Christopher Sitzler Reworks a Fragmented 1990s Berlin Attic into One Continuous Room Wired for Sound

Attic apartments from the 1990s rarely get much respect. They tend to be a sequence of small rooms wedged under awkward roof pitches, each one cut off from the light that the slope should be delivering. In Berlin, Christopher Sitzler took one of these 76-square-meter units and reorganized it from the inside. The fragmented layout is gone, and in its place is a single continuous space, described by the architect as light-filled, that runs from kitchen to bed to bath without the usual corridor logic.

Opening up an attic is a familiar move. What makes 041BÖT Apartment worth a closer look is how the space is held together once the walls are gone. Sitzler does not leave it as an empty loft. He anchors each zone with a deliberate material: brushed stainless steel for cooking, warm teak and mahogany joinery for living and sleeping, glossy glazed tile for bathing, and floor-length sheer curtains running along the glazing. Running through all of it is a thread you notice quickly in Franz Grünewald's photographs. Speakers are built into the timber almost everywhere you look, which makes this as much an apartment for listening as for living.

One Room Under a Sloped Roof

The long timber dining table is the hinge of the plan. It sits between the steel kitchen and the lounge, so eating becomes the activity that joins cooking and relaxing instead of a separate room. Behind it, sheer curtains turn the glazing into a soft, even light source, and that diffused daylight carries across the whole interior.

Overhead, the slanted veneer ceiling does a lot of quiet work. Sitzler lets the roof pitch stay visible and wraps it in wood, so the geometry that usually makes attics feel cramped reads here as a canopy. The view through the doorway, past a round glass pendant toward the leather armchairs and the kitchen, shows the payoff: you can read the full depth of the apartment from a single threshold.
