The building "Detached House #373434775" is set with the tag "building=detached" but it is a shed or the extension of the garage of the house number 9.

I'd say it is better to change the building tag of 373434775 from "detached" to "shed" because I am not sure if it is really merged with the house number 9.
I will take some photos next time I go for a walk.
