For over ten years we have been united by a shared enthusiasm for interior architecture and a passion for aesthetics and high-quality design and have always greatly valued our exchange of ideas in the conception and implementation of our various projects. We have now decided to merge our two studios of interior design and set up the company inside.

It is important to us that we listen to you, our customers, and understand your requirements and requests in order to then develop and realise your project together. Communicating closely with architects and specialists and working together with manufacturers to ensure a high standard of quality is thus of tantamount importance. 

Our scope of activities includes providing you with a place where you can feel at home, offices where you feel comfortable and are happy to be and medical practices where your patients feel welcome and well cared for.

We look forward to meeting you and your specific personal space.

My ability to understand space - whether on a plan or for real - is partly the result of my professional training as a classical dancer at the state theatre in Stuttgart, Germany. Being able to move within imaginary rooms, characters and situations is as much a prerequisite for working on stage as in interior design.

During my time in the showroom at the headquarters of Knoll International I was immersed in the world of architecture, design and interior design - and this became my passion. As part of a small team I then helped to set up Fleiner Objekt + Office in Stuttgart where I was responsible for interior design in the object section. My business clients included industrial companies (executive suites, reception areas and conference rooms), lawyers offices, doctor's surgeries, advertising agencies and many more.

After spending a lengthy period in Sydney, Australia, I moved to Zürich where I have lived with my family for over ten years and where I worked freelance, implementing many high-quality private projects, until the founding of inside.


Professional diploma of interior design (with honours) from the KLC School of Design, London.

My career started in international advertising. For many years I was responsible for the brand management of many well-known international companies.

My great love of design, colour and interior architecture ultimately prompted me to indulge my real passion for interior design. After successfully completing my degree I started work in Spain on the beautiful Costa de la Luz. The special light, range of colours, fantastic people and closeness to Morocco influenced my work for many yeas. Visits to my former home are still a source of inspiration.

I have now lived in Zürich with my family for over ten years. During this time I was able to complete many projects for private clients. At my own showroom I marketed high-quality ecological children's furniture from Europe.

Degree in interior design, graduating from the NY Institute for Art und Design in March 2009.
