The project develops from a landscape reading in accordance with an existing ruin in various scales and conditions. This element in bad conditions becomes the key element in the realization of this whole project. From the analogy of the house peeking over the river and the hills of the Douro, so arises the House DV_3, a demand for establishing continuities with the site. The House DV_3 follows the power lines of the surrounding and it is divided into three sections : a social area, an intimate zone and the a more private area of the house, dormitories. Presenting with a tectonic emergence in natural concrete, got hold through this mineral all the rocky appearance of the surroundings. This project is generated from the place and aspires to merge in it.
