WHO AM I

Mélusine, Interior designer & expert in Space Harmonization

My passionate mission with MCOSI® is to support people who are aware that our homes are reflections of ourselves, and to give them tools to create tailor-made and comfortable spaces with a timeless style.

A graduate of the Lyon School of Interior Architecture since 2004, I hold a double degree in Feng Shui (Singapore & European Institute of Brittany). Born in Singapore, the birthplace of Feng Shui, I naturally
added this practice to my range of skills.

I have worked on interior design projects for major professional accounts and private individuals, as well as for furniture companies in Switzerland, France, Sweden, Dubai and Singapore.


I taught project-based design at the IPAC Design school in Geneva for 4 years.
