IF Architects

What IF Architects does

IF Architectes is a privately held French multi-disciplinary architecture firm headquartered at 1 Avenue du Parc in Courbevoie (La Défense), founded in 1996 and operating with approximately 15 internal staff plus an extended network of external architects, landscape architects, and economists. Its core offering is the design and construction supervision of data centers, ranging from urban facilities to Pan-European campuses of more than 1 GWIT; the firm claims to have designed more than 87 data center projects, of which 23 have been built — the highest count in Europe by its own assertion — including the 135-hectare Marcoussis campus with a planned ultimate capacity of 255 MW. Beyond data centers it provides full architectural services for IGH high-rise office towers (notably the 152 m Tour Alto in La Défense), residential/logements, urban planning/urbanisme, and public equipment facilities.

The technical focus spans sustainable cooling systems (free cooling/air cooling, direct liquid cooling, and immersion cooling), ZAN-aligned site rehabilitation of declining industrial sites, bio-sourced materials, and systematic waste heat recovery into housing, offices, and public facilities. Flagship generalist work (Tour Alto) carries HQE, BREEAM Outstanding, Well, Wired Score, and RSE certifications, evidencing the firm's environmental-credentials capability.

Commercially, the firm operates a project-based professional services model: fees are custom-quoted, scoped per project, billed on multi-year contracts from feasibility study through final delivery, and sold directly (no resellers or digital channels) to enterprise data center operators, cloud providers, colocation companies, real estate developers, and public-sector clients across Europe — primarily France. There is no public pricing schedule, no disclosed revenue, no external institutional investment, and no parent company; ownership remains with founders Sandra de Lamotte and Bernard Lamy, alongside associates Hugo Ramos-Guerrero and Catherine Manche.

Direct peers

• Corgan: US-headquartered architecture firm widely recognized as one of the leading data center architecture specialists globally. Corgan is directly comparable as a similarly specialized, architect-led firm with deep data center credentials across hyperscale and colocation work.
• Page: Architecture and engineering firm with a dedicated mission critical / data center practice. Comparable as an architect-led specialist serving similar hyperscale and colocation operators in North America and increasingly Europe.
• Sheehan Nagle Hartray Architects: US architecture firm with a strong specialization in data center and mission-critical facility design. Comparable as a focused architecture practice whose business model and client set closely mirror IF Architectes' data center core.

Regional players

• Benoy: International architecture and design firm with significant European presence in retail, hospitality, and mixed-use developments. Comparable as a similarly-sized multi-disciplinary European architecture firm serving enterprise developers, though without a data center focus.
• Chapman Taylor: European-headquartered architecture firm with deep experience in mixed-use, residential, and commercial developments across the UK and continental Europe. Comparable as a multi-disciplinary European architecture practice with overlapping residential, IGH, and urban planning work.

Others

• Foster + Partners: Global architecture firm that is both a strategic partner (Hermitage La Défense) and an adjacent peer in large-scale, sustainability-led architecture. Comparable on the IGH/landmark-project side and on European operator relationships, though Foster's data center practice is more limited.

Broad incumbents

• Arup: Global engineering and design consultancy deeply involved in data center engineering and infrastructure consulting. Comparable on technical complexity and operator client relationships, with overlapping expertise in cooling, sustainability, and urban integration.
• HDR: Global architecture and engineering firm with a well-established data center practice serving hyperscale and colocation operators. Comparable as a large multi-disciplinary design firm working across the same operator client base, but with broader portfolio beyond data centers.
• AECOM: Global infrastructure consultancy with a major data center design and program management business. Comparable as a multi-disciplinary firm competing for the same operator-led campus projects, with deeper bench but less specialist focus.
• Gensler: Largest global architecture firm with an active data center and mission-critical facilities practice. Comparable on client overlap with hyperscale and colocation operators, though Gensler competes across many building types rather than specializing.
