We don't really do verandas in Finland, we have terraces "Terassi“ which are usually at the back of a house whikst verandas are usually at the front.
In Britain, a veranda can be at the front, back, or side of a house. Verandas are made from wood. Sports stadiums have terraces that slope up from the playing field so all the spectators can see what is happening on the field. There are also terraces that are cut into the side of a hill because it is easier to grow crops on flat ground.
Yep, I'm British and Irish (but have lived in Finland for 16 years) so I'm aware the word Veranda has a wide scope. Yet in finland Terassi means a porch or decking front or back, it has nothing to do with the "terraces" as you mentioned.
Veranta or Veranda is an uncommon word in Finland
There are some. But yeah, it's common to have a 'kuisti' in the front and a 'terassi' in the back. Doesn't affect the translation though; the closest word for veranda is veranta. It could be translated as 'kuisti' as well, but I think 'porch' might be more accurate equivalent for that one. :)
