Design a modern and sustainable building that combines helical and wavy shapes with rustic and natural elements, fusing visual dynamism and connection with the environment. Use stepped, undulating balconies with planters filled with greenery, including small trees, shrubs and hanging plants, complemented by tempered glass railings that maximize views. It incorporates natural materials such as rustic stone for the bases, treated wood for structural details and cladding, and dark metallic tones to accentuate modernity. Design large areas with glass windows that integrate the interior with the exterior and allow in natural light. It uses sustainable technology with solar panels on the roof, rainwater harvesting systems, smart irrigation and cross ventilation. Frame the base of the building with green areas, stone paths and decorative elements such as rocks and gardens, which integrate a natural and warm environment into the design. Add outdoor recreational areas, such as raised wooden decks with rustic furniture and warm lighting details, creating a welcoming atmosphere. Design this concept to adapt to different scales, from a boutique cabin to a helical tower, keeping the aesthetic balanced between modernity, functionality and harmony with nature.
