This is one of the reason that Spaniards dont bother with the paper work. Despite of a laid back life style every Spaniard is rushing some where. Further they are not blessed with patience.
As a result they dont wait for the councils incompetancy and on top of this to pay for petty little works etc. They dont just bother.
I have a Spanish friend of mine who bought a typical andalucian house with land, built a pool and an extension, his sister came to visit him and decided to build a mexican house on two floors, another brother came from Califorina built an cube style house, another brother decided to build a guest house a mexican cabana style.
There are four houses there, 3 swimming pool, all illegal, water & electrcity is supplied from the first house. A boundry wall is built around and large gate has been installed as well.
My friend and his family must have spent €6 to €7,000,000. they dont even entertain the thought that these properties could be demolished.
A classic case of Pasa nada
