El área de intervención del Plan Detalle comprende una superficie aproximada de 16 ha, con una población de 2288 personas, 1375 hogares y 1143 edificios residenciales (censo 2001).
Este plan tiene como objetivos:
• promover el desarrollo urbano Centro Histórico;
• promover el Centro Histórico como motor para el desarrollo de nuevas actividades y funciones;
• promover la apreciación de la especificidad y singularidad de Olhão, con el fin de mejorar la proyección de la imagen de la ciudad.
De este modo, el Plan propone las siguientes líneas de acción:
• salvaguardia de la morfología urbana y la escala propias del Centro Histórico;
• inventario del patrimonio arquitectónico;
• rehabilitación de edificios existentes;
• coordinación entre las distintas regulaciones locales aplicables;
• definición de medidas para la integración de sistemas urbanos sostenibles.

In the Book of Genesis there is a dramatic change in the world when God says: Fiat Lux (Let there be light)! Chaos was ended. In our everyday life when we hear a noise while asleep at night, we are afraid because there is no light, and if there is no light we don’t see anything, i.e., we do not know. When we turn on the light everything around us gets organized: light ends the chaos of darkness. In fact, we rely more than 80% on our sight sense to bring us what is happening around us.
Light is the genesis of visual perception, and colour is its vehicle. We understand the world around us by the organization of colour stimuli received by our eyes, transmitted to our brain and interpreted there.
We can say that colour is the form of space because it is through colour that we perceive the limits and the forms of our environment. Therefore colour should be studied, together with light, its origin, as the main actor in space perception, and therefore in architecture.
With these assumptions in mind we have to distinguish between Inherent Colour and Perceived Colour. The first is the colour of the surfaces, which could be read by a colorimeter, without the interference of the human perception or the outside lighting conditions. The second is the colour perceived by the human being, always different according to three variables: light, the observer and the surface. If any of these variables change, the perception will be different: if the light changes its position, or its characteristics, if the observer moves to another place or looks in a different direction, if the surface is placed under or above the observer, or with a different angle, etc.
Our work as Colour Consultant proves that the knowledge of this continuous variation in colour perception is a tool that we can use, rather than a disadvantage, to design better spaces for human life and comfort.
