Unable to answer "What’s the house number of this building?" for https://osm.org/way/674622360 via StreetComplete 55.0:

This building is also number 25, this half has access to stairwells 3 and 4, the half to the south has access to stairwells 1 and 2. I'm not sure how to annotate this. I added a photo of both the north and south doors
