Leeneia, timber-framed houses will also float, providing that they have lightweight cladding and roofs. I've seen newsreel footage of them being carried downstream in the floods, with the occupants waving from holes they've made in the shingles..... Landslides pushed them off the foundations.

Waving for help, not with glee, naturally.
Impressive big houses, too.

They do, however, burn very thoroughly. As the racing fraternity say, it is 'horses for courses.'
