L'Oréal's New Jersey research hub adds staff capacity in 59,000 fewer square feet

L'Oréal Groupe started with five outdated buildings in New Jersey and ended up with one. The LEED Platinum-certified reconstruction combines laboratories, offices and consumer evaluation space in a single integrated facility. The design team was led by S/L/A/M.

interiors+sources published the project on Nov. 11, working from SLAM's submission to the 2026 BUILDINGS and Building Design+Construction Elev8 Design Awards, where the firm was a Grand Award recipient. According to that account, L'Oréal's research staff once occupied five buildings totaling 316,330 square feet and now work in a single 257,185-square-foot facility, and employee capacity went up in the move.

That pairing is why a facilities director or corporate real estate lead should read past the photos. The useful questions are how a research building gets smaller and denser at the same time, and what else gets decided while the walls are open.

Shared labs instead of owned ones

The account frames the consolidation as a chance to reconsider more than operational efficiency. L'Oréal wanted a workplace where scientists, product developers and other specialists could collaborate more easily. That goal explains a lot of the floor plan.

Inside the research center, the planning puts its weight on proximity and adaptability. L'Oréal organizes its research into seven disciplines, which it calls Métiers, and they share modular laboratories fitted with mobile infrastructure and flexible workstations. Offices sit alongside the labs instead of in a separate building, and large amounts of interior glass give researchers and administrative staff a direct view of each other's work.

In practice, glass-walled labs line a corridor that takes daylight from clerestory windows, and natural light reaches the regularly occupied spaces. The glazing does double duty. It keeps disciplines visible to each other, and it lets daylight travel deeper into a large single building than solid walls would.

Modular labs with mobile benches suggest how the space math works. The published material doesn't break the capacity gain down by space type. Still, a building that lost almost a fifth of its area while adding people suggests each room gets more use, and shared labs could be one place where that happens.

The office side follows a similar logic. Huddle rooms, quiet areas, project zones and varied seating offer a range of work settings instead of one desk type repeated across the floor. Wellness rooms and mothers' rooms provide dedicated private space. Interior neighborhoods called villages use color, graphics and imagery drawn from global cultures to help people find their way around a large single building, and natural materials and biophilic elements run throughout.

One lounge, with curved sofas, shared tables and a suspended slatted ceiling, connects two distinct zones designed for individual workstations. Putting the casual space between the focus zones means people pass through it on their way somewhere else, which is a cheap way to make collaboration likely rather than scheduled.

Attendance policy may be part of the picture. L'Oréal's current US job postings, including one dated Oct. 28, 2026, list three days a week in the office as an essential function for office-based roles, with two days at home. That posting is for a commercial role, though, and says nothing about how the research center was sized.

Consumers on site, with their own route

The building also brings outsiders in. A Consumer Evaluation Center includes professional salons, testing showers, imaging suites and co-creation labs, where researchers test products with consumers under real-world conditions. Employees, visitors, consumers and service vehicles each have their own circulation route, which helps the campus control movement and keep people safe.

Testing inside the workplace has history at L'Oréal. Interior Design noted in 2017 that Gensler's L'Oréal office in New York included product testing labs alongside extensive break-out areas and even a virtual-reality room, reflecting the diversity of 30 brands. The New Jersey center takes that idea further, giving consumer testing salons, showers and imaging suites of its own instead of a lab tucked into an office floor.

Daily amenities are gathered into a few hubs. A Paris-inspired café sits with a concierge and a tech help desk, a pairing the account says centralizes select employee amenities while keeping branding and company innovation in view. A light-filled cafeteria and informal gathering spaces carry the social side, and outdoor terraces and volleyball courts give people a reason to step away from the bench. On a campus that used to be five buildings, pulling those services into one place follows the same consolidation logic as the labs.

Solar, storage and no new gas

The building has no new fossil fuel equipment. Its power plan combines on-site generation and storage, with building management and microgrid systems controlling how it performs.

