Wood on Wood: Centrality – top of the podium

With their work Centrality, Samuele Santini and Angela Darina Menchise won the 2026 Wood against Wood ideas competition. Without a single nail, screw or glue, they’ve designed a spiral-shaped pavilion to breathe life into the city’s urban voids.

Our cities are full of underused spaces. Squares, vacant lots, recreation areas – places that have lost their function or been left empty. This was the starting point for Centrality.

– We wanted to design something that activates urban voids, explains Samuele Santini.

He and Angels Darina Menchise, master’s students in Digital Architecture at Lund University of Technology, designed a spiral-shaped structure, supported by three vertical glulam beams, with CNC-milled elements assembled in an ascending spiral.

The competition jury was impressed by the work with structure and jointing. The pavilion has no screws, glue or nails; instead, wedged mortise and tenon joints and beech timber pegs hold the construction together.

–The project shows how digital tools can enable large-scale building with extreme precision – it became a kind of reference for us, says Samuele Santini.
