Ideja je da se u okviru Beton hale zadrze već postojeće namene usluga, poslovanje i kultura, i poveća upotrebni kapacitet objekta. Kao mehanizam za kontrolu ovakve strategije upotrebljena je  prostorna spirala koja formira opnu duž citavog objekta, i čije oscilacije (širenje i skupljanje) definišu odnos posotjeceg i dogradjenog volumena. Na mestima gde se namena menja spirala se prekida i deformiše  u zavisnosti od potreba. Istovremeno, ostvareno je dobro osvetljenje jedinica, inteziviran je kontakt medju nivoima i sa rekom, i šetalište je prošireno.
The idea is to keep the existing uses leisure, work and culture and expand their capacities. A new envelope, in the form of a spiraling strip is proposed and used as a mechanism to establish control over the expansion strategy.  Oscillations in strips’  width and height are used to establish relationship between the existing and new built volume.  the strip break and transforms according to change in use and user’s requirements. Simultaneously, the lighting is natural lighting is  improved, more connections between two main levels are formed and public esplanade is widened.
