Tectonic Form

Plane: a two-dimensional, flat surface, where any two points on the surface can be joined by a straight line. Continuous.

Tectonic form shows the different intersections of points, lines, and planes. It can also express compartmentalization, where spaces are created by the points, lines and planes. In this form project, we were to use sheet metal and we were able to assemble by spot welding, using friction, or mechanical joints. The things to consider when making this firm were pattern, contrast, intersection, hierarchy, and containment.

I started off the form by making mock up models with bristol paper. My intent was to show pattern and hierarchy by using a series of isosceles triangles. In order to show hierarchy, I scaled down each triangle, so that it decreases its size in order. I cut slits at the base of the triangles in order to connect to each other.

It was then that I found out that the scale I was working on was unfeasible to be worked in the metal shop. Because my scale was smaller, it was difficult to bend the metals at the lowest angles. Due to the lower connections bending at the same time the scale changes, it was also difficult to use the slits as my joinery. I then decided to increase my scale and use spot welds as my form of joinery.


Spot welding can sometimes be cumbersome because it can get messy, thus lowering craft. I spot-welded tip of the base of the triangles and sanded it vigorously to remove the spot weld marks.

This form =also creates sharp compartments in the inside, due to the stacking of the triangles.

Contrast is also present in the form due the dark gap or depth between the triangles and the light flat planes.


Tectoform challenged my decision making process more than the other forms, because there were many different ways to solve a problem. Tectoform, like the other forms,also challenged my skill in craft. Compared to the planar flow form, I definitely had more control on my decisions and outcomes.
