The Zando Central Market redevelopment in Kinshasa, Democratic Republic of the Congo, designed by THINK TANK architecture, has been selected among the 20 winning projects of the 2025 Holcim Foundation Awards in the Middle East and Africa region. Originally designed for 3,500 traders and now accommodating more than 20,000 vendors, the market has long operated under conditions of severe overcrowding and infrastructural strain. The project stands out for its large-scale public ambition, its reliance on locally available materials and skills, and its capacity to accommodate both formal and informal economies within a rapidly transforming urban context.




By shifting rotation away from traditional hinges and distributing weight vertically, pivot doors were developed to address a specific architectural challenge: how to move large, heavy door panels with precision, durability, and minimal visual interference. These systems allow doors to grow significantly in scale, weight, and material ambition, often blurring the line between door, wall, and architectural surface. Over time, this technical innovation has expanded the role of doors in architecture, allowing them to operate not only as points of access, but also as spatial thresholds, compositional devices, and expressive elements within the building envelope.
Highlighting this evolution, FritsJurgens established the Best Pivot Door Contest to showcase projects where engineering precision and architectural intent converge. Founded in the Netherlands, the company is internationally recognized for its concealed pivot systems capable of supporting exceptionally large and heavy doors. These systems give architects greater freedom in scale and materiality while maintaining precision, reliability, and architectural clarity.
