The term DOME HOME is a combination of two crossword solutions, IGLOO (5 letters) and IGLU (4 letters). An igloo is a type of shelter made from blocks of snow, traditionally used by the Inuit people of the Arctic region. An iglu is a similar type of shelter made from blocks of ice, also used by the Inuit people. Both igloos and iglus are dome-shaped dwellings that provide protection from the cold climate.
