So let's just say, hypothetically speaking, that the g.f. wanted to add
some square footage to her house. What are the considerations involved
in choosing between adding a second story, and cutting down on the
amount of lawn she needs to mow?

One factor we had disagreed about is the heating and cooling costs.
Seems to me that for a given total square footage, two story is better,
but she says she's heard otherwise.

I'm guessing there's no hard and fast rules, and surely personal
preference and lifestyle play a significant role, but what about
construction costs, maintenance issues, etc.?

I think aemeijers makes a good point when suggesting an architect or
designer look at the pro
blem. There is a lot more to adding on than the cost of roof or the
efficiency of a heating system. The final result has to meet a lot of
limits and solve a lot of problems - from capacity of existing heating
and power to legal limits to appearance to function.
