The project carries out the integral reform and extension of a dental surgery placed in a mezzanine of building in the city centre of castellón de la plana. the main aim is to achieve a contemporary and functional image. in order to do that, the material chosen is the translucent glass, since it allows the sunlight coming from the façade to enter up to the heart of the dental surgery. furthermore, the walls and floor in white promote a feeling of lightness highlighting, at the same time, the blue corporative colour at the patient attention point. from the very beginning the project pursued the design of a place that transmits the clients the proprietaries’ serenity and confidence.
