The site at Maladière in Lausanne possesses a rich yet often overlooked history. Initially, it featured a bridge spanning the Flon River, which was later transformed into a road junction following the river’s canalisation. Today, it stands as a vast roundabout, a vestige of the 1964 national exhibition, constructed to showcase infrastructure during a time when automobiles epitomised innovation. However, its central island has become an urban void, primarily due to limited pedestrian access points and the constant encirclement of heavy traffic. Drawing on the thesis’s exploration of nostalgia in architecture, which posits it as a method for formulating a historical continuity by preserving cultural heritage and identity through its embedded stories, the project seeks to reimagine the space. The programme evolved by interpreting the site’s historical and current narratives while envisioning its future potential(s). This approach resulted in the incorporation of a new layer of infrastructure, embracing the roundabout’s circular form to reconnect with its surroundings. The structure serves as a stage, a backdrop for the central island, designed to welcome and engage the public. It invites the visitors to traverse and interact with the space, encouraging a rediscovery of urban connections. The design aims to preserve the existing sense of voidness, transforming it into a valuable spatial quality in today's urban context, offering a serene and contemplative environment.
