vincent callebaut proposes to unite notre dame's nave, roof, and spire with glass canopy

in the wake of the devastating fire that ravaged paris’ notre dame cathedral, a number of architects and designers have presented proposals suggesting how the church could be rebuilt. the response of paris-based architect vincent callebaut seeks to bring science, art, and spirituality together. inspired by biomimicry, the design hopes to establish a fairer symbiotic relationship between humans and nature.

titled ‘palingenesis’, a name derived from the greek word for ‘rebirth’, vincent callebaut’s design aims to unite the cathedral’s nave, roof, and new spire. from the four gables, the original geometry of the 10-meter-high attic has been respected. meanwhile, the building’s triangular section and steep 55-degree pitched roofs gradually stretch to shape a vertical spire.

constructed with cross laminated timber beams pre-stressed with carbon fiber slats, the new oak frame seeks to use the minimum amount of material to ensure a low-carbon footprint while offering the greatest transparency. ‘transparency, sharing, and openness to our society’s development: such are the ideas conveyed by this new, diaphanous forest of notre dame, outlining the new face of the church in the 21st century,’ callebaut explains.

the cathedral’s restoration would transform it into a positive energy building that produces more energy than it consumes. the contemporary, three-dimensional gothic stained glass roof produces all the electricity, heat, and passive ventilation that the cathedral might require by combining passive systems and advanced renewable energies.

the new wooden frame is covered with a three-dimensional crystal glass canopy subdivided into faceted diamond-shaped elements. these crystals consist of an organic active layer, made of carbon, hydrogen, nitrogen and oxygen, which absorbs light and transforms it into power. this energy, stored in hydrogen fuel cells, will be directly redistributed throughout the cathedral. to avoid any greenhouse effect, the structure’s crystalline scales open to allow a natural air flow towards the top of the spire which mimics a wind powered chimney.

devoted to contemplation and meditation, the project features a garden cultivated by volunteers and charitable associations to help the most deprived and homeless parisians. callebaut estimates that up to 21 tons of fruits and vegetables could be harvested and directly redistributed for free each year, with a weekly farmers’ market held on the cathedral’s forecourt.

‘we advocate for an exemplary project in ecological engineering that feels true to its time and avoids a pastiche architecture that turns the city into an open-air museum,’ vincent callebaut explains. ‘circular economy, renewable energies, inclusive social innovation, urban agriculture, protection of biodiversity, without forgetting beauty and spiritual elevation: our reconstruction project feeds on such values to deliver a deep, conscious meaning.’

  • As one who studied Architecture for seven years, and worked in the field for decades, all I can say is I like it — but, I’d prefer seeing most, or at least some (perhapps in several areas) of the “roof’ floor” area open and the church interior exposed directly to the glass roof to allow the light in, and increase the parishioners perception of feeling and being closer to God when in the Cathedral.

  • Finally the spire is proportional to the building. The earlier spire was dwarfed by the scale of the building.I like the idea of fruit trees under the glass canopy to feed the poor rather than being a setting for the coronation of that dictator a Napoléon. After all ,feeding the poor is s Christian virtue. The history of Notre Dame was always about change.In 1220 they knocked down a wall they just built in order to add more stained glass windows.It went from a four story to a three story building. They also made changes to the transepts by using the Rayonnant Gothic style in vogue at that time. In the 19th century they added that dumbass spire I will never miss.

  • With the hope that we can agree to disagree (for now anyway), a pure travesty Dad, to may way of thinking. A church is a place for likeminded people to go inward and toward the spiritual aspects of life, it’s not about pizzazz. “Make « yourself » a light unto this world ».
    And about the trees ? no trees are going to survive, this is just a band-aid idea. Look first to the soil, the air, the water. And perhaps best to plant the seedlings nearby the place where they will be planted, hmm ?
    Sorry Dear, love you and love trees. Ed

  • Get over it people and read the details everyone. It is a brilliant plan! The original burnt down, cannot be copied as it was. This adds a whole new dimension to a magnificent cathedral rising like a phoenix into a modern space age. I absolutely love it!
