>Terrace------Some people call them patios or balconies

>Terraced Houses?

Yes, a terrace is sometimes a paved area, like a patio. It also a way of terracing a slope to make level areas, like the rice terraces of South East Asia.

Terraced houses, especially in the North of England, are joined up houses, built in rows. If you see "Billy Elliot" or "Coronation Street" you will see them. I can't see a good photo of one on the internet. More modern examples tend to be called town houses.

A Georgian terrace, found somewhere like Bath or Leamigton Spa would be rather elegant: http://www.leamingtonspa-index.co.uk/tour/tour09.html
