Who are we?

Sang Lee

Sang is a licensed architect in the State of New York, and a registered architect in the Netherlands. He studied architecture at the Illinois Institute of Technology (B.Arch.Hons.) and at the University of Pennsylvania (M.Arch.). Since 2005, Sang has been teaching architectural design and theory seminars at the Faculty of Architecture and Built Environment, Delft University of Technology, where he is currently Universitair Docent 1. In addition he has served as a visiting faculty and/or a critic, and lectured in numerous institutions and universities in the US and Europe. Sang has contributed several articles and chapters to international books, conferences, and journals. He conceived, edited and produced “The Domestic and the Foreign in Architecture” with the co-editor Ruth Baumeister in 2007. and “Aesthetics of Sustainable Architecture” in 2007. He is currently working on a new book “Architecture in the Age of Apparatus-Centric Culture.

Stefanie Holzheu

Stefanie Holzheu studied architecture at Bauhaus University Weimar and media architecture at the SUNY Buffalo. She is a registered architect in the Netherlands. Stefanie’s professional and research interests consist of not only architecture but also the position of technology and media. She is fluent in several multi-media programming languages and sensor-based automata. In 2011, Stefanie contributed a chapter (co-authored with Sang Lee) “Building Envelope as Surface” to the book “Aesthetics of Sustainable Architecture.” She also received the Netherland Architecture Fund’s Start-up Grant in 2012 for her research project “Fiber-Tech.”

What do we do?

Aleatorix is a multi-disciplinary experimental practice based in Rotterdam and Berlin. It seeks to explore new boundaries of architecture and material environment. The practice explores architecture as a progenitor of new living that includes environmental consciousness as well as technological potentials. The practice includes not only architecture, but also the systems and applications that augment conventional architectural environment and objects. Rather than insisting on the historical autonomy of architecture as discipline, the practice is interested in new relationships “connecting the dots” in a dynamic and innovative way and in the research and development of “con-figurations,” rather than isolated independent objects.

The structure is derived from geometric configurations of sea sponge. It is composed of internal axes of tetrahedrons that in aggregation disperse load pressures equally along three sets of parallel planes. The relative size and proportion can be indexed and metricized in order to produced structurally stable enclosures and volumes. The tetrahedral matrix distributes pressure applied at any one point throughout the entire structure. The relatively delicate structure gains remarkable strength. The project is in part inspired by Buckminster Fuller’s Geodesic Dome and "doing more with less."


Buffalo, work-in-progress


X-Changing Room brings about the user’s innate voyeur, whose primitive impulse reminds us that we all gaze. Crossing the threshold into the X-Changing Room, the user explores the transformative and discursive potentials of the surface as envelope. Information (or data) materializes and expresses itself through subtle ambient transformations in form, motion, sound, color, smell, temperature, or light. The ambient transformations become the immediate, intimate environment, in which the user is engrossed in exploration of the voyeur-self.

The TrackerBot is designed to detect, track, and tabulate environmental information. The shown prototype autonomously follows the black lines on the floor. The TrackerBot can be configured to carry various sensors and to respond respective to the environmental information such as light, sound, heat, and movement.

Immaterial or of minimum material presence that belongs to both the interior and the exterior; an interface that mediates between the interior and the exterior, reflecting the relations and flows between the two; a membrane that at once separates and connects media and substance, ephemeral and permanent, dynamic, and static; a primary means of understanding the ecological and the built environments, to locate ourselves within the web of relations of which we are a part. Phylogenesis of Generosity/ Outdoor exhibition curated by Warren Neidich


Rotterdam, 2010


This project is based on the relationship between music and architecture in their common characteristics of describing space. It aims to investigate agency and instrumentality for radical experimentation in architectonic composition. The project develops chance-based design techniques that incorporate sonic experience, a programmable aleatory automaton, and algorithmic transcription. The project resulted in two parts: the aleatory automaton that produces various combinations of notations and a software application that transforms video-captured notations (or colors) into surface compositions.

Contingent Frequencies

Rotterdam, 2009-10

Contingent Frequencies

The project was initially conceived in a collaboration with a jazz musician on the use of drawings for music improvisation. During the course of the initial experiment, PureData (PD) was used as a development environment in order to interlace live music with sampled sounds and digitally generated sound layers. After the experiment, based on the trials in PD, The project was further extended using Max/MSP/Jitter (a commercial version of PD) that will produce 3D double-curved geometries from sound. The project was intended to develop a simple software application that geometrically registers sound frequencies and amplitudes that can be prototyped for design and manufacturing of custom architectural panels. The developed application transforms the geometrical elements of a square (points and lines/ edges) and produces surface geometries in terms of scale, transformation and rotation that can be dialed in. The resulting surface geometries can be simply saved and output as an .obj file for further modeling and a variety of computer controlled machines.

Vierziaufvierzig: Drip-Wiggle-Stitch/ Kulturforum Berlin

Idea Sketch; Exhibition at BDA Gallery, Berlin, 2010


Invited by the Berlin chapter of the Association of German Architects (Der Bund der Deutsche Architekten, BDA), the idea sketch was featured in an exhibition at the BDA Gallery. The exhibition called for ideas on how to make the Cultural Forum area – composed of notable buildings and institutions such as Mies’s Neue National Galerie and Scharoun’s Philharmonie and Staatsbibliothek – of the city fit in with the 1990s development around Potsdamer Platz.


Antwerp/ Rotterdam, 2008


The project was a collaboration with musicians and conceived as a composition and modeling experiement using graphic scores and improvisation techniques. The project consisted of a music composition “Plan_B” and a custom Max/MSP patch that transforms a cube or a mushroom shape based on the music. With Leo Verheyen (trombone), Joris Bonis (sound sampling, patching and PureData) and Kathleen De Bodt (Max/MSP)

Parkstad Heerlen Regional Plan

Heerlen, 2007

Parkstad Heerlen Regional Plan

The project is a regional design study for the municipality of Heerlen, a former mining town in Limburg, the southwestern province of the Netherlands. The study consisted of two parts in urban and regional scales and was aimed at producing a development schemes in order to renew and reclaim the former industrial landscape and the main street as a means to revitalize the sleepy mining town. The design proposes a strategic preservation of the town’s old character while developing a distinctive main street that taps into the patches of green spaces and the rugged landscape. The drawings were exhibited at Kunstcentrum Signe in Heerlen. In collaboration with 12PM Architecture, Amsterdam
