The territory, suggested for placement of the International Business Centre with the hotel complex is located in the northern part of Yerevan. The platform is 40 meters higher the level of the city. The platform is a terrace from which there is a view on the capital and Ararat Mountain. Besides, the territory is a border between the urban part of Yerevan and its suburban area. The platform is also located on the border of the flat country of the city and the picturesque mountain area of its suburb. It was the territory of the projecting, which determined the concept of the complex. It is a place of meeting and opposition of «City» and «Nature». From one side we see the tendency of the «City» to try to get new natural territories, from the other side – the tendency of «Nature» to remain integral and penetrate into the town environment. In this connection a tension, a conflict and interpenetration of two systems take place. The processes of struggle, dynamics of opposition are reflected in the image of this complex. «City» is an arranged system of streets, houses, squares, and yards. This is a flat territory with well-defined lines of roads and rectilinear surface of fronts. Everything here has a clear structure.«Nature» is a system of picturesque mountain landscapes and dynamic water streams.«City» is a square glass prism, in which the hospital is located. It is absolutely flat and plane faced to Yerevan which symbolizes the systematicness and alignment of the city environment. Guests of Yerevan have the opportunity to view the process of the capital’s growth, as the rooms of the hotel apartments face the centre of the city. For them the city is a scene, where the play of life takes place, and the Bible Mountain is the main decoration. The proportions of the hotel-prism resemble the proportions of ancient stones - khachkars and invite to touch the history of these places. The ornaments, displaying on the glass façade resemble the ornaments of monumental stones. Glass plate is a mirror, in which the events of city life are reflected. «Nature» in this project is a stone part of the hotel complex. It is a trail, consisting of stones of different size and forming a massif. The brutal and raised parts of the building are contrasted to the glass plate. It continues the range of hills and mountains of suburban part of Yerevan. The agile stone tissue covers the glass plate, trying to release the territories occupied by «City». As for the dressing of inner and outer surfaces the traditional building material of volcanic nature is offered. Crude stone blocks of different size and color with rude natural texture may be used. Thus, the traditional for Armenia material acquire new quality and new look. The contrast of rectilinear and curvilinear forms of the building and also the contrast of materials gives us the feeling of opposition, dynamics and conflict of «City» and «Nature». In the part of complex where the apartments are located we create the background of old ancient settlements of Armenia, integrated into the mountain landscape. Small detached houses, picturesque streets are unique historic places for each town. Apartments are habitable blocks placed one on another. Each cell-block is an individual interim dwelling. The combination of these blocks creates inside yards-atriums, associated with cozy rural yards. The idea of old urban streets is supported with the staircase, leading in the complex from the lower platform of the city. In this case the ascent is a path in the mountains among the stony relief and picturesque tangle, where one can forget the city noise. The design idea of the territory of the complex is climbing to Ararat Mountain. The main arena is a broad street, located between the hotel complex and apartments. On the definite part the horizontal boulevard is continued with fixed ramp, leading to «the sky». The fixed ramp is an observation deck, a place of contemplation and reflection, the place of meeting with city and Ararat.
