BEHAVIORAL SYSTEMS & SPATIAL RESEARCH

UNIBAIL-RODAMCO-WESTFIELD (MFI DEVELOPMENT GMBH) PROJECT: Spatial Systems ORGANISATION: Unibail-Rodamco-Westfield (mfi Development GmbH) CATEGORY: Behavioral Research | [Foundation] [Human] | Changed how design teams review spatial decisions YEAR: 2014 – 2016 Behavioral Systems Research in Retail Environments Why Me Shopping centers are designed by architects and engineers. They optimize for circulation, sightlines, lease value, and fire codes. What they don't see is behavior—because nothing in their training teaches them to watch people the way a nurse watches patients. I came to this work from a different place. Before design school, I worked ICU shifts, reading the nonverbal signals of people who couldn't speak for themselves. I learned to see what environments do to bodies: where stress accumulates, where people hesitate, where the room fails them before anyone says a word. When I later studied industrial design under Marc Hassenzahl at Folkwang, I learned to frame these observations as interaction problems—not aesthetic ones. So when I walked through a shopping center, I didn't see what the architects saw. I saw the seating areas that were always empty despite being "well-designed." I saw the junctions where people consistently turned the wrong way. I saw zones designed for lingering that people rushed through, and families clustering in unplanned corners because that's where the real pause points were. The gap wasn't in the design. The gap was in seeing. What I Saw The organization had data: footfall counts, dwell time averages, heat maps. What they didn't have was interpretation. Numbers told them where people went. They couldn't tell them why people avoided the places designed to attract them—or why crowds gathered in spaces that weren't designed for gathering at all. Across three centers—Überseequartier Hamburg, Palais Vest, Ruhrpark Bochum—I watched. Not from control rooms, but from the floor. I tracked the difference between intended paths and desire lines. I noted where parents lost sight of children, where couples separated to browse, where elderly visitors gave up and sat on planters because the benches were in the wrong place. What emerged wasn't a list of problems. It was a pattern: design decisions were being made for an imaginary customer who moved logically, read signage, and followed architectural cues. The real customer was distractible, tired, socially negotiating with companions, and making decisions based on signals the designers never considered. What I Made Visible The value wasn't in the observations themselves. It was in making them shareable. I translated what I saw into frameworks that design teams could use: behavioral maps that showed where assumptions broke down, storytelling structures that gave each center a logic rooted in how people actually moved, and guidelines that connected spatial decisions to observed behavior rather than inherited convention. These weren't presentations that got filed. They entered the working language of the teams. Design reviews started asking different questions—not "does this look right?" but "what will people actually do here?" What Changed Decision-makers gained something they'd never had: evidence of how their assumptions failed, in terms they could act on. Spatial interventions followed. Seating moved. Wayfinding shifted. Service placements were reconsidered. Visitor engagement increased significantly, commercial performance improved measurably—but the real shift was in the conversation. Design stopped being about what architects preferred and started being about what behavior revealed. Three years after I left, the principles were still operational. Not because I was there to enforce them, but because they'd become how the teams saw.
