This entire circle was built to hold water.
What happens when the water disappears — but the walls are still useful?
Large ground-level reservoirs are simple in principle: a huge enclosed volume stores water, while pipes, valves, access routes and maintenance equipment keep the system operating.
Once a structure like this is permanently retired, its scale can become a problem.
The walls are massive.
The footprint is enormous.
And the interior was never designed for people.
This concept turns those limitations into the design.
The center stays almost completely open.
Instead of filling the former reservoir with another large building, the old basin becomes a protected public courtyard surrounded by the original circular wall.
The maintenance route around the perimeter becomes a continuous walking loop.
Former technical spaces built into the edge could accommodate small community workshops, reading rooms, storage and basic public facilities without taking over the central space.
Even the old water infrastructure remains visible.
A large inlet pipe is preserved as a reminder that everything inside this circle once had a completely different purpose.
The trees are another important detail.
They wouldn't simply be planted through the old concrete floor. Large structural planters would provide the soil volume, drainage and irrigation needed above the existing slab.
A real conversion would also require extensive structural assessment, accessibility upgrades, drainage, emergency exits, utilities and investigation of the reservoir's former coatings and materials.
But the most interesting part is surprisingly simple:
the project doesn't need to fill the empty space.
The emptiness becomes the asset.
Water once occupied almost every part of this enclosure.
Now imagine giving that space back to the neighborhood.
Would you preserve the circular walls — or demolish everything and start again?
