In the European architectural landscape, few careers are as deliberately cross-cutting as that of Marie Cardwell de Bryas. A graduate with a BSc in Architecture from the University of Bath and a Master of Architecture from the University of Edinburgh—two of the UK's most selective programs—and registered with the French National Council of Architects (CNOA) as well as the UK's Architects Registration Board (ARB), she honed her expertise over several years at Stephen Taylor Architects, a London-based firm founded 25 years ago and recognized by the RIBA for the exceptional quality of its contemporary social and cultural projects. In France, where the National Council of Architects lists 30,300 registered architects in 2025, Franco-British dual registration profiles remain extremely rare, less than 200 according to industry estimates.

"I was working at an agency that had been around for over twenty-five years, with an established name, portfolio, and credibility," explains Marie Cardwell de Bryas. "I wanted to return to France, and Stephen Taylor and I decided together that I would open a French branch. This allowed me to have both the entrepreneurial side and the security of a recognized structure." The venture, launched two and a half years ago, has paid off: the Paris office now has about fifteen active projects, spread between Paris and the south of France. "We are working in the Cévennes, the Camargue, and near Moissac—areas with extraordinary built heritage but also considerable energy challenges," she specifies. "Our projects cover heritage renovation, energy retrofitting, and new construction. Each site requires a different dialogue between the existing and the contemporary."
The French energy renovation market presents a colossal challenge: according to Ademe, 5.2 million homes are classified as "thermal sieves" (DPE classes F and G) in 2025, and the government mandates the renovation of class G homes by 2028. It is in this context that Marie Cardwell de Bryas's expertise finds particularly fertile ground. "I am also very interested in urban planning and environmental issues," she confides. "I write articles for various magazines and publications, such as the OECD's Cogito blog." This dual role—site practitioner and essayist published by an international organization of 38 member countries—lends her rare legitimacy in a sector where theoretical discourse and on-the-ground reality too often ignore each other.

Stephen Taylor Architects' London portfolio demonstrates a constant commitment to "social-first" architecture. The firm has delivered over 500 social housing units for the boroughs of Hackney, Tower Hamlets, and Southwark, with budgets ranging from £2 million to £35 million per project—projects where architectural quality is never sacrificed to public sector budget constraints. The Tayport Close project (Hackney) was notably nominated for the RIBA Stirling Prize in 2019. It is this standard that Marie Cardwell de Bryas is transferring to France, where the built heritage of the Cévennes—a UNESCO World Heritage site since 2011—and the Camargue farmhouses require a subtle dialogue between contemporary intervention and respect for local vernacular. "Quality architecture should not be reserved for wealthy private clients," she summarizes. "This has always been at the heart of Stephen Taylor Architects' DNA."
At a time when the French architecture sector—which generates €8.7 billion in annual turnover according to INSEE—seeks to reconcile the energy transition (2050 carbon neutrality goal), urban densification, and heritage preservation, the hybrid model embodied by Marie Cardwell de Bryas charts a unique course. A Franco-British office, dual professional registration, active editorial work with the OECD, commitment to social housing, and roots in rural areas with strong identities: the opening of the French branch of Stephen Taylor Architects is not simply a geographical expansion of a London agency. It is proof that demanding, socially committed, and intellectually rigorous architecture can be exported, take root, and thrive in new territories. The fifteen ongoing projects between Paris, the Cévennes, and the Camargue are just the beginning. (
