We recognize design as an extension of how one inhabits space

As an Istanbul based design firm, Jeyan Ülkü Architects offers design solutions that will enhance human and space relationship by acknowledging space as an entity interacting with its inhabitants.  Founded by Jeyan Ülkü, we have been designing and delivering inspirational office, retail and residential spaces since 2000.

Each and every day, the conditions of spaces we inhabit change along with its requirements and demands. As Jeyan Ülkü Architects we take pride in anticipating these changes and aligning them with the requirements of our clients.

We always keep in mind that “every project” is unique, “every space” is exclusive and in JÜ Architects, we consider ourselves partners with our clients.

Our Approach

Primary phase begins as we are briefed by our clients. Based on this brief and our professional understanding of the space, an IDEA with a strong foundation emerges. The IDEA is usually difficult to pinpoint but easy to explore once it is found.

In DESIGN phase we aim to the meet the expectations created by the IDEA, keeping in mind the solid requirements of our client. In short, we translate the needs of our clients into physical space.

DELIVERY is a more technical part of our work. At this stage; design comes to life through selected materials, architectural details and technical drawings. This is where “design” becomes “build” within cost-budget and time constraints.
