What RL&A. Architects does

RL&A. Architects (legal entity RL&Associés) is a Lyon-based architecture firm founded in 2014 that specializes in the conservation, restoration, and rehabilitation of historic monuments and UNESCO World Heritage sites. The partnership was established by three conservation architects — Didier Repellin (former General Inspector for Historical Monuments, ICOMOS member), Maïe Kitamura (School of Chaillot postgraduate), and Sixte Doussau de Bazignan (dual architect-engineer training, Richard Morris Hunt Prize laureate) — and operates from a single office at 5 rue Amédée Bonnet, 69006 Lyon. Its client base is heavily weighted to French public-sector buyers (municipalities, metropolitan authorities, ministries of Justice, Culture and Foreign Affairs, and DRAC regional offices) with additional mandates for private estate owners, religious foundations, and international institutions including the Aga Khan Trust for Culture. The documented portfolio covers roughly 59 projects across at least seven countries, ranging from €120k sculpture commissions to the €150M Grand Hôtel Dieu Lyon rehabilitation with Eiffage Construction.

The firm's offering is organized around nine service modules: diagnostic and preliminary studies, technical restoration know-how (stone, brick, plaster, sculpture, stained glass, roof systems in slate/lead/zinc/copper/tuile), historical research, rehabilitation and contemporary insertion, international heritage, gardens and landscape, furniture restoration and creation, emergency post-disaster heritage intervention, and 20th-century heritage. Underlying methodologies combine field diagnosis, petrographic and laboratory analyses, digital surveys, multidisciplinary engineering collaborations, and "light surgery" protocols for modern materials. A team of about 21 people — three credentialed partners, thirteen architects/designers with conservation specialisms, an art historian, a construction economist, and administrative support — delivers work as lead architect (mandataire) or conservation architect across civil, religious, landscape, and international typologies.

RL&A generates revenue almost entirely through project-based professional services contracts secured via competitive public-sector tendering and direct commissions for private and institutional clients, with no recurring or productized revenue stream. Pricing is negotiated per-project on a fee basis rather than on standardized rate cards, and the €150M+ figure highlighted on the firm site represents the underlying construction value of its documented portfolio rather than firm-level fees. The firm is privately held by its three founding partners, has no parent, no subsidiaries, no institutional investment, and conducts minimal active marketing beyond a bilingual website, the Villa Bonaparte monograph (De Luca Editore d'arte, 2019), and reputation-driven referrals within the heritage architecture community.
