Odvajanjem unutrašnjeg od spoljašnjeg prostora počinje arhitektura. Uspostavljajući upravo te odnose zatvorenog i otvorenog uvek se javlja međuprostor, prelazni deo, granica ili mesto spajanja otvorenog i zatvorenog. Kako ta granica gubi obrise i svoju konačnost ona postaje zona pregovora, satkana od kompleksnih preklapanja slojeva značenja,materijala i programa. Tema projekta postaje upravo to, što povezuje ova dva pojma ali ih i razdvaja. Dolazi do raslojavanja i usložnjavanja granice, kreiranje ’’trećeg’’ prostora. Tako novi prostor posmatramo kako prostor mogućnosti koji omogućava transformaciju prostornih doživljaja. Postavljanjem dva suprotna elementa jedan uz drugi najviše dolazi do izražaja njihova različitost, ali i granica između njih postaje najtanja. Tema projekta na taj način postaje upravo ta pojava koja razdvaja dve različite vode. Vodu iz bazena i rečnu vodu. Uzevši u obzir da nije nužno postaviti ogradu/zid koji jasno postavlja granicu, granica između dve vode postaje sprud. Sprud kao nešto što fizički razdvaja vodu i ne dozvoljava njeno mešanje, ali i sprud koji daje mogućnost boravka upravo na toj granici. Projektovani sprud će svojom formom omogućiti različite načine korišćenja ne samo njega samog već i bazena. Tako promenljiv arhitektonični sprud oslobođen konačne korisne površine još više otvara zatvoreni prostor i stvara jedan otvoreni artikulisan prostor.
By separating the inner and outer space architecture begins, by establishing these relations between closed and open interspace allways appears, kind of transiton area or a point of melting of the open and closed. As this point loses its contours and its determinacy it becomes negotiations zone made of overlapping layers of meanings, materials and programs. Border delamination accures, and a kind of a”third” space is created. That new space viewed as a space of possibilities that allows the transformation of spatial experience. By placing two opposite elements to each other is most conspicuous for their diversity, but also the boundaries between them becomes the thinnest. The theme of the project becomes precisely this phenomenon that separates two different waters. Water from the pool and water from the river. It is not necessary to set the fence / wall that clearly sets the border, the border between the two water become sandbar. Sandbar as something that physically separates the water and does not allow its mixing, and the sandbar that gives the possibility to stay precisely on that border. The designed sandbar will enable with its own form ways of using not onlly itself but the poll as well. This diversible architectonic sandbar free of determined usefull aria opens the closed space even more, and creates an opened articulated space.
