About
Phiform is an interdisciplinary architecture and design studio founded by Burak Koltukoğlu (PhD), dedicated to crafting purposeful spaces that enrich human experience and foster meaningful connection.
With a vision grounded in proportion, clarity, and creative collaboration, Phiform develops forward-thinking projects shaped by both analytical insight and artistic intuition.
Every design process begins as a dialogue — where needs, ideas, and context converge to shape more than a structure:
a story, a rhythm, a form with intent.
More than solving problems, we pursue balance.
We design for harmony.
This is not just form — this is phi-form.
