Mia Spa, Beauty Spa and Perfumery Interior Design: Verena Sarnthein and Thomas Kühl, Photography: Maren Stöver Design of a Beauty Spa in Hamburg’s Kontorhaus district. A surface area of 650 sqm was to be furnished with a perfumery and several rooms for medical, beauty and spa treatments with waiting and relaxation areas. A recurring element of our design is the leaf shape. It inspired a light installation above the reception counter and various wall shelves for products.
