AI-augmented Architectural Design


This research project aims to develop a toolkit for ML-based architectural design. Traditionally, architectural design involves combining and optimizing many criteria and constraints. For performance-driven design, architects and engineers create parametric design models to generate, simulate and evaluate many design instances, to gather performance feedback on design alterations. However, this is typically a hierarchical process, unable to deal with multiple concurrent objectives and only investigating a narrow spectrum of the design space.

Here, instead of tuning input parameters until the result meets certain performance criteria, we envision that machine-learned models of the design problem will allow us to find and explore design instances in the proximity of the specified performance goals.

We will develop and validate our AI-Augmented Architectural Design (AAAD) toolkit with a generic approach through case studies that are based on two different design categories. The first category concerns 2.5D surfaces, which are evaluated based on their fabricability (for 3D contour printing) and on environmental performance such as acoustics or sunlight protection, targeting architectural applications such as acoustic panels and façade panels. The second category is discrete element assemblies, which comprise load-bearing structures made of columns and beams. This category is evaluated based on structural or environmental performance goals.

The ultimate goal of this project is to augment the designer’s creative and analytical capabilities in the decision-making process by creating interactive design environments and thus revolutionizing computational design methods in architecture.

Design in Architecture, Engineering and Construction (AEC) can be described as an ill-defined (“wicked”) problem with many parameters, multiple constraints, and contradicting objectives. Traditionally, only a very small number of possible solutions is considered, created based on a human best guess or they are limited to blanket solutions. Parametric design tools such as Grasshopper allowed the automated generation of large numbers of potential solutions and the integration of performance measures. We aim to learn a generative model from the samples obtained from the parametric design that enables, given some desired performance attributes, generating a range of solutions that satisfy such constraints.

Proposed approach:

This will unleash novel design possibilities by augmenting the designers with insights into solutions they could not have imagined, excluding their unconscious bias, and allow them to combine human synthetic thinking with the analytic power of computation.


The SDSC leads the WPs related to the development of the ML/DL methodologies, which revolves around two different case studies that will boil down into a general methodology for generative design in AEC. The development of an interactive toolkit will is lead by the partners, with our contribution.

The proposed approach will allow the designer to discover new designs for given performance attributes, and interrogate the design space upstream.

The vertical garden project:
a) the outline shapes of the planting platforms are generated from the design parameters
(radii and constellations)
b) the design is subsequently assessed w.r.t. total area of the platforms, sun and rain occlusions
c) the final design visualized in context and scale.
