The Art of Compact Living: How a Blue Box Transformed a Berlin Penthouse
There’s something profoundly satisfying about witnessing a small space transformed into a functional, beautiful home. It’s not just about maximizing square footage—it’s about reimagining how we live. That’s exactly what Bruzkus Greenberg achieved with their redesign of a 75-square-metre penthouse in Berlin’s Prenzlauer Berg. At the heart of this transformation is a multifunctional “blue box” that’s as clever as it is striking. But what makes this project truly fascinating is how it challenges our assumptions about compact living.
The Problem with Traditional Layouts
The original apartment was a maze of disconnected rooms, one of which lacked natural light entirely. The layout revolved around an unused fireplace, a relic of a bygone era that did nothing but eat up space. Personally, I think this is a common issue in older homes—spaces designed for a different time, when functionality took a backseat to aesthetics. Bruzkus Greenberg’s decision to remove the fireplace and internal walls was bold but necessary. It’s a reminder that sometimes, less really is more.
What many people don’t realize is that open-plan layouts aren’t just about creating a sense of spaciousness; they’re about redefining how we interact with our homes. By organizing the space around a central core—the blue box—the architects created a natural flow that feels intuitive. It’s not just a design choice; it’s a lifestyle shift.
The Blue Box: A Masterclass in Multifunctionality
The blue box is more than just a visual focal point; it’s the backbone of the apartment. It houses the entrance, a cloakroom, storage, and a built-in banquette—all while screening the staircase. What this really suggests is that every element in a small space must earn its keep. There’s no room for redundancy.
A detail that I find especially interesting is the use of stained wood rather than painted. The dark blue hue retains the natural grain, adding depth and warmth. It’s a subtle touch, but it speaks to Bruzkus Greenberg’s attention to detail. The color also ties in with the lighter sky-blue staircase and sloping ceiling, creating a cohesive palette that feels intentional rather than accidental.
The Psychology of Contrast
Peter Greenberg notes that the dark, low-ceilinged entry makes the main living space feel larger by comparison. This isn’t just a trick of the eye—it’s a psychological principle at play. Contrast is a powerful tool in design, and here, it’s used to amplify the sense of openness. If you take a step back and think about it, this is a masterclass in how to manipulate perception without resorting to gimmicks.
The mirrored surfaces throughout the apartment further enhance this effect. They reflect light and create the illusion of depth, making the space feel larger than it is. Even the column in the middle of the living area is covered in mirrors, effectively hiding it in plain sight. It’s a clever solution that showcases the architects’ ability to turn constraints into opportunities.
The Blurring of Boundaries
One thing that immediately stands out is how the sleeping area is separated from the living space by a light-blue curtain. It’s a simple yet effective way to maintain privacy without sacrificing openness. The curtain retracts fully into the cabinetry, allowing for cross-ventilation and a sense of continuity. This raises a deeper question: why do we insist on rigid boundaries in our homes?
The back of the bed’s headboard doubles as a desk, blurring the line between bedroom and office. It’s a nod to the realities of modern living, where spaces often need to serve multiple purposes. From my perspective, this is where Bruzkus Greenberg’s design truly shines—it’s not just about aesthetics; it’s about adaptability.
The Role of Color and Materiality
The bespoke butter-yellow sofa is a standout feature, but it’s not just a pretty piece of furniture. Its modular design allows for flexibility, and the cylindrical cushions fit neatly along the back or sides. This attention to detail is carried through in the accents—a glossy side table, a dining bench upholstered in Rox & Fix fabric—all of which tie back to the blue box.
What makes this particularly fascinating is how the architects use color and materiality to create a sense of harmony. The blue tones, mirrored surfaces, and natural wood grain work together to create a space that feels both cohesive and dynamic. It’s a reminder that great design isn’t just about individual elements; it’s about how they interact.
Broader Implications for Urban Living
This project isn’t just about one apartment; it’s a commentary on the challenges of urban living. As cities become more densely populated, compact spaces will become the norm rather than the exception. Bruzkus Greenberg’s approach offers a blueprint for how to make these spaces not just livable, but enjoyable.
In my opinion, the key takeaway is that small spaces don’t have to feel cramped. With thoughtful design, they can be just as functional and beautiful as their larger counterparts. The blue box isn’t just a clever solution—it’s a symbol of what’s possible when creativity meets practicality.
Final Thoughts
As I reflect on this project, I’m struck by how much it challenges our preconceptions about design. It’s not just about making a space look good; it’s about making it work better. The blue box is more than a design element—it’s a philosophy. It’s about finding elegance in efficiency, beauty in functionality, and opportunity in constraint.
If you take a step back and think about it, this is what great design should always strive for: a synergy between form and function, between the needs of the space and the aspirations of its inhabitants. Bruzkus Greenberg didn’t just redesign an apartment—they reimagined what’s possible in compact living. And that, in my opinion, is what makes this project so remarkable.
