From Babka Factory to Swiss-Brooklyn Sanctuary: Inside the Studio Seitz Williamsburg Loft

Main Facts

In the heart of Brooklyn’s vibrant Williamsburg neighborhood lies an architectural masterclass that bridges the gap between early 20th-century New York industrial history and contemporary Swiss minimalist design. Kevin Seitz and Rob van Wyen, the creative minds behind the furniture brand Studio Seitz, have transformed a former 1910 babka bakery into a dynamic 1,200-square-foot (111-square-meter) duplex.

Far from a conventional real estate acquisition, this sprawling loft serves a triple purpose: it is a deeply personal private residence, a functioning workspace, and an intimate live-in showroom for their meticulously crafted, Swiss-made furnishings. The project is the culmination of an ambitious, eight-year gut renovation—85 percent of which the founders executed themselves—that stripped away decades of uninspired, synthetic updates to reveal soaring ceilings, dramatic natural light, and authentic original timber beams.

The interior is characterized by a restrained, highly tactile material palette featuring dark kitchen joinery, blackened steel window frames, rich timber surfaces, and stainless steel hardware. Rather than relying on stark, modern sterility, Seitz and van Wyen infused the space with subtle structural references to Switzerland, pulling architectural inspiration from Zurich’s Helmhaus Art Museum, the country’s historic viaduct arches, and traditional alpine chalets. The result is a seamless hybrid of Brooklyn industrial grit and European architectural precision.

Chronology of an Eight-Year Labor of Love

The evolution of the Williamsburg duplex did not happen overnight. Instead, it unfolded through a deliberate, slow-design process that mirrored the founders’ approach to furniture prototyping.

Phase One: Discovery and Stripping the Layers

When Seitz and van Wyen first encountered the 1910 industrial building, they were not actively hunting for a loft in Williamsburg. However, the raw potential of the space—dictated by its grand scale, magnificent original timber construction, and abundant natural light—was impossible to ignore.

Upon taking possession, the duo discovered that a previous residential conversion had severely compromised the loft’s structural integrity and aesthetic character. Heavy, awkward concrete stairs dominated the interior, while synthetic bamboo flooring obscured the historic bones of the building. The initial phase of the renovation required extensive demolition to peel back these intrusive layers and expose the raw architectural envelope.

Phase Two: Structural Overhaul and DIY Execution

Determined to honor the space while optimizing every square foot, Seitz and van Wyen took on roughly 85 percent of the construction work themselves. This hands-on approach allowed them to test design ideas organically, living with temporary walls and spatial configurations before committing to permanent structures.

A major engineering challenge involved reconfiguring the main staircase. By straightening the path of the stairs, the designers successfully unlocked valuable ground-level square footage. This newly liberated space was carved into a private bedroom, a walk-in wardrobe, and a functional laundry area. Furthermore, the duo cleverly tucked insulation and electrical systems neatly between the exposed timber rafters, maximizing both ceiling height and clean structural lines.

Phase Three: Refining Details and Final Inhabitation

As the heavy construction wound down, the project shifted toward precision carpentry and spatial optimization. Unanticipated cavities within the loft’s historic layout were transformed into ingenious architectural features: a hidden mezzanine level was converted into a 3D-printing workspace and a cozy guest loft, while a former coat cupboard became a secluded, quiet study accessed through a frameless pocket door.

Living inside the construction zone over the course of eight years provided the designers with an invaluable meteorological advantage. By observing how natural sunlight shifted across the interior through all four seasons, they were able to custom-tailor an artificial lighting scheme that responds dynamically to the changing times of day and year.

Official Responses and Designer Perspectives

The philosophy driving the Williamsburg loft is deeply intertwined with how Kevin Seitz and Rob van Wyen approach their commercial furniture design. Rather than rushing through a standardized renovation timeline, the duo embraced the luxury of patience.

"One of the advantages of renovating your own home slowly is that you have the luxury of trying something before deciding whether it’s right," noted Kevin Seitz. "We work similarly with our designs; prototyping, living with things, and learning from them."

This philosophy of slow, thoughtful iteration dictated every square inch of the duplex. By testing layouts with temporary walls and observing environmental factors firsthand, the designers achieved an effortless visual simplicity that belies the immense technical effort required.

"A lot of work went into making the apartment feel simple," explained Rob van Wyen. "We reduced the number of materials and colours throughout the loft and repeated certain details. It helped connect spaces that had previously felt unrelated."

This commitment to cohesion extended to the integration of iconic Swiss and Scandinavian design elements, which were chosen not merely for aesthetic appeal, but for their ability to merge into the architecture. Discussing the minimalist modular storage, van Wyen added: "The system almost disappeared into the architecture."

Perhaps the most poignant aspect of the project is its dual identity as both a private sanctuary and a live-in showroom. For Seitz, traditional commercial showrooms often lack the emotional resonance needed to truly understand handcrafted furniture.

"Seeing furniture in person is incredibly important because there is a quality of the hand and a feeling that you can’t get from a photograph," Seitz explains. "In our home you get that, but you also get the wider context. A showroom lets you touch and experience a piece, but there is an intimacy that comes from visiting someone’s home and seeing how the designers themselves actually live with it."

Implications for Modern Urban Living and Interior Design

The transformation of the 1910 Brooklyn babka factory offers profound implications for contemporary urban architecture, interior styling, and the evolving concept of the live-work space.

The Rise of the Domestic Showroom

In an era dominated by digital e-commerce and curated Instagram feeds, consumer fatigue with sterile retail environments is palpable. The Studio Seitz loft redefines the retail experience by proving that luxury furniture is best understood within an authentic domestic ecosystem. By welcoming clients into their actual living space, Seitz and van Wyen pioneer a transparent, intimate model of commerce. Prospective buyers do not just see a sofa on a raised platform; they see how it interacts with morning light, timber floorboards, personal art collections, and everyday urban life.

Adaptive Reuse as Sustainable Design

Demolishing historic urban structures in favor of generic, newly built condominiums has long been a critique of modern real estate development. The eight-year meticulous restoration of the Williamsburg loft champions adaptive reuse at a granular scale. By uncovering original timber beams, preserving industrial volumes, and integrating modern insulation without sacrificing historical integrity, the designers demonstrate how industrial heritage can be successfully preserved and adapted for 21st-century residential comfort.

The Power of Micro-Architecture and Restraint

In dense urban centers like New York City, square footage is at a premium. The Seitz-van Wyen duplex demonstrates that luxury is not defined by excess space, but by spatial intelligence. Through clever interventions—such as straightening staircases, carving out hidden studies behind pocket doors, and transforming dead spatial cavities into functional mezzanines—the project illustrates how compact urban dwellings can achieve multi-functionality without feeling cramped.

Ultimately, the apartment stands as a monument to patience, craftsmanship, and cross-cultural dialogue. By weaving Swiss precision into the historic industrial fabric of Brooklyn, Kevin Seitz and Rob van Wyen have created more than just a home or a showroom—they have crafted a living blueprint for mindful, enduring design.
