Conceptual definitions are built on two simple ideas of ‘Pavilion Architecture in Natural Environment’ and Baroque Dialog’ of two main buildings on the site. While the first one defines the basic idea of spread urbanism in natural surroundings, the second ones highlights the importance of the major baroque museum. The old museum (with the baroque axis) should stay the most important building on the site (structurally, visually and functionally) (1). New extensions are a certain reflection of time, location, tradition and program (2). New buildings follow the existing urbanistic idea of the site, and are therefore designed as middle scale pavilions, visually distinct one from another. In order to do so, one has to design a certain amount of underground buildings (3). All the proposed buildings are functionally connected (4). A proposed concept is defining a new functional scheme of accesses, roads and paths – for better structural, visual and functional spatial organization (5). New program should solve existing problems and needs and add to more qualitative experience of the place (6).
