A Tool That Thinks Back
A true conflict between parametric design and architectural authorship is on its way, but architecture still lacks a way of speaking about it openly. The software that was meant to emancipate architecture by being able to create highly intricate geometries, optimize structure for performance, and generate thousands of form possibilities in less time than it would have taken to create one drawing has quietly started to pose a dilemma, which architects would prefer to ignore. When the computer creates the geometry, who then becomes the architect?
The problem here isn’t that the machine takes over the person’s role. It is a different dilemma—the one of architectural authorship itself and its possible dissolution when confronted with parametric design.
What Parametric Design Actually Does
For clarity about the authorship issue, it is important to understand precisely how parametric tools work. In the traditional approach to design, there is a decision made by the architect—about form, proportion, materials, and structural considerations—that leads to a specific result. There is a clear link between the intention and the effect. Every line in the design is the hand of the architect.
With parametric design, on the other hand, there is a process in which the architect sets out a logic, an underlying system of relationships and rules that determine what is generated. It is not the architect who draws the building. Instead, the architect writes the system according to which the building will be generated.
The outcomes of parametric procedures can be quite amazing, achieving degrees of complexity and accuracy that human hands alone cannot accomplish, all while being optimized for maximum structural effectiveness and spatial experience as well as minimum environmental impact. However, the connection between the designer who established the initial conditions and the resulting geometry is very different from that of Mies van der Rohe and the Farnsworth House, or Zaha Hadid and the MAXXI in Rome. A mind did not create the design; it was created by a procedure, one whose outcome cannot always be fully anticipated by its creator.
The Question of Creative Identity
There are several reasons why this is relevant, though not all of them have philosophical roots. Architectural discipline is based on the notion of an architect’s creative identity—that a building bears distinctive features reflecting the mindset and approach of its creator. It is not only the technical expertise of an architect that clients hire him or her for; awards not only reward results but also intentions. Critical discussion presupposes that buildings can be interpreted as architectural statements. Parametric architecture does not eliminate architectural identity per se, yet it introduces certain complexities into the notion.
The complexity and inventiveness of the algorithm used to design a building become its defining feature, which makes it hard to discern what exactly the contribution made by the architect behind it was. Is he or she the inventor of the algorithm, the curator of the generated outputs, or just the one who picked one solution out of ten thousand? All of the options above may be considered legitimate ways of working in architecture, but not all of them are the same, and mixing them creates a peculiar case of ambiguous authorship.
Ownership in an Age of Shared Tools
The legal aspect of the question of authorship is no less ambiguous. Parametric modelling software is proprietary technology created by private companies that own the intellectual rights to any form produced by means of it. The involvement of the creators of the parametric design software—namely, the mathematicians, computer scientists, and engineers behind the software—goes unrecognized when an architect employs the generative algorithm to build a structure. This fact has not been adequately addressed by copyright laws in most countries yet.
And as the integration of artificial intelligence becomes increasingly entrenched in architecture, starting with parametric design and moving on to actual decision-making in design, the issue will only become more prominent. The discipline must come to grips with the true nature of authorship in this computational age before others do so for them—whether through legalities, software developers, or court rulings.
Parametric design is possibly the greatest tool that the architecture industry has ever known. The structures that have been created through parametric design are nothing short of incredible. However, this requires a certain amount of responsibility and clarity regarding accountability, which starts by having the courage to pose the question within the architectural profession.
