ZDL is an architectural studio that, through general architectural practice, has encountered the widest number of architectural typologies ranging in size from micro shops and pre-fabricated accommodation units through family villas and residential buildings to public, social, and sports facilities (marinas, sports camps, stadiums, museums, hospitals, hotel complexes).

Foudned by Siniša Zdjelar in 2011 and since 2018, in addition to the main office in Rijeka in the Republic of Croatia, ZDL is also present in the Republic of Serbia with an office in Belgrade.

ZDL's approach to architecture, work processes, and cooperation on projects has conditioned our studio's constant growth and development. In addition to the artistic and technical development of services, a clear organizational structure was established to make team expansion part of the standard development routine. ZDl has won many awards and recognitions, such as the first prize for hotel Grabovac on the Plitvice Lakes, the third prize for Paromlin – the Zagreb city library, the Dezeen longlisted recognition for the office building Cedar in Kastav.

Through long-term planning that includes sustainable growth and development, we have reached a partnership between the two longest-serving staff members: Siniša Zdjelar and Antonija Plavotić.
