The interior refit for this 55m² apartment on board of the world´s largest private residential yacht was completed in 2019 during it´s dry dock maintenance in Spain. The interior design for the two bedroom holiday home was penned by Michael K Chen Architecture, who dubbed the apartment “Pied-à-Mer”.
The design draws on transformability and multifunctionalism as well as the aspiration to capture the modernist fascination with mid-20th century steamship design. For the design studio this was their first project on board of a yacht. So, due to the technical and operational safety standards required for projects in the maritime sector MKCA and List GC closely collaborated to realise the bespoke design ideas. ‘It was a bit of a learning curve, but our contractors were familiar with the ship, and we’re learning a lot about building on board,’ says Chen.
List GC was commissioned to handle the interior renovation of the entire apartment. In order to implement the new design by MKCA the complete apartment including all loose furniture and built-in furniture was cleared out and all raw walls as well as the electrical and installation lines were removed. The challenge in the interior outfitting was to ensure the technical functionality for all custom elements in the compact, transformable interior. To allow for optimal use of space many components are moveable and fold away or unfurl as necessary. For example, the entrance to the bathroom is hidden in the walls and can only be distinguished from the other wall panels on a closer look. Both master and guest bed were engineered to fold down from the walls and can be seamlessly hidden in the central unit when needed to maximise the space during the day. When tucked away, the space by the guest bed can be transformed into a comfortable sitting area with a fold-down table.

Additionally, all storage spaces and kitchen devices are integrated in the central element and meticulously concealed behind panels. Guaranteeing that all sliding or folding elements operate flawlessly is even on land no mean feat but poses an even greater challenge in maritime projects where you have to consider the pitch and roll motions of the ship at sea. Although rather unconventional on yachts, natural varnished oak was used for the flooring in the entire apartment. In light of existing fire safety regulations this entailed that all walls had to be made from fibreglass and aluminium. The entire apartment is illuminated by indirect lighting, creating a pleasant ambience. For the coatings a variety of varnish and RAL-colours were used. To achieve the desired quality and to ensure a smooth, seamless look of the ripped surfaces throughout the apartment, the List GC team first coated the even plane before finishing the corrugations on the ripped wall elements. The complete interior was produced in List GC´s in-house manufacturing facility in Bad Erlach.
