Marc Koehler wants to build cities of the future, one flexible, sustainable community at a time


When Marc Koehler was a child, he loved spending the day drawing on huge sheets of paper. But rather than sketching superheroes or animals, he filled sheet after sheet with tiny homes and apartment buildings.

As an award-winning architect with his own architecture firm, Koehler’s childhood imagined cities have now developed into something far beyond a few lines on scraps of paper. Superlofts, the adaptable design for urban villages, are Koehler’s attempt at changing the future of our cities into an environment that fosters creativity, social cohesion, and a new economic model that doesn’t take our planet and its resources for granted.

This story is part of Architect Dialogues, an interview series by Freunde von Freunden and Siemens Home Appliances that explores current design philosophies, urban living trends, and global challenges with four award-winning architects and interior designers.

“Our projects always consider multifunctionality, a space that can transition over time, even if it’s just for one day.”

The view from the windows on both sides of the U-House, one of the first Superlofts ever built and home to Koehler, his partner Juanjo, and their dog Tommy, offers a first-class outlook onto the immense construction taking place in the Houthavens, a harborside neighborhood in the west of Amsterdam. Cranes move back and forth in the sky, the chorus of back-up beepers is nearly constant, overpowering even the loud squawking of seagulls and Tommy’s occasional, affectionate barks. The housing market in Amsterdam is nothing short of insane; tiny city apartments selling within minutes for prices double, and sometimes triple the amount anyone would have paid just a few years ago. It’s a housing environment almost opposite of the one that kickstarted the development of the first Superlofts. Back then, the economy was down in the dumps and construction nearly halted because there was simply no demand for new buildings. The only construction still going strong, was that of private homes on self-build plots scattered across the city. And private homes just happened to be a specialty of Koehler’s firm at the time. “We came across these lots for sale in the Houthavens,” he says. “We knew how to go about developing self-build lots and private homes and came up with this idea of stacking the self-build lots on top of each other in a building, like a huge Billy bookcase where everyone gets to design their own home. That set-up allowed us to access the financial resources needed to construct a new building, even in an economic crisis,” Koehler explains, adding that today, six Superlofts buildings can be found around the Netherlands, with another 15 planned all across the world.

“Buildings aren’t just functional constructions, they have to have a soul, an identity.”

This is how it works: everyone involved with constructing a Superlofts building is a co-creator. There’s the real estate developer, the architect, and the people willing to invest time and money into designing their own unique city apartments. The architect, in this case, Koehler and his team, provide a prefabricated concrete base structure, a model for the building, within which people can customize their own lofts, in whichever way they see fit. With a variety of predesigned building blocks at their disposal tenants can either lay out their homes from scratch or choose to work with one of the existing floor plans. The lofts in the building range from large, family-sized homes to small, more affordable studios, making the concept accessible to many different kinds of people. The residents design the communal spaces, like gardens or a lobby, together during workshops.

Koehler’s own Superloft takes full advantage of the concept’s modularity and flexibility. Two front doors open to a sunny, spacious living room with floor to ceiling windows that look out across the city. Groups of lush plants both inside and outside make the transition from living room to balcony almost seamless. A set of wooden stairs leads up to the open plan second floor, where a natural stone kitchen island takes center stage. The kitchen’s cupboards and practical appliances are tucked away in a nook, leaving the kitchen island as a clean and practical, multifunctional area. “Our kitchen island is supposed to be more of a social place for working, meeting, and just having a good time. We want to experience our kitchen as a place to hang out, as opposed to a place of labor or practicality. A place to connect,” says Koehler, as he walks through the kitchen towards the office tucked in the back. This space, too, is multifunctional, starting out as a gym in the morning, transitioning into office during the day, and switching to relaxing, early evening hang-out as the sun goes down on this side of the building with an ever-changing view of the Amsterdam harbor. “Our projects always consider multifunctionality, a space that can transition over time, even if it’s just one day. Using a flexible and open framework that can easily adapt to future changes makes a building resilient. And we need resilient, sustainable buildings if we want to live healthier urban lives.”

In the living room, Koehler points to a pull-up bar attached to the bottom of the second floor. It’s up quite high, but still reachable via a small jump from the couch. “Health is incredibly important to me, both physical and mental health,” he says. “Finding a balance between body and soul is a huge inspiration, and the metaphor of a building as a living being fits that perfectly. Buildings aren’t just functional constructions, they have to have a soul, an identity. You have to give a building time to come into existence, pay attention to the details and materials, make sure it’s healthy. I see our buildings as tools towards creating a balanced, healthy world.”

The Superlofts in the Houthavens already adhere to the concept of healthier urban living. Floor heating and cooling use heat from the neighboring industrial area and surrounding canals. The CO2 sensitive ventilation system only ventilates when necessary, and a smart hot fill system provides efficient and sustainable heating for the washing machine. The new Superlofts currently being developed around the world go even further. “With every Superloft, we try to get one step closer to a fully circular, sustainable building, connecting systems, and people to create new urban ecologies,” says Koehler.

Pointing to the left across the busy waters of the IJ, Koehler explains: “Right over there, just across the water in Amsterdam-Noord, are two projects in development, Republica and Poppies. These are the most circular, energy-efficient buildings we’ve ever worked on. They’re living ecologies where different value systems are connected to create an equal and balanced community.” Imagine a community like the one at Poppies or Republica. They might use compost from residents’ food scraps to nurture the apple trees in the community garden, which in turn can be used to make apple juice at the building’s public café, the peels of which will return again as compost. If you help with building maintenance or volunteer to work at the café, you might get a discount on your rent. One resident might be willing to do so, another one might be too busy and won’t mind paying a little extra each month. The system gives a sneak peek into a different kind of economy where the meaning of value is reevaluated, putting concepts like money, time, and even nature on an equal footing. The communal emphasis might not be for everyone, but for Koehler, his team, and the many enthused Superlofts residents, it’s the future.

“Right now, we’re working with an economic model based on exhaustion. Nature and our natural resources are being exhausted,” he stresses. “If we want to keep living on this earth, we will have to move to an economic model where everyone and everything has value. Labor, capital, energy, but also nature. So if you’re going to build new buildings, they absolutely need to be circular, future-proof and sustainable.” Listing all the different sustainable technologies already in place in the Superlofts gets Koehler visibly excited. His eyes shine when he mentions the EPC rating of one of the newest buildings. “It’s -0,34. Minus! That’s the lowest rating ever reached in the Netherlands. It means we have energy to spare, which we’re allowed to sell back to the grid.”

“If we want to keep living on this earth, we will have to move to an economic model where everyone and everything has value.”

With new Superlofts plans in cities all around the world, from Groningen to Berlin, Johannesburg, London, Newark, and Melbourne, Koehler and his team are ready to take their communal, sustainable living concept to a global level. “For us, as architects, Superlofts is a way to gather experience and apply everything we’ve learned to upgrade the world of architecture to a sustainable, fully-circular model,” he explains. “I’m convinced that I can influence and improve cities and societies with the buildings we create and believe architecture can and should always work to change the world for the better.”
