Our office was invited to the competition for the renovation of the Klotild palace and the Parisian yard inside. A modern hotel was to be planned in the historic building. From this duality we wanted to create an unity in the interior design, so we compared the specific design language of the two different eras. We have found that the common ways of the turn-of-the-century architecture and contemporary interior design is a combination of uncomplicated forms of simple geometric shapes, often in black and white color combinations. Along with these, but with the good use of today’s materials and furniture we vivified the atmosphere of the turn-of-the-century, and we also reinterpreted some exact elements -such as the hexagonal edged mettlachi mosaic of the covered shopping street. These black and white compositions, equipped with carefully selected furniture were made into cozy, homely spaces with the use of copper, leather and plants.
