If you don't look carefully, you might not even see the home that Jonathan Ridley-Jones and Shanon Ridd built at all! That!s because the house is a converted underground water tank.The only thing that can be seen from the surface is a door leading into the hillside."We've 25 never wanted to live in a ordinary house,"shanon says."Living below ground means that our home is quiet and very cosy-none of the usual draughts. It doesn't damage the local surroundings and has very low fuel bills. Some of our friends find it dark and feel shut in 3 when they first visit,but they soon get used to it!
