situated on the lawn of the CEPT university campus in ahmedabad, india, WEsearch lab has built a temporary structure that explores a labor intensive, low-cost type of architecture in south-east asian countries. dubbed the ‘wormhole’ installation, the project has been developed with a budget of just 200 usd, using inexpensive building materials.

developing south-east asian countries typically don’t have access to cheap or large scale 3-axial 3D printing, 5-axial robot assisted printing, double-curved metal bending or robot assisted assembly infrastructure. on the other hand, they have an abundance of cheap manual labor, and readily available and cheap planar fabrication techniques. to minimize inflation of cost, free-form shapes need to be rationalized into planar parts which can then be fabricated using laser cutting or a CNC milling machine and assembled by hand.
the project explores a labor intensive, low-cost workflow of assembling laser cut pieces
located in front of the main library, which is characterized by strong horizontal and vertical lines, the installation begins with an orthogonal cube shape to respect the surrounding architecture. using this 2m x 2m x 2m box as a starting point, WEsearch lab then designed a wormhole-shaped faceted skin. to build the skin, 792 custom pieces (triangles with flaps) of 300 gsm paper pulp sheets are joined by 10mm wide staples and supported by a 15mm x 15mm x 1mm ms hollow section running along the periphery.
inside a cubic bounding frame, the surface is designed with a gradual introduction of double-curvature
inside the cubic bounding frame, the surface bends in both directions to produce two tube-like holes. the shape of the surface strikes a balance between respecting the surrounding graphical lines and drawing attention from passersby. from a distance, the peripheral cube lines draw the eye, while on closer inspection, the curvature of the self-warped holes halts the eyes of onlookers.

the digital aspect of designing the shape of the surface comprised three steps. firstly, 3D modelling software was utilized to conceive the free-form surface, then it was split into triangular pieces to allow the double-curvature of the structure. finally, a fabrication drawing was generated by flattening and numbering the triangular pieces, and adding flaps for staple connections.

the rationalisation of the double-curved surface into triangles is informed by the material properties of the 300 gsm paper pulp sheets. given the self-weight of the sheets and the size of the installation, the maximum allowed length of a triangle edge is calculated to be 350mm. for ease of handling, the minimum allowed length of a triangle edge is ascertained to be 100mm.

each quadrant of the installation is built with 198 triangular pieces, which are formed using a laser cutter. the half-cut flaps are then manually folded and stapled to each other. the triangles and flaps are numbered, which allows easy one-to-one assembly of the triangles. when all the four quadrants are fastened to the peripheral metal frame, the skin loses its amorphous nature and becomes a rigid tensile structure.
