Twelve finalist projects, one honorable mention, and five winning works were announced yesterday in Barcelona, marking the results of the 4th edition of the AADIPA European Award for Architectural Heritage Intervention.

Capable of transforming a facade or shaping a sculptural roof form, tensile structures test the limits of our imagination (and understanding of geometry). This week’s photo set features structures that rely on cables, anchors, posts and membranes to create expansive, dramatic spans of open space bathed in natural light. Stark shadows and fair curves make tensile structures particularly photogenic, as captured in this set of images from Christopher Frederick Jones, Marie-Françoise Plissart, Yoshihiro Koitani and more.

We love construction details! That's why this week's photos highlight the art of the synthesis of materials and the varied photographic products we can obtain by looking closer. Photographers like Joel Filipe, Marie-Françoise Plissart and Adria Goula, give us precise and beautiful exposure to wooden joints, steel structures, concrete details, curtain walls and more.
