Here is a description from the architects: The design takes advantage from the difference between the street level and the lower level of the plot, by positioning the living room in this lower level which ensures the required privacy and maintains the view of the distant landscape through the void. This simple home adopts simple constructive solutions, reducing the actions required for its achievement. The structure of the volume is resumed to masonry walls and reinforced concrete. Installations are apparent and performed without interference. After that the finishes are simple: monolithic concrete flooring and white Portuguese Stone. The walls without finishes are ready as it built. A single exception: the wall with books, finished with time and history. We find this home truly spectacular and educational from all points of view. But we just have to wonder how long it would take to clean it up from top to bottom.
