Interior architecture & design expertise from a single source

As a well-coordinated team, Peter Peters and Miriam Sidler combine sound experience in interior design, interior architecture and holistic interior design - for private living spaces as well as sophisticated construction projects.

Inspired by traditional craftsmanship, culture and travel, they design timeless, vibrant spaces with character - beyond short-lived trends.

PETER PETERS OWNER CEO

As the owner and managing director of Peter Peters Interiors, I have been supporting our clients since 1991 with a clear focus on holistic interior solutions - from conceptual planning, organization and coordination to construction implementation.

My strength lies in strategic project management: I grasp complex requirements quickly, think in a structured way, coordinate precisely and guide all partners involved safely through all phases - from the first draft to the turnkey handover. In doing so, I combine technical understanding, entrepreneurial experience and high quality standards.

Specializing in high-end bed systems and advising private and professional clients - including architects, planners and hotels. With in-depth expertise and a keen sense of ergonomics, materials and design, I develop sleep solutions that are precisely tailored to people.

whether it's a comprehensive interior design, a complex renovation, a new build or targeted furnishing: my aim is to combine well thought-out interior design with real added value - functional, high-quality, personal.

MIRIAM SIDLER OWNER CREATIVE DIRECTOR

As an interior designer, I design more than just rooms - I create new lifestyles. My intuition, creativity and many years of expertise in working with colors, shapes, light and materials go into every project. My aim is to translate individual wishes into coherent, high-quality room concepts - with heart, sensitivity and a clear aesthetic standard.

For me, the design process begins with a precise, holistic understanding of the people for whom we are designing. After all, rooms should not just look good - they should reflect the character, lifestyle and attitude of their occupants. Personal interaction with our customers is therefore a central part of my work.

My roots in haute couture and design have shaped my approach: uncompromising quality, the highest level of precision craftsmanship and a keen sense of proportion and style. These principles flow into every detail - supported by a hand-picked network of manufacturers, suppliers and craftsmen who implement our ideas with the same dedication to perfection.

Every project is a new journey for me. And even after many years, it remains a fascinating moment when a vision becomes a unique space - one that not only impresses aesthetically, but also creates a tangible new quality of life.

KARIN GUSSET INTERIOR ARCHITECT, STRUCTURAL DRAFTER

Spaces influence our lives and our well-being. The creativity as well as the technical implementation fascinate me about my work.

My training as a qualified Draughtsman EFZ, further training at the Zurich School of Design, as well as training at the Institute of Interior Design give me the basis and knowledge for sensing the optimal geometries, symmetries, color compositions, materializations and light effects of a room.

Gained through many years of experience in various architectural offices I have the know-how of technical implementation using CAD plans and visualizations.

LEON ALEXANDER SIDLER ADMINISTRATION AND MARKETING INTERN

Even at a young age, I had an insight into my parents' working environment. I was particularly interested in how structured planning and efficient processes can turn a project into a functioning whole.


My professional career began with an apprenticeship as an EFZ confectioner at Confiserie Sprüngli. I then worked as a Junior Maître Chocolatier and led courses at the Lindt Home of Chocolate in Kilchberg. This time shaped my ability to take responsibility and work in a structured team.


After my military service in 2021, I completed an internship in the administrative area to further develop my knowledge of organization, communication and project work. This gave me an in-depth understanding of the processes in the family business and I developed a growing interest in business contexts.


I am currently studying Business Administration HF to supplement my practical experience with in-depth specialist knowledge. My aim is to use this combination in a targeted way to take on long-term responsibility in the company and contribute to its professional development.
