BROAD[BAND] architecture was founded in January 2022 by two classmates who graduated together in 2019. Sylvain and his partner are the driving force behind your projects, true allies in finding the right solutions to your questions.

The agency is passionate about renovating old buildings. Their expertise lies in preserving architectural heritage while bringing a contemporary and functional vision. These architects bring these treasures of the past back to life by transforming them into modern, sustainable spaces.


"Our respectful approach combines innovation, creativity and technical know-how to create unique environments that tell a story while meeting today's needs. Together with our experienced team, we are determined to support you in your refurbishment project, creating spaces that combine the authenticity of the past with the functionality of the present."


BROAD[BAND] architecture is particularly interested in renovation and refurbishment, and has acquired solid experience on a number of different projects: extensions to detached houses, flat renovations, the refurbishment of old farm buildings, the total overhaul of an embassy in Paris, the conversion of a disused airport terminal and the transformation of a number of commercial agencies are just some of the projects on which the agency has worked.

These architects are convinced of the power of architecture to transform ideas into tangible reality. Each building has its own character and its own potential.

Their team of architects is committed to working closely with their clients to restore and transform old buildings into modern, functional spaces, while retaining their charm and authenticity. Sylvain and his team are committed to providing clients with tailor-made solutions to meet their needs and objectives, always ensuring that the historic integrity of the buildings being restored is respected.


"Our expertise is based on a creative, functional and sustainable approach to designing spaces that meet our clients' needs and aspirations. We work closely with them to understand their objectives and create bespoke designs that reflect their identity and maximise the potential of each project. Whether for homes, offices or commercial buildings, we put our expertise to work to realise your architectural vision, combining aesthetics, functionality and sustainability."


Equipped with the latest high-performance digital tools, the agency is able to immerse you in your project using the latest virtual reality and 3D rendering technologies.

BROAD[BAND] architecture offers design and implementation services to bring your projects to fruition, especially those you haven't thought of yet!

Based near Mantes-la-Jolie in the Yvelines department, the agency mainly works in the Île-de-France and Normandy regions. However, the agency also travels throughout France and internationally, in the firm belief that architecture knows no borders.
