This project is a timber assembly made of curved timber elements with the help of design modeling tools. The material specifications and the structural performance of the assembly were analyzed.

With the constraint of the tools available, a fabrication strategy was devised. The Design-Development-Strategy phase was carried out in smaller groups while the final assembly involved the students of the Digital woodcraft seminar – MAA01.


The process began with form-finding using paper strips and dry spaghetti. These were used to replicate timber in scaled-down forms.

Centralized forms

Mixed iterations

Density and shading

Glulamb Grasshopper


Few references were looked at to derive ideas for a temporary form



  • The idea was to create a tangle of curves that are visually complex.
  • Use of long and doubly curved elements.
  • Explore with density and twisting of linear elements.
  • Transform curves into long-span arches.



To test the bending of timber, we used 2mm thick lamella, glued them, and clamped it into position. It was let to dry until it took the final form.

FINAL PROCESS // Primary Beams

  • CNC milling 45mm timber to 40mm to avoid machining constraints
  • The 40mm thick timber was cut into 20mm x 40mm slices using the circular saw

  • Marking of Beams and supports for clamps

  • Creation of formwork

  • Gluing of Lamella
  • Assembling Primary beams
  • Primary Beam bending

  • The final result of Primary beams


FINAL PROCESS // Secondary Beams
