Wood Stock: Patterned With a Purpose

The Flatiron Building in New York City is one of the most recognizable silhouettes in American architecture. Constructed in 1902, its narrow footprint and triangular design have made it a landmark for more than a century. Inside, however, decades of commercial use had taken their toll. When a major renovation was planned to convert the entire structure from office space to luxury residences, the design brief was clear: make the new look feel like it had always belonged.

That’s where Alex Oliveira entered the picture. Based in Oakhurst, New Jersey, Oliveira owns Arpa Flooring Design and does most of his work across New York City. Known for his experience installing parquet, chevron, and herringbone, he was brought in to lead the flooring work for one of the first renovated residential units in the building.

“This wasn’t just about putting in a nice floor,” he said. “The goal was to create something that felt timeless and rooted in the original character of the building, even though the space had been completely gutted.”

The 2,500-square-foot apartment was stripped to its bare structure. Much of the original material was removed, including the one-inch pine subflooring. More than three inches of self-leveling material were poured throughout. On top of that, crews installed a 10mm GenieMat for sound control, followed by Advantech OSB. With this base in place, Oliveira’s team could begin the installation.

The new hardwood was a custom European white oak parquet manufactured in Italy. Each panel was a large 48-inch by 48-inch square, designed with an intricate pattern inspired by a sample of fumed oak that had been found elsewhere in the building. “They didn’t want to go modern with it,” Oliveira explained. “They wanted something that looked like it had always been there. That’s what made this project different. We had to match that old look using new materials.”

Instead of aligning the parquet with the apartment’s walls, the layout followed a snapped line that ran from the center of the hallway to a triangular architectural feature. This detail, driven by the natural geometry of the interior, introduced several complex angles into the installation.

“We couldn’t follow the walls,” Oliveira said. “We snapped reference lines and worked out from there. We had to install everything in a way that flowed through the space without making it feel off.”

The main living areas received the patterned parquet, while the bedrooms were done in a straight-lay installation using matching oak. One of the biggest challenges, Oliveira noted, was keeping transitions clean and level between the two styles of flooring. “The layout was everything. We had to make sure every line made sense, and that meant measuring constantly and adapting on the fly.”

Before installation, the material was delivered to the site and acclimated for a week. Climate control had already been activated, ensuring that moisture and temperature levels were stable.

Color matching was another layer of complexity. “We made more than 10 samples,” Oliveira recalled. “The original fumed oak had a creamy tone, and we had to find a way to get that look using modern finishes.” Ultimately, the team landed on a blend of 75 percent DuraSeal Golden Oak with 25 percent Country White. The result was a warm, creamy brown tone sealed with a satin finish using Bona Traffic HD.

The Flatiron Building renovation will continue for some time. While this single apartment measured 2,500 square feet, the same approach will be replicated throughout the structure, totaling more than 100,000 square feet of custom flooring.

Oliveira said jobs like these are a reward for the years of work it takes to build skill and trust. “You don’t start your career with projects like this. I began 18 years ago as a helper, learning straight-lay first, then moving to patterns, then more complex stuff. That’s how you earn your place on a project like this.”

For Oliveira, the work is about more than just installing floors. “When I come into a space like this, I get to be part of bringing a building back to life. It’s a good feeling knowing that what we put in might last another 100 years.”
