About

ethos

cube and cylinder combination drawing with words, rigor and flow

MRTNZ | interiors cultivates spatial expressions for those seeking intimacy with their environment.

Guided by AOAIE, A Life Of Abundance In Ease: a philosophy that embraces presence, human connection, and a deeper harmony between people, space, and the natural world, our work balances richness with editorial restraint, craft and clarity.

Co-creation with our clients is at the heart of the process, listening closely, revealing what is not yet visible, and shaping spaces that reflect both function and possibility.

We believe luxury is not declared. It is felt, through thoughtful natural materials in their honest expression, precision, and environments that support the rhythm of experience.

Carlos Martínez

Founder, MRTNZ | interiors (Martínez, without the vowels)

Raised in a Mexican family in Southern California, Carlos’ early fascination with interiors began in an unexpected place. On weekends, his family would travel to Casa Leaders, a furniture showroom in Wilmington that catered to Hispanic families furnishing their homes piece by piece. The visits were practical—his parents would make monthly payments toward furniture room sets—but for young Carlos, the experience was something else entirely.

Each vignette felt like stepping into a different world. The careful arrangement of furniture, lighting, and textures carried an aspirational quality that stayed with him long after the visits ended.

Those early impressions planted a seed: that spaces hold emotional power, and that the environments we create shape how we live, gather, and dream.

Over the past fifteen years, Carlos has worked across residential and commercial architecture and interiors, guiding projects from early concept through construction and completion. Throughout that time, his curiosity remained centered on a simple question:

How can space support who we are becoming?

Today, that question sits at the heart of MRTNZ | interiors. Deeply connected to his cultural roots and to the natural landscapes of California, Carlos draws inspiration from places where landscape, architecture, and everyday life intersect.

After years within traditional architectural practice, he founded MRTNZ Interiors to cultivate a more personal approach to design-one where professional rigor and human intuition coexist. Because for Carlos, the ultimate measure of a space is not simply how it looks. It is how people feel when they arrive.
