New Multi-Purpose Roof in the Urban Park of Abano Terme

Description

The new multi-purpose roof structure in the heart of the Urban Thermal Park of Abano Terme has been successfully completed, replacing the former Teatro Magnolia. Funded as part of the National Recovery and Resilience Plan (PNRR), the project stands as one of the most significant urban regeneration efforts in the region, with strong architectural, environmental, and social value.

Designed by Incide Engineering, the structure is light, elegant, and seamlessly integrated into the natural surroundings. It features a high-quality membrane roof supported by a state-of-the-art Mero spaceframe. The overall geometry has been carefully studied to ensure a high level of surface uniformity and optimal distribution of membrane tension, made possible by the use of nodal supports and pre-tensioned perimeter cables.

One of the most innovative aspects is the rainwater management system. Three central openings have been designed to collect and channel rainwater to the buildings below. Soft upstands integrated into the membrane guide the water in these openings, and structural ring cables allow the structure to absorb local stresses and efficiently transfer vertical loads to the main frame.

Unlike the initial design, which called for the roof to be divided into four panels, the membrane was instead produced as a single continuous piece, completely eliminating joints. This solution significantly enhanced the overall aesthetic, giving the structure a smooth, uninterrupted appearance.

The design and development of the membrane, tensioning systems, and cable layout were entrusted to Canobbio Textile, in collaboration with the engineering office formTL. Together, they meticulously addressed every technical detail related to the fixing systems, pre-tensioning, and the interface between the membrane and the steel structure, devising highly innovative solutions to ensure perfect alignment between fabric reinforcements and suspension points of the framework. The entire process was supported by advanced simulations and physical testing. All details were interactively developed and integrated in the Mero system. The Cutting pattern geometry has been derived from a smoothened surface. The nodal supports create then the local geometry by elastic strain. An analysis proved this concept prior to the final cutting pattern.

The installation was carried out by a team of highly skilled technicians, who tackled the logistical and operational challenges of such a complex structure with precision and expertise. The membrane was carefully unfolded, stretched and tensioned section by section, ensuring perfect alignment of every connection point.

With the completion of the works, Abano Terme gains a new iconic space—vibrant, inclusive, and open to the public—ready to host cultural events, performances, public initiatives, and moments of community gathering, all in harmony with the city’s thermal and landscape identity.

For both, Canobbio Textile and formTL, this project represents yet another symbolic and iconic achievement, now part of the architectural heritage of Italian cities. A work that unites engineering and beauty, innovation and sustainability—one we are proud to have contributed to.
