Traditional Cave Houses.
As shown on the left, these are cave homes that are entirely underground with no additional rooms built onto the front. As these have massive walls they have superb thermal insulation and maintain a very nearly constant temperature of about 20 deg. C. summer and winter.
Because very few, if any, concrete blocks and other conventional building materials are used in the renovation of these cave houses they are more eco-friendly.
They have the disadvantage of fewer and smaller windows, so they can be a little dark inside in winter - no problem in summer.
Modern Cave Houses.
These have conventional build to the front of the cave house. The conventional house part often has poorer thermal insulation properties than the cave part and will therefore not maintain the even temperature, summer and winter. They have the advantages that they have more and larger windows than traditional caves and a more attractive external appearance.
