Off the southeast coast of Africa, more than 500 kilometers into the Indian Ocean, lies Madagascar — a country defined by extraordinary biodiversity, vast natural wealth, and a deepening energy crisis that leaves the majority of its population without electricity. It is here that designer Ahmad Eghtesad has set his most ambitious concept: the Baobab Waterfall, a floating mixed-use infrastructure that proposes to generate clean energy, rehabilitate society, and eventually evolve into a thriving resort — all from the open ocean.
The concept was developed as a competition entry for the prestigious Jacques Rougerie Foundation, which challenges architects and designers to imagine the future of maritime architecture. Eghtesad, working alongside collaborators Mohammad Aghaei and Nastaran Fazeli, drew his primary inspiration from the baobab tree itself — a native Malagasy symbol of resilience, capable of storing water and sustaining life in the harshest of environments. The architectural form mirrors this logic: wide at the crown, deeply rooted in its purpose, built to outlast the conditions that necessitated it.
Designer: Ahmad Eghtesad
At its core, the Baobab Waterfall operates as a continuous deep-ocean waterfall system. Ocean water is redirected and channeled through the structure on a massive scale, generating renewable electricity in volumes comparable to natural hydrological forces. The structure also integrates transparent greenhouses into its central tower, layering agricultural function into what is otherwise an industrial power plant. This dual programming — energy production and food cultivation — reflects a design philosophy that refuses singular solutions.
What makes the Baobab Waterfall genuinely provocative, though, is its social dimension. The structure is initially conceived as a rehabilitation center — a response to Madagascar’s overcrowded correctional facilities, themselves a symptom of poverty and energy-driven economic hardship. The idea is architectural optimism taken to its logical extreme: design not just infrastructure, but the conditions for social repair. As crime rates decline and the rehabilitation program matures, the complex is designed to seamlessly transition into a multipurpose resort and green energy hub, leaving behind a prosperous legacy rather than an institution.
Rendered with cinematic precision using Autodesk 3ds Max, Rhinoceros 3D, Grasshopper, and V-Ray, the visuals alone communicate the project’s ambition — dramatic contrasts between raw ocean forces and human engineering, scale that feels both monumental and quietly inevitable.
Whether or not the Baobab Waterfall ever leaves the realm of concept, it asks a question worth sitting with: what does it look like when architecture refuses to solve just one problem? Eghtesad’s answer floats somewhere off the coast of Madagascar, shaped like a tree that never stops giving.
