Considering the increasing urban population, the limitation of available buildable land, and the intensification of environmental crises caused by climate change, the development of innovative living spaces particularly on water-based environments has emerged as a sustainable solution in contemporary architecture. The “Floating Habitat” project adopts an interdisciplinary approach to design a floating residential, cultural, and recreational complex that aims to meet human living needs while reducing environmental impacts and maximizing the use of renewable energy. Based on the principles of sustainable architecture, this project seeks to establish a balance between the natural environment and the built environment. The use of solar, wind, and potentially wave energy systems plays a key role in supplying the energy demands of the complex. In addition, the design of floating structures using lightweight, durable, and recyclable materials contributes to reducing carbon footprint and improving structural efficiency. In the residential section, flexible housing units with high adaptability are designed to respond to the changing needs of inhabitants. The cultural section includes exhibition, educational, and social interaction spaces aimed at strengthening human connections and raising environmental awareness. The recreational area provides spaces for relaxation, water-based sports, and collective activities, offering a unique living experience on water. From an environmental perspective, the project incorporates smart water management systems, wastewater recycling, rainwater harvesting, and optimized energy consumption to create a semi-self-sufficient ecosystem. Furthermore, the floating structure design allows adaptability to changing water levels and provides resilience against risks associated with rising sea levels. Overall, the Floating Habitat project is not only an architectural response to land scarcity in coastal and urban areas but also a model for future sustainable development, where the coexistence of humans, nature, and technology is achieved in harmony.
