Competition overview
Rome Rain Rooms invites architects, designers, and visionaries from around the world to reimagine how cities live with water.
As climate change reshapes weather patterns, Rome faces longer droughts followed by sudden, intense downpours – moments of abundance that often go to waste.
This competition challenges participants to transform those fleeting storms into civic rituals, turning rainfall into both a shared experience and a sustainable resource.
Participants are asked to design small, reversible pavilions that harvest and store rainwater while offering comfort and delight to the public.
Each "rain room" should collect at least five cubic meters of water per storm and direct it to where it is most needed – neighbourhood trees, gardens, or non-potable fountains.
Beyond its technical function, each pavilion must celebrate the sensory and social dimensions of rain: its sound, reflection, mist, and movement through space. Architecture here becomes a medium between people and climate, something that makes weather visible, touchable, and communal.
Eligibility and judging criteria
The competition is open to all.
Rome Rain Rooms seeks visions that turn the storm into a civic moment, reminding the city that resilience, generosity, and imagination can still flow together.
Designers may choose any location within Rome that supports their narrative, from a courtyard or market edge to a quiet corner of a piazza.
Proposals may also take the form of modular systems that can be installed in multiple settings, adapting to different scales and communities.
There is no fixed site. Designers may choose any location within Rome that supports their narrative — from a courtyard or market edge to a quiet corner of a piazza.
The most successful proposals will combine environmental logic with emotional resonance – demonstrating that architecture can teach, cool, and inspire all at once.
