The aim of the project for the area of the heart is based on the scheme of H-shaped circula-tions, which allows the arrival of natural light in all spaces and at the same time allows us to focus control to optimize the routes and the functionality of all areas. As there are three different areas, the connection between them and the clarity of traffic has been sought. To be able to work independently but communicated at the same time. Architecture aims to focus on the person, responding to their needs. We have evidence that the built environment directly affects our psyche. In this project, within the set of studies we have focused on the arrival of natural light in all the rooms, including those that remain in the centre of the area. This solution also allows us to open to the outside world and promote biophilia, helping patients recover faster. Following the same dialogue, through colours and different textures, the aim is to humanize the space and make the rooms suitable for the users and to promote that they feel welcomed by the spaces, with warm, welcoming, and positive spaces.
