any markings on the building to confirm that.