The structure does two jobs. Building with cross-laminated timber lowers embodied carbon, and the material also makes large, adaptable interior areas possible. Exposed timber in shared spaces such as the cafeteria puts the material on show, where timber ceilings, clerestory windows and acoustic baffles sit above communal seating and sustainability graphics.

That second job ties back to the space math. Large, adaptable areas are what modular labs and shifting workstations need, so the structural choice and the density gain point in the same direction.

The site work covers water conservation and reuse, composting, recycling and stormwater management. On the reclaimed site, native plantings and pollinator habitats are meant to bring biodiversity back, and walking trails, tree-lined walkways, shaded plazas, open lawns and vegetable gardens modeled on wartime Victory Gardens make the grounds part of the workday.

A hangar in El Segundo took another route

L'Oréal has run a different experiment before. Metropolis reported in March 2023 that the architecture firm Blitz turned a roughly 130,000-square-foot aircraft hangar from the 1930s into L'Oréal's West Coast headquarters in El Segundo, near Los Angeles, with LEED Platinum and WELL certification as goals. According to the article, by Jessica Ritz, the energy strategy goes beyond California's Title 24 requirements, and the roof was prepared for photovoltaic panels, a hard job given the amount of glass in its sawtooth profile.

The program packed into that shell was dense. Most of the two-story volume goes to four L'Oréal brands that are based on the West Coast: Youth to The People, Urban Decay, Pulp Riot and NYX. Working salon equipment is also on site, along with studio and production space for creating content. The full-service L'Oréal ProLAb professional development academy is housed there too and has a public-facing entrance of its own. Amenities run from a gym and an outdoor edible garden to mother's and meditation rooms and a "barking lot" kennel.

That project kept what it could. Concrete floors, the hangar's huge hooks and other industrial pieces stayed in place. The team also narrowed its sourcing, aiming for material partners within Los Angeles County instead of the typical 500-mile radius for interior materials and furnishings. Concrete Collaborative supplied concrete terrazzo countertops and tiles, Bentley Mills supplied carpet, and Pair built custom conference tables and workstations manufactured in the L.A. area.

Set side by side, the two buildings answer some of the same questions the same way. El Segundo gave its public-facing academy a separate entrance; New Jersey gives consumers their own circulation route. Both include rooms for nursing mothers and food gardens outside. Both even nod to wartime history: El Segundo through references to the pioneering women who joined the workforce during World War II, New Jersey through its Victory Garden-inspired plots.

El Segundo kept an existing shell and left space for solar later. For operators whose space is spread across several outdated buildings, as L'Oréal's was in New Jersey, consolidation could be the better fit. For those with one large, sound structure already in place, reuse could keep it standing and may help on embodied carbon.

The line between the two routes is softer than it looks. The site plan published with the New Jersey project labels both renovated and new research facilities, which suggests consolidation there still put some existing building back to work rather than starting from a clean slate.

Questions to bring to a consolidation brief

For organizations running research or testing operations across several aging buildings, the New Jersey project offers a working benchmark. Before any design starts, three questions are worth asking.

First, set the target as capacity per square foot, not just square feet cut. L'Oréal's result counts because both numbers moved the right way. Second, list the labs that could share mobile infrastructure across disciplines, since that's where co-location saves space. Third, if consumers, patients or customers will come on site, plan their separate route early, because it shapes the site plan more than any finish choice.

For the New Jersey campus, the next number worth tracking is the measured one. Once the building has a year or two of operating data, actual emissions compared with the projected 1,200-plus metric tons will show whether the solar-and-storage plan works as designed.

That measurement has a context beyond one campus. Writing in MIT Sloan Management Review, Andrew Winston lists L'Oréal among the multinationals leading the CDP Supply Chain group, whose members are asking suppliers to measure emissions or set science-based carbon targets. For a company making that request of its suppliers, the research center's operating data would be its own version of the same exercise.
