The space between houses is smaller, and the houses have much smaller garages. However the house themselves are similar size.
> the houses have much smaller garages
Yes, this is what I mean when I say few Europeans have the two- or three-car garages needed for a table saw to be practical.
They really aren't. My house is a 1250 sq ft 4 bedroom house. It gets comments from friends and family for being relatively large for a 4 br here, since the norm is 1000 sq ft for a 4 bedroom. Similar style houses in the US seem to be about 2000 sq ft from a property search.
