Water-based structures are buildings or facilities designed to be partially or fully submerged in water. These structures can include floating homes, marinas, and offshore platforms. They are engineered to withstand the unique challenges posed by water, such as waves, currents, and potential flooding. These structures often utilize materials like concrete and steel, which are resistant to water damage. Innovations in design, such as buoyancy and stability features, help ensure safety and functionality. Water-based structures are increasingly popular in areas facing rising sea levels and urbanization, providing sustainable living and working spaces.
