The historic Old War Office (OWO), a Grade II* listed neo-Baroque landmark in central London, has undergone a remarkable transformation. Renson’s louvres have been seamlessly incorporated into the building’s façade, offering discreet yet effective airflow management.

The OWO is example of adaptive reuse in architecture, where heritage meets modern sophistication.

A pivotal element was the integration of Renson’s innovative 450 and 480 louvres. These high-performance ventilation solutions played a crucial role in enhancing indoor air quality, energy efficiency, and aesthetic harmony, all while preserving the building’s architectural integrity.

Balancing heritage with innovation

Transforming a historic structure into a contemporary space demands a delicate balance between conservation and innovation. Renson’s louvres were incorporated into the façade, providing discreet and effective airflow management.

This ensured optimal indoor climate control without compromising the grandeur of the original design. By reducing reliance on mechanical ventilation systems, the louvres contributed to lower energy consumption-aligning with modern sustainability standards and demonstrating how heritage buildings can be future-proofed without sacrificing their legacy.
