The site presented a combination of heritage and environmental constraints. Structurally, the retained buildings required careful adaptation to accommodate modern commercial use while preserving historic fabric. Environmentally, the site had no formal drainage system, with surface water historically dispersing via overland flow, ponds and informal infiltration. Variable ground conditions—including areas of clay restricting drainage—alongside proximity to the River Lea and groundwater sensitivity, required a robust assessment of flood risk and surface water management in line with current planning policy.
