We do not know because its not going to be a massive import an will
depend on the decision that the local mappers that will work on their
respective areas. However, we estimate that:

- For every house more or less it would be a parcel. In big cities
lots of houses have the same geometry as the parcel; in this case only
one geometry is created. Son It will be less than double the number of
ways.
- We guess that the 3D information will add more or less 3 times the
usual number of ways in a only houses import.

We have discussed that in the Spanish list and the consensus was that
it is better to put that information in the parcel because:

- If there is more than one build, yo what build will you put the
address information? Will you duplicate the info?
- If the parcel is big and the build is located far from a road (like,
for example, in rural areas) we think that it would be easier to the
routing service to find the entrance=yes of the parcel than to guess
hot to reach to the building.

We think that this way is the most useful way of doing, but if you can
provide us a better solution we happily change the import program and
the suggested import wiki.
