Setting the foundations before going upwards

After having prepared the platform, the time has reached to start preparing the foundations of the house.

Due to the steepness of the slope part of the platform is based on solid ground but another part is just filling (you can see it in the pictures). The big holes that you see at the western limit of the platform have been filled with concrete and rocks in order to create a kind of posts that will hold the entire platform perfectly... and so that the house doesn´t end down in the valley ;-)
