Isern Serra has designed the interiors for Thinking Mu, a fashion store in Barcelona, Spain.

Thinking Mu is a sustainable fashion brand based in Barcelona, recognised for its commitment to ethical production and environmental responsibility.

The main design principles were to create a store focused on art and design that invites interaction and exchange, celebrating creativity and sustainability.

This philosophy extends beyond clothing into the very spaces that showcase it; the interplay of colour, shape and illusion transforms the space into an immersive, sensory journey.

Visitors are invited to explore, question their perceptions and experience sustainability as a tangible, interactive reality.

This project has been longlisted in the retail interior (small) category of Dezeen Awards 2025.
