(at night:1.3) Design a gateway for a nature village, inspired by Iranian nature, and considering the specific climate and landscape of the Barajin region. The gateway should use local materials and embody sustainability in economic, social, and ecological aspects. The design should integrate seamlessly with the surrounding natural environment, resembling asymmetrical rock formations, mountains, and plants, rather than man-made structures. The functional part of the building should be located 3 meters underground to protect against the harsh climate and to preserve the scenic view of the plain. The gateway consists of two main parts: a symbolic part above ground, resembling natural rocks and boulders, and a functional part below ground, designed to meet practical needs while being sheltered from the cold and preserving the landscape's view.
