Old Brewery, Bristol – Class A Fire-Rated Paving System

Wallbarn supplied a fire-rated paving system for the rooftop areas of the Old Brewery redevelopment in South Bristol. Spanning approximately 400 square metres across five distinct zones, the project required a flexible solution capable of supporting both 600x400 mm and 400x400 mm x 50 mm paving slabs, while meeting current Class A fire performance requirements.

The system comprised MetalPad Ex adjustable pedestals, I-Plus aluminium joists, and Wallbarn’s paving headpieces. Due to the variation in slab dimensions and deck heights, spreader plates were included to provide additional stability and to protect the waterproofing membrane across areas with sensitive detailing. The system was selected for its full non-combustibility, in line with building regulations for multi-unit residential developments.

Wallbarn was involved from early engagement through to final installation. After an initial specification meeting in mid-2024, layout drawings and material take-offs were issued. A design update later that year required revised quotations and structural recalculations. The system layout was refined through several virtual consultations with contractor Afan Group, ensuring alignment with changes to deck heights and rail configurations across the five roof zones.

Following delivery, Wallbarn attended site alongside the contractor to assess restricted installation zones. These areas required modifications to standard build-ups, which were resolved with adjusted rail spans and revised pedestal placement. The installation was completed to programme, providing a compliant and robust paving solution for this complex urban regeneration site.

Located on the former Ashton Gate Brewery site, the Old Brewery development brings together new-build housing and commercial spaces, with rooftop hard landscaping designed to perform long-term under challenging site and access conditions.
