“Tirana Lake” masterplan sorts out the planning of two areas at the south of Tirana, four hectares each. These areas are close but not adjacent, overlooking at an artificial lake. In order to answer the demand of high construction density, large platforms are designed to host important public functions at the first level and are treated as green areas on the top floor; on these platforms arise the residential and tertiary buildings. A new layer of the city with its streets, squares and courtyards is created on the platforms level; it allows stepping over the lake embankment and generates a new waterfront that can be used as a continuous path throughout the project.The overall design produce an urban artificial landscape in continuity with the surrounding nature. These green systems are spatial, visual, and functional connection areas and are displaced between several facilities: they are intersection for public and private space, daytime and night-time activities, and interior and exterior flows.While, on the north-side the “platform building” leans out on the lake, on the south-side a green platform develops towards the sky and becomes a vertical building that hosts the public library.
