DURABILITAT
Even when we think we build a house is forever, experience is that the trends, regulations, social status, wars, economic prosperity, market opportunities to build more land, expanding parks, new public facilities or new roads, among many other things, make the house disappear before the materials are destroyed. There are houses over a thousand years, over one hundred years, there are houses of all ages.
What makes it more durable the house is the proper maintenance of its structure according to the maintenance book.
