    Stage cover in the forest


Since the end of the nineties, the open-air-theatre “Cabrio” in Soest, the Netherlands, is used again for (theatre)-performances. In 2001, the municipality Soest assigned Tentech to realize a stage cover to facilitate performances during poor weather.

For the wonderful location in the woodlands nearby Soest, Architect Harmen Werkman designed a roof which fits perfectly in the natural surroundings. Cables suspended from two poles placed at the border of the woods, indirectly support the membrane, which gives the structure a floating appearance. A pressure arch made out of carbon composite is hung in the membrane to broaden the covering-surface. By not directly connecting the border of the membrane to ground-level, a natural scene is created.

A light-construction is suspended from the underside of the membrane. The frame follows the freeform-design of the membrane and can be lowered by electrical winches.

Textile architecture projects

The covering of a courtyard, canopies or stadiums… Tentech is part of the building team when textile and complex geometric shapes are used in new or existing architecture. Often we are responsible for a specific part of the design. In dialogue with the architect, contractor and client, we achieve an optimal contribution.

The design…

Our designs are characterized by sculptural quality and clean detailing, along with requirements of the location and usage of the structure. Combined they result into strong architectural concepts, in which aesthetics goes hand in hand with safe usage.

…and more

Our work doesn’t end with the realization of the technical design. We focus on all aspects of the design and production process that have an impact on textile architecture. Therefore, we are involved with all phases of the design process: from project definition, composition and preliminary design to the technical design, quotation, workshop drawings and maintenance. Supervising production, translating design into tailor made cutting patterns and connections, and assistance in the search and selection of the right market participants, are also part of our services. In our view, this is part of ‘modern craftsmanship’.
