The no wall house describes a place, formed as a conventional household including all the electrical equipment and some elementary facilities of a house, while it is connected to an autonomous sun power station and the internet and left basically roofless. This work is proposed to be installed in adequate landscapes in this accelerating global warming planet condition, together with desalination units that form the water sources of tomorrow. The water depends to power units that desalinates it and power depends to sun. Reverse osmosis systems will be crucial for this treatment too. The work also can be read as a comment to Archizoom or of Superstudio, revisited today.
