A concrete box looses two faces wrapping two interior wooden volumes. The box looks like it’s floating trying to reach the city. The south and west façade walls block the sun light at uncomfortable hours. The box looses its face at east to show the wood boxes and at north to accentuate the city view. The top face protects the box from the weather. The underneath face adapts itself to the topography changing from being a slope and then the bedroom floor.

Some wooden tubes enclose the space. The tubes create a warm ambient underneath the concrete cover. The floor, the walls and the roof become one element making the space looks continuous. The first box, the bathroom, closes toward the access at the same time as it opens to the side views by the use of lattice. The side white screens show images projections. The second tube contains the lounge (bar, dinning room and living room). It opens to the corridor creating spaciousness and closes to the east façade emphasizing the city view.

The lounge tube manipulating artificial light creates different environments. This allows an interaction with the exterior as it happened at the colonial houses in Queretaro.

The bedroom and bathroom are located at first floor having more privacy. Crystal walls help to create the feeling that the tubes and the boxes floats. The side walls keep this private atmosphere.
