Cosette El Hachem approaches outdoor and landscape design as an extension of architecture, not a separate layer. Her work focuses on creating seamless transitions between interior spaces and the outdoors, where terraces, gardens, circulation paths, and open areas are designed to feel intentional and fully integrated. She prioritizes spatial flow, views, privacy, and usability, ensuring that outdoor areas are lived-in spaces rather than purely decorative elements. Through careful selection of materials, levels, lighting, and planting strategy, Cosette creates landscapes that complement the architecture, respond to the site’s natural character, and remain practical and durable over time—resulting in outdoor environments that enhance both daily living and long-term value.
