How a Former Kreuzberg Squatter Became Berlin's Most Innovative Adaptive-Reuse Developer

When Marcus Thiedemann first acquired a derelict printing factory on Mehringdamm in 2019, Berlin's commercial property market was riding high on startup euphoria. Today, as remote work and economic uncertainty reshape office demand across the capital, his contrarian bet on adaptive reuse looks prescient.

Thiedemann's company, Raum & Werk, has now converted five industrial sites across Friedrichshain, Lichtenberg, and Neukölln into mixed-use workspaces that blend affordable studios, collaborative areas, and light manufacturing—a model that stands apart from the gleaming glass office towers dominating Mitte and the Potsdamer Platz corridor.

"The traditional nine-to-five office is dead," Thiedemann explained during a recent walkthrough of his latest project, a former automotive workshop near the Oberbaum Bridge. "Companies now want flexibility. They want character. They want to share resources with creative neighbours."

The numbers bear this out. Berlin's office vacancy rate has climbed to 8.2% this year, according to Jones Lang LaSalle's latest market report, with prime real estate in central districts facing particular headwinds. Meanwhile, average asking rents have softened to €18 per square metre in secondary locations—down from €22 two years ago. Yet Raum & Werk's conversions command €16–20 per square metre, with occupancy rates consistently above 90%.

Thiedemann's approach taps into a broader shift. Larger companies including SoundCloud and Zalando are downsizing central offices, while mid-sized firms increasingly favour distributed, neighbourhood-based hubs. His Mehringdamm site now houses a graphic design studio, a video production company, three software teams, and a maker workshop—each paying modest rents but collectively generating steady returns.

The economics are compelling. Conversion costs run roughly 30% lower than new construction, and Berlin's building regulations—reformed in 2024 to accelerate adaptive-reuse permits—have eliminated bureaucratic drag. Property acquisition prices in eastern districts, averaging €8,000–12,000 per square metre, leave substantial margin for renovation and profit.

Yet challenges persist. Rising energy standards and heritage designations on some industrial buildings drive costs higher. Competition is intensifying: established developers including Howoge and TAG Immobilien are launching similar projects. And the market remains vulnerable to recession; if tenant demand weakens further, even innovative operators could face headwinds.

Still, as Berlin's office market matures and developers seek competitive advantages, Thiedemann's model—rooted in the city's countercultural heritage, shaped by pragmatism—may define the next chapter of the capital's commercial real estate story.
