The GAIA Hotel was faced with the challenge of turning its unused basement into something special for its guests. Hotel management opted for a spa area. As the space was rather small, they looked for lighting that would make it look large and bright. They quickly decided to use daylight as a light source. The space is now flooded with daylight thanks to several Heliobus mirror modules. Guests only have positive things to say about this spa area, located in the heart of the city.
