Building above water means doing away with a part of construction that is quite literally the basis of most of our built environment: the foundation. In a world dominated by water, currents, and shifting levels are variables that simply cannot be ignored, which is why the most emblematic feature these projects share is their adaptability.
Instead of robust, deep bases – such as piles or caissons – designed to anchor architecture into the earth, floating structures frequently employ solutions like concrete pontoons or plastic drums to prevent the building from sinking. These are typically paired with anchoring systems to "fix" the structures, even if only temporarily, to a specific location.
While these structures are not necessarily lightweight – consider cargo ships, which weigh thousands of tons yet remain buoyant – they convey an aesthetic sense of lightness. Conversely, if "lightness" is often associated with delicacy, grace, or softness, many examples of water-based architecture offer a more "down-to-earth" alternative for confronting a harsh and urgent reality.

Why Doesn't Floating Architecture Sink?More than half of the planet is composed of water, and the majority of the population lives in its vicinity. These areas are increasingly affected by environmental disasters and rising sea levels, creating a scenario that poses new challenges to how we live in and design buildings for coastal or riverine regions.
Floating architecture can adapt to fluctuating water levels, floods, and diverse climatic conditions, creating a viable path toward addressing these issues. To expand your repertoire, we have gathered a selection of projects implemented directly on the water, ranging from residential and cultural to educational, recreational, infrastructure, hospitality, and public spaces.
