Factory Expansions & Retrofit Projects: Why the Future of Food Manufacturing Is Being Built on Existing Sites 

26 June 2025
Tim Dixon, Managing Director

As demand for safe, sustainable, and flexible food production rises, factory expansions and retrofit projects are becoming a defining trend in the construction of food facilities. 

Rather than building from scratch, more food manufacturers are choosing to extend, repurpose, or redevelop existing sites. Whether it’s modernising a legacy facility, scaling up live operations, or transforming an old logistics warehouse into a food-grade site — smart reuse is driving the sector forward. 

Remodelling Live Sites: A High-Stakes Balancing Act 

One of the biggest challenges in food factory construction today is the expansion or remodelling of live production sites. These projects are complex, but increasingly common as manufacturers aim to: 

  • Meet surging consumer demand 
  • Launch new product lines 
  • Comply with updated regulatory standards
  • Improve energy efficiency without halting production 

Key considerations for live-site construction include: 

  • 🔁 Phased delivery: Breaking projects into manageable stages to maintain output and safety. 
  • 🧼 Food-safe containment: Using temporary partitions, negative air pressure zones, and strict hygiene protocols to isolate works and prevent contamination. 
  • ⏱️ Minimal disruption: Careful coordination with factory ops teams to avoid downtime and protect product integrity. 
  • 👷 Specialist contractor experience: It’s not enough to be a good builder — teams must understand HACCP, allergen control, and clean design protocols. 

Done well, a live-site project delivers a modern, compliant, and future-ready facility without pausing the production line — turning risk into resilience. 

Brownfield Redevelopment: From Redundant Sites to Food-Grade Facilities 

With greenfield land increasingly scarce or slow to approve, the industry is turning to brownfield sites — former industrial, retail, or logistics units — and reimagining them as state-of-the-art food factories. 

This approach offers huge opportunity, but comes with unique challenges: 

  • 🔍 Structural assessments: Understanding floor loading, ceiling heights, and services compatibility. 
  • 🚰 Upgrading utilities: Many old sites lack the water, drainage, or power capacity needed for modern food production. 
  • 🧱 Zoning and flow redesign: Adapting open-plan warehouses into food-safe, logically zoned environments (raw to finished product). 
  • 🌱 ESG alignment: Repurposing old buildings supports circular economy goals, reduces embedded carbon, and helps meet Net Zero targets. 

For food manufacturers looking to move quickly, brownfield redevelopment offers a faster path to operational capacity — often in prime locations with existing transport links and planning history. 

Why It Matters 

Whether expanding an existing facility or transforming a disused site, retrofit and redevelopment projects allow food producers to: 

  • Accelerate capacity increases 
  • Extend asset life 
  • Meet modern compliance and sustainability standards 
  • Maximise ROI on underused space 

In a fast-moving, margin-sensitive industry, speed, flexibility, and hygiene compliance are not just priorities — they’re strategic advantages.
