About Us

With a presence in Italy and international reach, our studio offers comprehensive interior design services for residential, hospitality, and commercial clients. We specialize in creative, timeless interiors that are tailored to reflect each client’s identity, values, and aspirations.

Every project begins with a deep understanding of context—architectural style, geographic position, and orientation—and evolves through close collaboration. Our process is personal, rigorous, and transparent: we involve our clients throughout the design journey to ensure that every decision aligns with both vision and budget.

Our team works in synergy with architects, engineers, and regulatory bodies to ensure that each space is holistically resolved—from its architectural bones to the final styling and decor.

THE COMPANY

Originally established in 2012 as Mariano Rossouw, the studio was born from a creative partnership and a shared vision for elegant, thoughtful interiors. Over time, as the practice evolved and matured, it naturally transitioned into ANTONIO MARIANO INTERIOR ARCHITECTURAL DESIGN STUDIO — a name that reflects Tony Mariano’s personal design philosophy, individuality and refined spatial storytelling.

Tony Mariano, an award-winning graduate of the KLC School of Design in Chelsea, London, leads the studio with a deep commitment to creating interiors that are not only beautiful, but also intelligently crafted to suit the lives of those who inhabit them.

Antonio (Tony) Mariano

FOUNDER AND INTERIOR ARCHITECTURAL DESIGNER

With a refined eye for detail and a passion for timeless beauty, Tony Mariano designs interiors that are both functional and emotionally resonant—carefully tailored to each client’s unique taste and lifestyle. He collaborates with property developers and private clients to create spaces that not only look exceptional, but also respond intelligently to real-world needs.

Antonio is known for his ability to interpret and elevate any aesthetic—whether contemporary, classic, minimalist, or eclectic. His approach is grounded in the belief that great design is not about imposing a signature style, but about revealing the personality of the people who inhabit a space.

From high-end apartments to boutique hospitality projects, Antonio blends elegance, comfort, and precision with a clear understanding of market value and long-term appeal. Every project is an opportunity to transform space into experience—tailored, authentic, and beautifully executed.

Our Design Ethos

  • We design interiors that are timeless, elegant, and deeply personal.
  • We prioritise sustainability, choosing natural materials and mindful solutions.
  • Every space is curated with intention - balancing function, flow, and beauty.
  • We support local artisans and celebrate craftsmanship with soul.
  • Our happy chic style blends sophistication with lightness and joy.
  • We believe a well-designed space should feel effortless, harmonious, and calm.
  • Our work begins with listening - every project is shaped by the people who live in it.
  • We don't follow a single style - what matters is thoughtful execution and enduring quality.

Client Reviews

Working with Antonio Mariano’s Team has taught me how your quality of life improve drastically with a well thought out and quality interior. Tony Mariano has inspired me to appreciate all the beauty around us and incorporate it in design. I have completed two projects with Mariano Rossouw and both were completed with professionalism, quality and attention to detail. I am looking forward to working with them again in future and strongly recommend Mariano Rossouw to anyone that is use to working with the best in town!

Steve Watson
Green Point House

Tony recently undertook a room renovation, a small project that has made a big difference to us. Tony’s attention to detail, care and creativity exceeded our expectations, and the result is nothing like we would have imagined – and everything we hoped for. His insight into our tastes made it possible to bring in new colours, textures and fabrics we would never had the courage to choose and combine, and which we love. Practical but beautiful, within budget and on time – what more could you ask for?

Client at Silos 3
Luxury Residential Apartment at the Silos District at the Waterfront

Mariano Rossouw was engaged by us to oversee the completion of our apartment at Silo No 3 in Cape Town. More than 200 snags were pointed out by their team and rectified by the builder before the apartment was finally accepted by us. Mariano Rossouw’s teamalso styled the apartment, did all purchases and supervised the installation. The final result is outstanding and very much matching our taste. It was crucial for us to have this type of quality support during the final phases of the project, since we do not reside in South Africa.
