Gun Wharf Refurbishment Works

Gun Wharf Refurbishment – Project Overview (Brief)

Gun Wharf, a Grade II listed building designed by Arup Associates and completed in 1978, presents a unique challenge: modernising a historically significant structure while preserving its architectural integrity. This refurbishment project seeks to enhance several key areas, including the entrance reception, canteen, restrooms, external social spaces, and car park. A central objective is to improve the spatial relationships within the building to foster a more cohesive and efficient working environment.

The initial driver for the refurbishment was the need to address Reinforced Autoclaved Aerated Concrete (RAAC) issues, ensuring the building’s long-term structural integrity. While this issue is now being resolved, the project also presents an opportunity to deliver broader improvements.

A major focus is the proposed upgrade to mechanical and electrical (M&E) systems, aimed at enhancing the building’s atmosphere, safety, and sustainability. Remaining fluorescent lighting will be replaced with energy-efficient LED fixtures, prioritising dedicated luminaires over less effective retrofit solutions. External lighting will be redesigned and upgraded, with feature lighting introduced in the reception and canteen areas to create more welcoming and visually engaging spaces. Enhanced lighting controls will support flexible schemes and maximise energy savings.

This refurbishment represents a significant investment in Medway Council’s civic infrastructure. By tackling essential maintenance, improving energy performance, and optimising the workspace, the project will ensure Gun Wharf remains a functional, sustainable, and welcoming public building for years to come.

The attached outline drawings provide an initial indication of the proposed refurbishment approach.
