Crafting Spaces with
Premium Materials

At Steinmarine, we believe that architecture begins with vision and materials that inspire. What started as a passion for timeless design grew into a company dedicated to providing exclusive natural stone, ceramics, and decorative bricks — always with the eye of an architect. Beyond materials, we offer interior and exterior design services, tailored to transform ideas into living spaces. Whether you seek only the perfect finish for your project or a complete design-and-material solution, our story is about bringing quality, creativity, and elegance together under one name: Steinmarine.

Our Journey

"
Steinmarine was born from a simple belief: every great space begins with exceptional materials. What started as a vision to source the world’s finest stone, ceramics, and bricks soon grew into a brand trusted for both quality and creativity. In the early days, our focus was on hand-selecting materials that met the highest global standards of durability, elegance, and performance. Soon, architects, developers, and private clients turned to us not only for the beauty of our products but also for the trust we built around them. As our journey unfolded, we expanded beyond materials — bringing architectural expertise into the heart of our brand. Today, Steinmarine offers not just carefully chosen building elements but also tailored interior and exterior design services, creating complete solutions for those who value timeless design and modern living. And our journey continues: with each project, we strive to blend luxury, authenticity, and vision — shaping spaces that inspire for generations to come.

Our Philosophy

We believe that

quality is never an accident . Every stone we source, every ceramic we select, and every brick we distribute undergoes rigorous quality control. Our team travels the globe to establish direct relationships with quarries and manufacturers, ensuring that we can offer not just exceptional materials, but also the stories and craftsmanship behind them.

Sustainability at Our Core

Environmental responsibility isn't just a buzzword for us—it's fundamental to how we operate. We work exclusively with suppliers who share our commitment to sustainable extraction and production methods. Our logistics network is optimized to minimize carbon footprint while maintaining the highest standards of material protection during transport

My Way

The Stein Marine team of material specialists and craftspeople in the Hamburg facility

When I look back to my early days in architecture courses, I remember being less focused on rules and more enchanted by the textures and colors of materials. I would hold a piece of stone or brick and imagine the lives it could touch once it became part of a home. That emotion still guides me today. As co-founder of Steinmarine, I lead a team of professional architects, but my personal mission has always remained the same: to create spaces where people don’t just live — they feel inspired, embraced, and at peace. For me, design is about creating atmospheres that last a lifetime.
