The UK government is advancing a partnership with Google DeepMind, Google Cloud, and Faculty to deploy an artificial intelligence planning prototype designed to accelerate housing delivery and support the national target of 1.5 million new homes by 2029. The initiative addresses critical bottlenecks within local planning authorities, where manual processing of dense paperwork and administrative backlogs hinder progress. Householder applications, including loft conversions and extensions, comprise nearly 70% of total planning requests, creating a significant workload that delays decisions. The new prototype, developed using the Gemini model, aims to cut application processing times by 50%. By automating data extraction, cross-referencing policy documents, and analyzing historical files, the tool streamlines routine tasks, enabling planning officers to focus on complex applications requiring substantive judgment. The technology co-development involves collaboration with local councils in Barnet, Dorset, and Camden to ensure the system addresses the specific operational challenges faced by planning staff. This effort builds upon the successful deployment of Extract, an earlier Incubator for AI tool created to digitize legacy planning records. The prototype functions as an assistive instrument, maintaining strict human oversight; planning officers remain the final decision-makers, retaining full authority to approve or reject applications. The system provides a comprehensive audit trail and chain of thought, requiring officers to review and edit all generated reasoning to ensure accountability. Following initial trials, the government intends to make the AI planning assistant available to all councils across the UK by 2027.
