The objective of the new construction of a family house is to create a structure consisting of one underground floor and one above-ground floor. This design maximizes the use of the sloping terrain, providing stability and a natural integration with the landscape. In addition, the design includes a useful attic space, functioning as a gallery, which is created on the ceiling slab of the first floor above the vestibule, pantry, and part of the corridor. This attic space adds valuable living area without expanding the building’s footprint, offering a cozy and functional space that can be used for various purposes such as a study, reading nook, or additional storage.
