Company expertise

  • Roofing

  • Paul Van Ostaijen Culture Campus in Leuven

    Lava architecten transformed an old mission building in Leuven into a place where circus arts, music, theatre, and dance coexist under one shared roof. Effective soundproofing is the precondition for the shared use of the facility.

  • Even though the main exhibition pavilion in the Giardini was closed, the 2025 Architecture Biennale featured more exhibits than ever before.

    Self-Exploitation in the Celebrity Circus

    At every Architecture Biennale, the curators face the same obstacles: a lack of funding, a great deal of red tape, and an organisation that ignores collective achievements. Why do they put themselves through this? We speak to Albena Yaneva, who spent a year observing the development process of the 2025 Biennale.

  • A vision for the future of Barcelona: Boltshauser Architekten have designed demountable street furniture made from concrete blocks for the Catalan metropolis. The blocks are made from recycled lean-mix concrete layers under roads.

    An End to Downcycling  

    In its current form, concrete recycling does little to help climate protection. The CO₂-intensive cement is lost irretrievably in the process. Boltshauser Architekten are working with a consortium from the Netherlands, Switzerland and Spain on the Respira research project to investigate how this can be avoided.

  • Stress tests have shown that re-use prestressed concrete slabs deflect significantly less than conventional reinforced concrete slabs.

    Slabs Under Tension 

    Concrete floor slabs have the largest carbon footprint of all building elements. In the past, the material was lost irretrievably during demolition. A Swiss consortium is now cutting standard square slabs from buildings due for demolition and using them to manufacture prestressed segmental concrete elements with a higher structural performance than new reinforced concrete.

  • Sergio Sebastián, What Does the Past Tell You? 

    Sergio Sebastián discusses the restoration of the Royal Monastery of Santa María de Sijena. How does he recreate the atmosphere without idealising a particular era?

  • Loose seating, light-coloured wooden fittings and warm colour tones transform the neo-Gothic interior of the Trinity Church into a bright and welcoming space.

    Knockin' on Heavens Door 

    Diezinger Architekten has transformed Nuremberg's Dreieinigkeitskirche (Trinity Church) into the GoHo Cultural Church. It is not only church services, christenings, and classical concerts that happen here; metal gigs are also welcome.
