Put the House number field before the Street field
In some countries, House number needs to be before Street. Maybe this can be customisable by country? If not, I believe it's more logical to have House number first (smaller to larger).

I am not familiar with how the rest of the world works but I agree, I think it makes more sense to have the number before the street. I know that in the US, you never say the street name first.
