Archimétro
Youssef Joundy
I am Marlice Alfera, an architect-engineer with a passion for small-scale projects in dense urban areas, as well as for transit networks - from stations to trains.
During my studies at ENSA La Villette, I joined a studio led by Jim Njoo focusing on the Grand Paris Express project currently under construction in the Paris region. This experience immediately resonated with my own relationship to transit. As a banlieusarde, I have spent countless hours navigating the regional transit system. In the Paris region and its suburbs, this extensive but often criticized network is a core element of identity and has shaped my relationship to the city. I like to say I am an “RER C girl”—in other words, from the south of Paris.
A year later, I went to Japan for an exchange year and discovered Tokyo’s vast metro network, and the way it shapes the city through its functionality, architecture, and density. The book Made in Tokyo, edited by my professor and internship supervisor Yoshiharu Tsukamoto, sheds light on this layering of functions within the city. I often spent my free weekends riding the metro, exploring new areas and experiencing different lines.
Back in Paris, I decided to further develop my focus on small-scale projects. In 2021, my apartment renovation was featured in the YouTube program Never Too Small. I then founded my practice, working on renovations and small extensions while joining the Échelle Un incubator.
In 2024, the opening of new transit projects in the Paris region rekindled my interest, and I began documenting my explorations of new stations and trains on social media. As this work gained attention from both peers and professionals, Youssef Joundy, a transit consultant, and I decided to organize guided tours addressing transit networks, architecture, and urban planning.
Today, Archimétro brings together around a dozen active members and has organized more than 30 tours for a wide range of audiences, including students and professionals.
Exploring the city through public transit, observing its transformation
Archimétro is an association founded in 2024 by Marlice Alfera, a graduate architect-engineer, and Youssef Joundy, an engineer specialized in transit systems. It focuses on walks and guided tours through newly opened public transit projects in the Paris region.
From the extension of Line 14 opened before the Olympics to the upcoming Grand Paris Express network, we engage people in exploring transit systems, their design, and their connection to the city. Our work lies at the intersection of transit engineering and technology, architecture, mobility, urban planning, and, of course, knowledge sharing. We explore the development of cities around transit from both historical and contemporary perspectives, as well as the future of mobility in urban areas, at a time when many cities—especially in Europe—are turning away from car-centric urban planning. During our tours, we welcome a wide range of audiences, from senior living in Greater Paris to school students.
The association also organizes debates and talks on these topics, and carry out outreach work on social media focusing on public transport, rail systems, and architecture.
Our ambition is to shed light on the political, technical, and architectural choices surrounding public transport, to bring together a European community of public transport and architecture advocates, and to help guide policy decisions toward more sustainable mobility.
