Architecture, Building and Structure Design Private Chalet Mountain Seasonal Residence by Fouad Naayem At the summit of a steep hill, lies a private residential project built to provide their owners with a secondary residence. The project makes the use of a difficult terrain, in order to create a practical and aesthetically pleasing living space. In fact, the triangular plot, which is located on a steep slope, has a setback line that limits design possibilities. This challenging complexity called for an unconventional design. The result is an unusual proportioned triangular building.
