The existing buildings had already suffered a series of disastrous alterations when Foster & Partners took on the project. To get a coherent feel for the original building the studio found the original plans. Inspired by traditional local building work, the studio paid particular attention to a balanced proportion between each compositional element, the correct use of materials, and the rediscovery of work and finishings, such as Sgrafitto, specific to the context. The insertion of bow windows aims to give better views over the lake and mountain scenery.

A large number of ground floor shops have been reintroduced to liven up the building and encourage pedestrians. Careful attention has been paid to the interior décor, which combines the warmth and traditional values of the family hotel with the liveliness and comfort of the large hotel and the informal glamour of the design hotel. Each apartment is unique, reflecting the diversity of the original individual buildings, the needs of differing lifestyles, and the highly sophisticated local market. The Foster and Partners signature on the interior design is combined with more traditional elements, such as the fireplaces and wooden floors, familiar icons of Alpine style. Under specific request from Foster & Partners, Molteni&C, contributed an exclusive new edition of the Risiedo chairs by Luca Meda.
