Matched to the customer’s needs and wishes, a unique ‘house-in-house’ has been constructed on two levels above the city roofs. The well-planned roof extension fits into a private area with non-public spheres of retreat and an open residential area. Just an open kitchen block and a sofa landscape with a fireplace fill the generous area with a room height of over 3 metres. The pure elegance of the installations corresponds with the colour selection consisting of muted colours and colourful accents. The highlight is the unique roof terrace, which offers a magnificent view across the roofs of the city.
