Its teams are committed to offering you a fresh take on interior architecture. Our business: architects of beauty at the service of ergonomics and well-being.
 Your aspirations and constraints, whether ethical, aesthetic, economic or ergonomic, are the source of our motivation and creativity. We put our professional, precise and refined eye to work for our customers to satisfy the most eclectic of tastes. At Prime design, projects are developed around a contemporary understanding of what luxury is. Our conception of luxury is not based on cost or excess, but on the fundamental pleasure of living, of being immersed in visual and tactile beauty. A luxury that focuses not on ostentation, but on the well-being of an interior designed in its own image. Each project is an intimate and special jewel that we create and develop for our customers. It therefore requires our full attention, focusing on the spatial quality of the space, the relaxed sophistication of the finishes and timeless elegance. Its creation is based on technical precision, magnified simplicity, meticulous definition of detail and delicate textures, not forgetting the control of light. About Prime Design Studio "The artistic aspect is innate. It goes beyond ordinary thinking. It's a creative approach that will personalise your project and make it unique". Natacha Kowalak

Discover our realisation of the Villa Less Is More by interior designer Prime Design. A unique, elegant and atypical design. We work in Switzerland (Geneva), Haute-Savoie and the Var. Villa ROSARIO An exceptional Andalusian villa, reimagined by PRIMEDESIGN. Located just outside Marbella, Villa Rosario is a truly authentic Andalusian villa, centred around a beautiful traditional patio. Preserved entirely in its original state, the property is now undergoing a complete renovation and redesign by PRIMEDESIGN. The vision for this project is not to transform the identity of the house, but to preserve its soul and reveal its full potential. We have carefully retained the architectural character, proportions and atmosphere of this traditional Andalusian home, while introducing a refined contemporary approach to enhance its volumes, light and connection to the surrounding landscape. One of the key elements of the redesign is the relationship between the central patio and the sea. Although the villa enjoys an exceptional sea view, it was previously almost completely hidden from the main living spaces. Through a series of carefully considered new openings and sightlines, we have reoriented the heart of the house towards the Mediterranean, allowing the patio to become a true focal point — connecting the interior spaces with the sea and the landscape beyond. The result is a villa that remains deeply rooted in its Andalusian heritage, while offering a completely new experience of space, light and views. A unique residence where Mediterranean heritage meets contemporary design. SEE OTHER ACHIEVEMENTS
