Hi Marc,

A couple of things?

Some houses (depending upon country) don?t have numbers at all, only names.

Also, if you?re going to break it up into house name/number and street address, apartments/units/flats will also need to be called out separately.

Ordinarily, one either overloads ?street address? to contain all of the information more specific than street name, or one must specify all of the possible properties (accounting for all of the different address formats in the world, more or less). 

For example, this is how Royal Mail in the UK specifies addresses:
