Using a very small budget the idea was to revitalize an old apartment. Removing the excess of decoration and by using light and contemporary materials we converted an old and dark aspect into a new and cleaner look. We developed a house with two sectors, one social and versatile, and another one more personal and private. The main goal was to refresh the house by creating light, clean and minimal spaces. The materials selected were essential to obtain these goals. We applied singular materials, chosen due to their functional, esthetic and innovative qualities. Walls and floors were covered with micron-cement, a continuous material that gives spaces an industrialized look, but comfortable and clean at the same time. Walls that are not cemented were left simply white. The materials were applied in calculated points of the house. In the living room the fireplace was renovated and enhanced by being coated whit an innovative material, recycled wood and cement panels. In the main room, the wall of the bed headboard was covered whit OSB panels. This recycled material is made with the remaining portions of wood from the carpentries. In a new and modern concept and lifestyle, this material was chosen to this location, not only because of his aesthetic aspect, but also because of his characteristic as an ancestral natural material. By using different intensities, artificial illumination was also and essential aspect, both in circulation as in the more residual spaces. Although practical, the artificial lights were also used as a decoration element when for example it crowns the bed headboard of the main room. It were applied modern, future and innovative materials, in the search of a house that reflects contemporary lifestyle, that gives priority to social spaces without abandoning the more private e intimate areas.
