Urban and Environmental Criteria. The objective of the project is to build the structure on site as a part of the natural surroundings. In other words, there will be no alteration of the already existing landscape or environment. In this way, the structure will add more value to the area in which it is implemented; visually it will enhance the harmony of the natural landscape, warmly attracting tourists and inhabitants of the city alike. Access. Having an atrium as an entrance will permit visitors to move in and view the surrounding landscape with ease. Acces to the open space of the atrium, as an area of events, entertainment and business is, by its architectural nature, easily visible, straightforward and uncomplicated; allowing abled and disabled alike to experience/use its elevators, pathways and leisure space. What it’s made of. As menitioned previously, the structure is composed of three main components or elements. The base or root of the center element is detached from the outside cover and has a surface volume of about 800 square metres divided into three levels . On the ground level, where the space is open and easily divisible, are the areas of commercial business and cultural events, exhibitions, a conference room (with a maximum capacity for 100 people), information and ticket booth as well as other services. On the second level there will be a library for adults as well as children together with an internet point/computer room as well as a bookstore. On the third level of the structure there will be a cafeteria as well as other related services. In he underground level there will be a parking lot containing a maximum of about 30 parking spaces (allocated to the employees working on the ground, second and third floors). The rest of the structure will rise upwards (115 metres), towards the sky, as does a budding seed, consisting of a steel covering with areas of titanium and green crystal, allowing for a transparency from both inside and outside of the structure, especially when using the staircases ( located alongside the elevator’s central route). The main staircase of the structure revolves in a spiral-like pattern around the central tower. There is also a main elevator situated in the center of the tower which carries passengers to the very top of the structure. Once arrived at the top, there is the option of walking along a steel bridge for a better view of the unfolding landscape. This steel bridge also joins with one of the large, white leaves to allow for visitors to go to the top of the structure using one route, and after passing over the bridge, to descend using a different route. On either side of the central tower there is a large white leaf made of both steel and titanium. The two leaves, naturally positioned in protective angles, are different in hight (136 metres and 170 metres respectively), and perfectly asymetrical. Both leaves also carry respective elevators on slight inclines to various viewpoints along the height of the structure. Comfort. Complete comfort is guaranteed in the following areas: regulation of temperature inside the structure, an adequate level of humidity and air movement. Since it is of utmost importance that the users as well as the elements inside of the structure are exposed to a healthy atmosphere, ventilation systems monitering the filtration and balance of air quality will be installed. As for the lighting, a portion of the light used to illuminate the internal part of the structure will be natural daylight, assisted by reflective panels which will also have the ability to diffuse the light in an indirect manner, rendering the atmosphere less harsh and more relaxing. The material used in the internal construction of the structure will also have noise- absorbing properties to lighten the sound of reverberating voices or heavy footfall.
