Where work becomes renewable

For Boralex, we shaped 178 sqm in Paris into a living manifesto for green energy: a bespoke fit-out where 16 employees cultivate the future.

Concept

Offices reflecting renewable energy

Boralex is an independent producer of renewable energy operating across Europe and North America: wind, solar, hydroelectric, storage. In France, the company is the leading independent producer of onshore wind power with 85 sites in operation. The design and build project for the Paris headquarters was delivered in summer 2025, following the Bordeaux 2024 and Nantes 2025 projects.

Context

Boralex, an independent renewable energy producer, operates nearly 1,400 MW in France and ranks among the leading players in onshore wind with 85 sites in operation. In the summer of 2025, the group delivered its new Paris headquarters, 178 sqm on the third floor of a Haussmann-style building, for 16 employees.

The project is part of a trajectory begun in Bordeaux in 2024 and Nantes in 2025: three locations in less than eighteen months, all entrusted to Kytom on a design and build basis. The brief came down to a single phrase, carried through as a thread for signage and window graphics: « Renewable but never the same ».

An energy producer's headquarters that could not be a decorative green office

The challenge was not the floor area, which was manageable, but the risk of contradiction: an onshore wind producer set up in 178 sqm of Haussmann space in Paris, with mouldings, period parquet and the original ceiling height preserved, could not settle for a coat of green paint without undermining its industrial credibility. Three constraints framed the consultation.

Five months of non-negotiable works, slotted between the Bordeaux (2024) and Nantes (March 2025) deliveries. Seven work packages to be coordinated on a single R+3 floor plate without breaking the sequence: decoration, fit-out, bespoke furniture, signage, partitioning, paint, window graphics. A tight budget, which ruled out combining premium materials and showcased eco-design: a choice had to be made.

Two defining decisions: preserve the Haussmann structural shell, express identity through the skin

Rather than a heavy refurbishment, two guiding choices organised the works. First, no demolition: mouldings, parquet, load-bearing layout and original joinery were preserved. Consistency with the client’s low-carbon narrative became an argument of method, not an after-the-fact justification, and freed up budget for the items with high perceived value. Second, concentrate the visual signature on reversible surfaces: bespoke window graphics mapping the 85 wind sites in operation, interior signage in the brand colours, paint. Identity comes through the skin, the structural shell stays neutral, the lease stays exitable.

The space planning of the 178 sqm follows from these two decisions: reception within the preserved Haussmann sequence, focus and meeting spaces in fixed partitions on the façade side, an open collaborative zone treated with demountable partitions to absorb the evolution of the 16 workstations over the term of the lease. The bespoke furniture, calibrated to the seating and worktops, carries the same « Renewable but never the same » signature. The design and build contract made it possible to deliver the seven work packages over five months through a single point of contact, with no design-execution interface to arbitrate along the way — the condition for meeting the group’s schedule.

Headquarters delivered summer 2025, 16 workstations, five-month schedule met

At delivery, the Paris floor plate accommodates the 16 planned employees across the 178 sqm programmed, within the announced schedule. The design axis scores 4 out of 5 on the project radar, the highest in the file: it is the spatial translation of the energy narrative, rather than budget or CSR performance, that drove the perceived value. The choice not to display CSR figures (Kytom was still structuring its approach in 2025) in favour of proof through the preservation of the Haussmann structural shell proved more aligned with the client’s industrial reading than a displayed score with no grounding.

The headquarters extends the Bordeaux 2024 – Nantes March 2025 – Paris summer 2025 sequence: three Boralex locations fitted out by the same team in less than eighteen months, on the same design and build contract, with the same narrative thread « Renewable but never the same » adapted to each address.
