L2 Architectes

What L2 Architectes does

L2 Architectes is a French architecture partnership founded in 1968 and headquartered in Hérouville-Saint-Clair, Normandy, co-led since at least the current era by Arnauld Lorgeoux and Jérémie Guérin. The firm provides full architectural services — from competition entry through design and execution supervision (mission de base plus EXE, OPC, SSI, BIM phases) — across nine typologies: educational facilities, sports facilities, fire stations (CIS/CSP), residential housing (including social and student), healthcare, hotels/tourism, office/tertiary, industrial, and urban requalification. Its technical differentiators are bioclimatic design, sustainable construction using biosourced materials (wood frame, straw insulation), BIM methodology integrated from conception, and delivery against high-performance French certifications (RE 2020, RT 2012, BBC, HQE, Biosourcé).

The firm generates revenue through professional fees tied to construction cost (typically 8-15%) or fixed-fee missions, with no publicly disclosed pricing. Go-to-market is enterprise field sales executed through two channels: public-sector architecture competitions (concours restreints and open concours) and direct commissions from private developers. The client mix is dominated by municipalities, departments, regions, fire services, and HLM operators on the public side, and by developers such as BG Promotion, SPIRIT/FLAVIAE, and Kaufmann & Broad on the private side, with geographic reach concentrated in Normandy (Calvados, Manche, Seine-Maritime, Eure) and extending into Charente-Maritime, Charente, Guadeloupe, Loire-Atlantique, and Val d'Oise.

The firm operates with 8 employees, no external capital, and no subsidiaries. Marketing is minimal — a project portfolio website organized by typology, a LinkedIn page, and selective industry event participation (e.g., Norlanda's Cup). The operating model is consistent with a small, founder-owned professional services firm: relationship-driven, competition-led, with deep specialization in Normandy public infrastructure and a growing footprint in French overseas territories.
