Why do people more frequently say a house is too small?
I have yet to be advised that a house is too big, even when it's a 2300 sq ft beast ( not counting basement and garage). That is twice what we need---twice the renovation cost, twice the heating and cooling, twice the maintenance, twice the work.
It's just us three, Vivienne will not suffer for having been raised in a modest house with only one bathroom. Yes, two would be more convenient. But it's not the end of the world. And we can always add one.
I'm not going to commit to buying a house in an area I find boring as hell just because it comes with an extra crapper.
The garage, however, is a different story. According to Paulie, and I am beginning to see his point, you can never have a too large garage.
