Brownfield Passports: Smarter Urban Growth Through Brownfield Redevelopment

Brownfield redevelopment through the Brownfield Passports reform presents a forward-thinking solution to addressing the challenges of growth. It offers a structured approach to transforming underused or derelict sites into vibrant spaces. By explicitly prioritising brownfield sites for redevelopment, these proposals align with the dual goals of urban densification and sustainable growth. However, their potential hinges on balancing streamlined planning processes with local considerations.

Simplifying Redevelopment on Brownfield Sites Through Planning Certainty

At their core, Brownfield Passports aim to simplify planning for urban redevelopment on brownfield sites by establishing clear parameters for what constitutes acceptable development. This clarity reduces uncertainty and risk for developers, encouraging investment in urban areas. As currently proposed, the passport system would incorporate elements like design codes, density guidelines and area-based permissions to make the process more predictable.

Supporting Brownfield Redevelopment With a ‘Yes in Principle’ Approach

Crucially, the framework aims to shift the default planning stance to a "yes" for suitable brownfield redevelopment projects - conditional on meeting specified criteria such as flood risk mitigation or alignment with local design standards​​​. This affirmative stance is designed to accelerate the delivery of much-needed homes and urban improvements.

Tackling the Barriers to Effective Brownfield Redevelopment

Despite the policy’s appeal, brownfield redevelopment often faces practical obstacles. High remediation costs, fragmented land ownership and infrastructure deficits can all hinder progress.  For Brownfield Passports to succeed, supportive measures such as targeted funding, tax incentives or public-private partnerships will be essential. Without them, planning reform alone may fail to unlock the full potential of urban brownfield sites.

Aligning National Ambitions With Local Urban Identity

 While national policy can set broad expectations, successful urban redevelopment must reflect local character and capacity. Tools like design codes and Local Development Orders (LDOs) can help align redevelopment with community values,  ensuring that new schemes contribute meaningfully to neighbourhood identity and function.

Laying the Groundwork for Wider Planning Reform

Some argue that Brownfield Passports could pave the way for broader zoning reforms. Unlike the UK’s discretionary planning system, zoning establishes clear rules for specific areas, reducing ambiguity and resistance to development. International examples, like upzoning in Auckland, demonstrate how zoning can effectively increase urban redevelopment while minimising backlash​​.

Unlocking the Full Potential of Urban Redevelopment on Brownfield Sites

Brownfield Passports are a promising mechanism to optimise urban land use and address housing shortages. However, their success will depend on a combination of financial backing, technical support and community engagement. If implemented thoughtfully, they could transform derelict spaces into thriving urban hubs, fostering economic growth and sustainability. The time to act is now, turning dormant urban assets into drivers of development.
