01-EARTH RECREATIONAL: THE CONCEPT
The recreational area of the galactic suite space-resort is planned in the southern side of Ronde Island with a strong topography that provides the best views over the technical and training area on the other side of the channel. The buildings are understood as  big caves that dig into the ground and let the natural light bath the interior through huge holes on the top of these concrete structures. The complex is then conceived as an agglomeration of these structures each of them is accommodating big room for one of the recreational activities.  The entrance hall and shops are placed on the ground floor by pedestrian path and the road and parking for electrical cars. From there the visitor can access the some rooms on this floor with  conference halls as well as restaurants and cafeterias and lookouts. The upper floor is dedicated to other rooms with the different halls of the museum, the kids space lab, simulator halls, planetarium and 3d cinema.

02-EARTH RECREATIONAL: THE CONSTRUCTION
Sustentation system: Ronde Island has rock layer not very deep into the ground whereas it will be easy to fund any structure decided. A further study on the ground composition will be undertaken in order to decide the final technique for funding.
Structure system: the buildings are conceived as concrete caissons that are caved into the ground to provide inertia.
Enveloping system: the structural walls are also the enveloping system from sides. The top of the walls are not continous but they deploy a set of beams in several directions that let the light in at the same time that provide smaller span structures to build the glassed roof that covers each module.
Finishing system: the interiors will be warm and light to provide homogeneous illumination for the museum and  simulators areas. Restaurants and cafeterias will be finished with glass and steel to accompany the space tourist in his futuristic trip.
Installations system: digging into the ground the building maximizes the passive systems for conditioning the air through a sustainable study that takes advantage of ground mass to low the temperatures and the humidity. Therefore a minimum energy will be employed on this purpose.
