The peaceful world above ground finds its counterpart in the great underground machine, the generator that keeps the hotel complex alive. A hidden world, three abandoned tunnels leading into the hill, a place where functional but also common contents find their place, giving the whole complex an additional layer of value. The existing tunnels are preserved and converted into hotel facilities. The old tunnels are reflected on the surface through their traces - their projections are cascading squares, breaks in the series of above-ground units, and links of their streets. Instead of a big ship, a small town sprouts in the bay. Its callas follow the terrain and drown in it; its squares, gardens, and shops correspond to all the same functions of an island city. The units - houses - private and public, inhabited and empty, are partially autonomous as accommodation complexes, and closely connected programmatically. The INSULA 03 project questions what a Mediterranean city can be in a time of frantic tourism development. It offers an answer to the problem of the coexistence of the temporary community (tourists) and permanent residents by reinterpreting the model of tourist accommodation in the context of the city of Vis.
