About us

At SG Concept Architecture we bring together an original approach to design, quality materials and detail-driven construction in homes and commercial spaces.

In our studio in Göktürk, Istanbul, we offer complete solutions for villas, residences, private homes, offices and showrooms, from concept design to turnkey construction.

We treat every project with its own architectural identity, bringing aesthetics and function together in a timeless design language.

Founders: Sibel K. Onsekiz and Giray Onsekiz.
