AR .O

àr o is an independent creative consultancy studio in Milan, founded in 2020 by Andrea Steidl and Raquel Pacchini. It works from Via Contardo Ferrini 21, with a short name and a small footprint chosen on purpose: a studio built for consultancy rather than for a single design discipline.

In 2026 the practice announced that it is evolving into Rational Abstraction, the idea the name now reads as. Rational abstraction, as the studio defines it, means filtering out the specific, unnecessary details of a phenomenon, concept or system until its core, common or essential elements remain; the effect is broader generalisation, simpler decisions and less effort spent re-understanding similar problems. A new website is in preparation, and until then the studio keeps in touch by mail and through its Instagram account, @ar.o_design_studio.
