When Frank Nederhof, a property developer and former real estate agent, discovered a fixer-upper for sale near Amsterdam’s Vondelpark, his professional instincts told him it was an opportunity too good to pass up. “As a refurbishment project, it couldn’t have been better,” he says. The house, which dates from the 1880s, hadn’t been renovated since the 1970s, and its last owner, an elderly woman, had lived there for three decades.

The edifice featured high ceilings and a footprint three feet wider than most late-19th-century houses. Nederhof decided to gut the outmoded structure and divide the property into a few apartments to sell and rent, plus a live-work space for himself.

“The area’s fantastic and close to the heart of things,” he says. “Plus, my ground-floor apartment has a large private garden—something that’s pretty rare to find in central Amsterdam.”

He reconfigured the floor plan of the 1,350-square-foot space and added glass doors to separate his office from his living area. “As a real estate agent, I’m always aware that eventually homes will have to sell,” he says. “So I was careful to ensure that the office has access to both the hallway and the bathroom, meaning it’s a very versatile space. I use it for work, but it could be used as another bedroom.”

Nederhof added a steel beam to the main room, which encompasses a living area, dining space, and kitchen. The beam’s distressed finish adds textural contrast to the room and supports an 11-foot-tall, 60-foot-long rear extension that projects into the garden.

“I used ultracontemporary materials,”Nederhof says, “rather than taking the traditional wood-and-windows approach.” Steel-framed glass doors divide the space while providing views onto the back garden. His approach to interior lighting is equally considered: LED lights surround the perimeter of the dropped ceiling in the open-plan living, dining, and kitchen area, while mirrored glass bounces light around the narrow master bedroom, making the space appear larger.

Furnishings are deliberately neutral to keep the focus on the streamlined architecture as well as on Nederhof’s contemporary art collection, particularly metal works by Antonino Sciortino like the one hanging above the living room sofa. "The pieces of steel just slot together, yet it looks totally three-dimensional. It’s hard to find art that works with large pieces of furniture, but this is perfect." Reinforcing the gallery motif, Nederhof chose Bulthaup kitchen cabinetry for its floating effect.

Though happily ensconced in his abode, Nederhof isn’t content to rest idly. He recently purchased a 1930s garage down the street to transform into more apartments—further adding to his new neighborhood’s design capital.
