What Ledroit Pierret Polet Architectes does

Ledroit Pierret Polet Architectes (LPPA) is an independent Brussels-based architecture practice founded in 1997 (with firmographic data listing 1999) by Anne Ledroit, Vincent Pierret, and Cédric Polet, and headquartered at Rue Émile Claus 49 in Ixelles. The firm delivers full-lifecycle architectural services across residential, public, cultural, educational, and sports facility projects, with particular depth in social housing, heritage renovation, and low-tech sustainable construction. Documented credentials include BATEX 2007 eco-exemplary certification (Cygnes-Digue) and Passive 2015 standard (Candries), alongside biosourced material integration, material-reuse strategies guided by ROTOR, and reversible building design principles.

The firm generates revenue through professional architectural service fees, typically calculated as 8-12% of construction cost or on a fixed-fee basis, with public-sector work conducted under government procurement regulations. Its go-to-market combines direct engagement, public tenders, and design competitions, with documented participation in competitions for the WWF Belgium headquarters (2022) and the UNamur Design & Build student housing and sports hall (2025). Customer segments split between public-sector clients (communes, CPAS public welfare centers, SLRB social housing fund, universities, ADEPS sports federation) and private residential clients, supported by a stable engineering partner network (Greisch, MK Engineering, Energ-IR, ROTOR). The firm operates throughout Belgium with one international project in Le Thor, France, and has completed over 90 projects across its history.
