feature image revB -9, our proposal for the Roman Festival of Architecture, is located within the environmental system of the Tiber river and the Marconi-Ostiense district, characterised by the coexistence of residential and ex-industrial areas. Within this context, the monumental and disused industrial structures “the grand solitaries”, with their stories and memories, hold a great potential for the urban regeneration of the area. promotes new opportunities for reuse and regeneration, both in terms of material scale and urban scale. The proposal advocates for a new synergy, expressed through a network that creates connections and interdependence between the elements of the installation and the visitors. An organic composition, in harmony with nature, that can inspire people to pause and reflect on the contemporary heritage of a rediscovered area, reconnected to the city. is made of three key elements:

  • Reclaimed material
  • People
  • Nature




Reclaimed material proposes a new use of stone “waste” from local Roman quarries, discarded due to breakage or aesthetic defects. Each stone within the installation works as a structural element as well as part of the composition.
The design aims to promote a new sustainable approach towards the perception of the natural materials, giving value to their uniqueness and irregularity.. The stone “waste” is proposed as a new resource, mimicking the natural cycle, where everything is transformed and reused.



People are placed at the centre of the installation, as a key element of regeneration, defining the interstitial spaces between the reused elements.
Visitors are encouraged to interact with the networks connecting the stone elements, providing moments of conviviality whilst establishing a relationship between the built environment and the surrounding nature.



The installation is integrated within the vegetation of Marconi Park, near the Tiber river. The proposal aims to generate an opportunity for reflection, establishing an interdependent relationship between people, the built environment and nature.

Visitors will be invited to pause within the park, contemplating the course of the river and the natural landscape from a new point of view. aims to create a new destination, tracing unexpected connections in an interconnected space, seamlessly bridging the gap between nature and the built environment.

The role of stone

Stone is one of the most known and widely used natural materials in history, thanks to its aesthetic and functional values. It is a sturdy, durable material, resistant to fire and with excellent structural capabilities.
Its role has evolved over time. Traditionally used as a primary structural element, stone has more recently been relegated to a purely aesthetic function, impacting the environmental footprint of the extraction process and generating waste and consequently, costs.
If we could use the majority of the available stone, prioritising functional criteria over aesthetic, the economic and environmental impact of the material would be significantly reduced.


In recent years, advancements in the research of sustainable construction materials have identified stone as an excellent candidate. aims to promote a value-driven approach, combining the respect for the natural materials with the creativity and ability to adapt and optimise its use.
The intention is to “desacralize” stone and reintroduce it into contemporary architectural language, highlighting the potential of a material used for millennia but still young within the context of technological evolution.
