Eiffage – Place de l’Agora

To enhance the attractiveness of its busiest commercial area, the city launched the construction of a new shopping mall and a series of outdoor installations. A key element of the masterplan was a state‑of‑the‑art circular LED screen that would wrap the upper section of an old brick chimney standing a few metres from the mall’s main entrance. The screen is used to broadcast promotional videos for the mall’s retailers as well as city announcements, seasonal greetings and event footage—turning the chimney into a powerful communication beacon that drives footfall and sales. Recommended by Coup d’Éclat and with Eiffage winning the public tender, StreetCo’ was tasked with finalising the technical design and delivering the installation.

– Dimensions. The brief called for a 6 m‑diameter × 1.92 m‑high cylindrical display installed on a chimney measuring roughly 6 m in height and 5.5 m in diameter.

– Structure. We engineered a bespoke steel frame whose segmented rings can be individually adjusted to compensate for the chimney’s irregular, slightly oval geometry.

– LED technology. For durability and resistance to vandalism we selected the LST10 outdoor series, coupled with a Novastar VX400 controller that gives the operator extensive content‑management options (layering, splitting, real‑time adjustments, etc.).

– Project timeline: 9 months (5 months manufacturing, 2 months transport, 2 months on‑site assembly and commissioning).
