Japanese-born Yukiko completed a master’s degree in environment and architecture in Nara. Contrary to prevailing national policy, she chose to specialise in the conservation of Japanese architecture and began a PhD in Tokyo. Alongside her studies, she started her career in a practice dedicated to building conservation. Two years later, she moved to France, where she obtained her HMONP certification and joined an international Japanese agency working on a project in Paris. Since 2020, Yukiko has been working with us on restoration and architectural transformation projects with significant environmental ambitions.

Giuseppe holds a Master’s degree in “Sustainable Architecture” from the Istituto Universitario di Architettura di Venezia (IUAV). He moved to Paris to continue his studies with a specialised DSA Master in Architecture and Heritage at the École Nationale Supérieure d’Architecture de Paris-Belleville. His professional career in heritage architecture has been shaped primarily by his time at three Paris-based practices: François Chatillon ACMH, Pierre-Antoine Gatier ACMH, and dd.a architects, where he currently works. These experiences have enabled him to lead major projects—including the Arc de Triomphe, Musée Carnavalet, Le Corbusier’s Molitor building, and Le Corbusier’s barge Louise-Catherine—sometimes commissioned by public authorities.

Originally from Italy, Valéria graduated in Florence. She began her career at several Italian practices, working on complex projects of varying scales and programmes. She later received a mobility grant from the Turin Order of Architects to work in France, where she eventually settled permanently. Over time, she developed particular expertise and sensitivity for projects linking the rehabilitation and transformation of existing structures with new architecture. In 2020, she specialised in a Master’s in 20th-Century Heritage Conservation and Enhancement, and shortly afterwards joined dd.a, bringing her expertise to the practice.

After earning his State Diploma in Architecture in 2017, Pierre spent several months working as a freelance architect, primarily in scenography. His interest in built heritage led him to join 2BDM architects, a practice specialising in Monuments Historiques, where he worked for four years. Following the completion of his HMONP professional accreditation, he sought to return to a more diverse architectural practice, exploring the historical and heritage dimensions of architecture while continuing to engage in the creative act at the heart of each project. He joined dd.a in 2022, bringing his sensitivity and technical expertise to the agency’s various projects.

Edith holds a Master’s degree in Transdisciplinary Design, completed in residence at the Académie du Climat (CÉSAAP). She began her training in spatial design at ENSAAMA Olivier de Serres. Driven by questions concerning the role of users in the broadest sense, she is particularly interested in integrating living systems into urban and architectural design. Her curiosity about human interaction with space has led her to develop expertise in territorial analysis at multiple scales, from individual plots to entire urban contexts. She joined dd.a A following her final-year internship, supporting projects in interior layout, furniture design, and site analysis.

After completing her degree and professional accreditation at ENSA Bretagne, Stéphanie joined two regional practices before continuing her career in Switzerland: first at Hildebrand in Zürich, then at Herzog & de Meuron in Basel. On returning to France, she re-engaged with bio- and geo-sourced materials at Atelier Serge Joly and began teaching at ENSA Marseille. While these varied experiences were enriching, they led her away from a longstanding interest in rehabilitation. She addressed this by undertaking the Diplôme de Spécialisation et d’Approfondissement in Architecture and Heritage at ENSA Paris-Belleville, which she completed in 2025. Stéphanie then joined dd.a, where she combines project expertise with a particular sensitivity to existing structures, their materiality, and their history.

After earning her State Diploma in Architecture from ENSA Paris Val-de-Seine (DEA, 2022), Nina deepened her interest in architectural and landscape heritage through the DSA in Architecture and Heritage at ENSA Paris-Belleville. There, she affirmed her commitment to architecture that is rooted and contextual, attentive to the cultural, historical, and social dimensions of existing structures. Sensitive to 20th-century heritage, she joined dd.a in March 2025 to contribute to the international competition “Quartiers de Demain,” where she develops strategies for the restoration and enhancement of heritage in service of contemporary challenges.

Martin’s combined practice of architecture and history stems from a dual education at Université Paris 1 – Panthéon-Sorbonne (M2 Research, 2019) and the École Nationale Supérieure d’Architecture Paris-Malaquais (DEA, 2022; HMONP, 2023). In addition to collaborating with dd.a since 2021, he works as a research assistant to Claudia Devaux at EPFL.
