I think Finne Architects above summed it up - warm and natural. I have relatives in Finland and their calm exteriors often hide genuine natural warmth and the most welcoming homes you can imagine. They also have a real love of Nature and natural things in the home reflect this. Most Finns and Swedes strive to get to a summer cottage by a lakeside or sea during the summer months, so they can live uncomplicated lives and discover whats important again, far from the clutter and chaos of city life.

Which century?

Overwhelming
