Nous Architecture | Design Studio is a design firm based in Istanbul, Turkey, led by co-founders and lead architects Sıddık Güvendi (b.1983) and Cihan Sevindik (b.1986). Our practice aims to integrate aesthetic, ecological, social, practical, and economic demands into memorable architecture that is in harmony with its context. We specialize in building design, including public buildings, housing, and business premises, as well as urban design and city planning, ranging from small urban interventions to large city plans. We have particular expertise in designing future learning environments, museums, and other complex public buildings in demanding urban settings, as well as additions in delicate historical contexts and natural surroundings. Our projects have won many national and international awards in competitions, and our lead architects have been awarded the Young Architect Award (2017) and the Turgut Cansever Award (2019).

Some of our other major and award-winning works include the Ulus Modern Arts Center (2021), Memorial Place for Healthcare Workers (2021), Muratpaşa Arts Center (2018), and Lüleburgaz Bus Station (2017).

In addition to our office work, Güvendi and Sevindik actively participate in various events, serve as jury members, and pursue part-time careers as studio instructors. They are members of the Chamber of Architects Section of UIA in Turkey and the Istanbul Association of Architects in Private Practice (IstanbulSMD). Furthermore, they contribute to the field by teaching and lecturing at schools of architecture in Turkey.

Sıddık Güvendi carried out his design practice at Collective Architects between 2011-2020 and won many awards, including eight first prizes. In 2017, he was awarded the young architect award at the national level. The other founding partner, Cihan Sevindik, founded OfficePan Architecture in 2012, where he won many awards, including eight first prizes, and was awarded the young architect award at the national level in 2019. The founding partners merged their design studios – Collective Architects and OfficePAN Architecture – under the roof of Nous Architecture | Design Studio in 2020.

Our team believes in collaborative management and an executive understanding, and we value collaboration with different architectural and multidisciplinary teams. Our flexible organizational structure and diversity throughout architectural competition practices allow us to provide simultaneous architectural services in different scales and topics.

We are open to cooperation.
