Text description provided by the architects. The former indoor tennis court has been stripped then covered anew with a whole envelope, composed of a unique two coloured material: gold metallic cladding moulds the existing volumes whereas the same black material underlines the new elements of the project. The cover lifts up owing to 4 discontinued lines letting in a diffuse and constant overhead natural lighting.
The new entrance slips under the South-West angle , progressively getting off the ground in order to gently welcome visitors; The envelope enfolds on the North facade and wide openings have been cut out in order to create a weight_lifting room largely opening on the park. The continuity of the envelope gives the building a visual unity emphasizing the harmonious correspondance between architecture and natural environment.
