Phi Design Studio Branding
A full rebrand for PHI Design Studio — a boutique interior architecture and interior design practice based in Cairo, founded by Sara Mostafa. The studio creates intentional, refined, and function-driven spaces, guided by the belief that architectural thinking and emotional refinement are inseparable: every client has a story, and it should be reflected in their space.
The identity takes its cue from the studio's name. Phi — the golden ratio — became the conceptual anchor of the rebrand. The logo mark is constructed from four interlocking letter P's that together form the Phi symbol, a dual reading in which each P also stands for one of the brand's four pillars: Premium, Intentional, Emotional, and Minimal.
