Our Story

Established by Italian architect Chantal Martinelli and her French husband Julien Desormeaux, Mad Atelier is a little pocket of Mediterranean style transported to London’s East End.


Opened in late 2017 on Lower Clapton Road, the store specialises in hand-selected playful pieces by contemporary designers, as well as vintage finds picked up by Chantal and Julien from galleries in Milan, Paris and Barcelona. The mix is constantly evolving as the duo discover new workshops, studios and craftspeople to collaborate with, often on exclusive pieces.


A reflection of Chantal and Julien’s instincts rather than current trends, Mad Atelier’s vibe is a melting pot of Southern European and Northern African aesthetics – much like the Mediterranean itself. This sun-kissed oasis is also home of Chantal’s architecture and design studio, established in 2013, which has excelled in giving characterful and historic buildings a contemporary reimagining. Mad Atelier’s home, for example, is a former East London boozer that had been empty for 12 years before the couple gave it a new lease of life.

Mad Architecture


MAD Martinelli Architecture & Design is a process-led architectural design studio that delivers inventive, individual and functional architectural solutions.

Founded in 2013 by Chantal Martinelli in London, this young architecture and design studio thoroughly enjoys the challenge of a wide range of projects varying in scale, complexity and interventional capacities.

Through exploring new materials, techniques, typologies and hybrid systems, we strive for excellence while the interests and services of our practice grow. We work in collaboration with experts in the fields of interior design, bespoke furnishings and restoration in order to bring skilfully developed tailored results to our clients.

The M.A.D. Team with our varying areas of expertise and passion fuse together to form a laboratory of architectural ideas aimed at improving the quality of lives through architectural interventions, harmoniously merging interior with exterior spaces and taking part in the dialogue about the future of urban development and sustainable living. Our current projects include new residential buildings, home extensions and refurbishments, gastronomic interiors, a boutique hotel and a mixed-use development scheme. Additionally, we also offer consulting services in Urban Planning and Design.


Chantal is the founder of M.A.D and the creative force behind the studio’s signature style.She studied Architecture at the Ecole Superieure d’Architecture de Versailles (France) and at La Sapienza in Rome (Italy), where she received her Masters Degree in Architecture. After attaining some practical experience, she enrolled in further studies at the Architectural Association in London where she received her Postgraduate in Housing & Urbanism. Beginning her practicing career at Foster+Partners, she went on to work for other internationally renowned architectural firms such as BDP and Arup Associates, before utilising this broad range of experiences to take the leap and start her own architectural studio. Chantal Martinelli is an ARB registered architect in Italy and the UK. She is also is a Chartered Member of the Royal Institute of British Architects.


Alberto studied at Politecnico di Milano (Italy) where he graduated in ‘Architecture City and Landscape. While still a student, he collaborated with Sinergie Lupi Engeneering Group SRL and Daniela Sormani & Co carrying out projects in Italy and abroad (mainly in Kenya). Soon after receiving his Postgraduate in Architecture, he moved to London to continue his architectural career at M.A.D. as Part III qualified Architect. His passions are landscape design, the exterior spaces and gardening.
