Belgrade has long been a city read through its architecture. Neoclassical facades from the Kingdom of Serbia era stand alongside the heavy concrete verticals of Yugoslav brutalism, producing a streetscape that feels layered in competing visions of modernity. It is a city where the past does not recede so much as accumulate. Into this palimpsest, the Paris-based art and design studio Supaform has introduced EJE Belgrade — a 250-square-meter bar, listening room, and hotel occupying a stately 1920s building in the Stari Grad district, the oldest urban core of the Serbian capital.

The project positions itself not as a restoration or a tribute, but as something more speculative: an "autonomous station" imagined from a parallel timeline in which Yugoslav modernism never ended but instead kept evolving, growing stranger and more cinematic with each decade.

The K67 as conceptual engine

At the center of EJE's design language sits the K67 kiosk, a modular structure designed by Slovenian architect Saša Mächtig in 1966. The K67 was a product of Yugoslavia's particular brand of socialist self-management — a system that encouraged industrial design to serve public life at the street level. With its rounded, aerodynamic shell made of fiberglass-reinforced polyester, the kiosk could be configured as a newsstand, a ticket booth, a flower shop, or a telephone cabin. It was mass-produced and deployed across Yugoslavia and beyond, becoming one of the most recognizable pieces of civic design to emerge from the Non-Aligned world. In 2020, the Museum of Modern Art in New York added a K67 unit to its permanent architecture and design collection, cementing its status as a canonical object of twentieth-century design.

Supaform's treatment of the K67 vocabulary in EJE is neither nostalgic nor literal. The rounded, pod-like geometries reappear throughout the interior, but they have been scaled up, smoothed out, and placed in dialogue with materials and lighting choices that evoke science fiction set design more than municipal infrastructure. The effect is closer to a film production concept — a world where the modular optimism of the 1960s was never interrupted by the political fractures of the 1990s but instead matured into something more surreal and self-aware. It is retro-futurism in the precise sense: a future that was once imagined but never arrived, reconstructed as inhabitable space.

Sound as architecture

The auditory dimension of EJE is not an afterthought layered onto the interior design; it was a foundational element of the brief. The space is anchored by a pair of vintage JBL 4435 studio monitors — large-format, two-way speakers originally designed for professional recording environments in the early 1980s. Their presence signals that EJE operates as a "listening room" in the audiophile tradition, a venue where the quality of sound reproduction is treated with the same seriousness as spatial composition.

This integration of high-fidelity audio into a hospitality concept reflects a broader pattern visible in cities from Tokyo to Mexico City, where bars and lounges organized around dedicated sound systems have carved out a distinct niche. The listening bar format treats music not as background atmosphere but as the primary experience, demanding architectural choices — acoustic treatment, speaker placement, seating orientation — that subordinate conventional hospitality logic to sonic fidelity. In EJE's case, the marriage of audiophile rigor with a spaceship-inspired interior creates a sensory environment that is coherent on its own terms: enveloping, deliberate, and slightly otherworldly.

What makes EJE worth watching is the tension it holds without resolving. The project draws on a design heritage rooted in collective civic life — the K67 was, above all, a public object — yet deploys it inside a private, curated hospitality experience. It invokes a political and cultural context that no longer exists while refusing the melancholy that typically accompanies Yugoslav nostalgia. Whether this kind of speculative reinterpretation can sustain itself as more than an aesthetic exercise — whether it opens a genuine conversation about what Yugoslav modernism still has to offer contemporary design, or whether it remains a beautifully staged set piece — depends on questions that design alone cannot answer.
