I’m Giselle, an independent interior architect.

Originally from South Africa, with parents of Dutch and English descent, I now reside in the Swiss Romande region and speak English and French fluently.

As founder of GEM Design Studio, I believe the home should be a soothing and harmonious place, where you and your family can work, play, relax and unwind. 

Without being a slave to trends, my objective is to bring originality and richness to each project, not only with the choice of furnishings, lighting and art, but also with the use of a natural palette of materials and textures.

Whether it’s a one room or a full-house renovation or a new-build project, I work closely with you to create beautiful and functional spaces that are a true reflection of your design aesthetic and your lifestyle and that is able to evolve with your changing needs.

Please take a look at some of my recent work and get in touch to discuss how I can help you create your ideal home.

My story….

I’ve always had a passion for finding the most functional layouts for spaces and found myself as go-to for friends and family alike when they were faced with a renovation.

After testing the water with an interior decoration course with KLC School of Design in London, I completed my certificate in Interior Architecture with the Swiss Design Center in Lausanne, before launching GEM Design Studio.



As independent interior architect, I now find myself in the unique position, as member of a dynamic team at Maison Casagiu & Co, which allows me to draw on years of expertise in furnishings, lighting, paint colour consulting and bespoke pieces of art.
