When the time came to renew their auction hall hardware, Lava needed bidding software that could match the demands of the floor. Every morning between 6:00 and 10:00, buyers bid simultaneously on-site and remotely, and the interface had to be instantaneous and unambiguous. A visual delay of just 100ms is enough for a buyer to bid at the wrong price. Designing for that level of precision, across three organisations with different workflows and hardware, was the core of the brief.

Before opening a design file, we visited the auction halls of all three cooperatives to observe the bidding process firsthand. Understanding how buyers read the interface under time pressure, how they track the clock and make split-second decisions, informed every design choice that followed. Speed and legibility were not secondary considerations. They defined the scope of the project.

We built the interface from its most critical element outward: the bidding clock. Treating it as an isolated design problem allowed us to prototype, test, and refine the motion and typography until the display was precise and immediately readable across all hardware configurations in use. The broader auction UI was developed only once that foundation was established.

Every UI state was intentionally designed, ensuring buyers could orient themselves instantly at any point in the auction flow, from a running lot to a concluded bid, without having to interpret the interface under pressure.

Lava's three cooperatives, BelOrta, Coöperatie Hoogstraten, and REO, now operate on one shared platform, serving both on-site buyers at bench computers and remote buyers via browser. The interface performs reliably under the pressure of hundreds of simultaneous bidders, with the clarity and precision the auction environment demands. One coherent experience across three organisations, with no room left for ambiguity.
