Britain has a housing problem, and a paperwork problem. The UK is working to build 1.5 million new homes by 2029, but local planning authorities are often slowed down by dense paperwork and administrative backlogs. Now, Google DeepMind and the UK government are betting that AI can cut through the backlog -- literally halving the time it takes to approve a loft conversion or home extension.
The Ministry of Housing, Communities and Local Government (MHCLG) has launched an AI-powered prototype called Augmented Planning Decisions (APD), built in collaboration with Google DeepMind, Google Cloud, and UK AI firm Faculty. MHCLG is funding APD with an £8.2 million contract with Google Cloud, Google DeepMind and delivery partner Faculty. The goal is straightforward: get planning officers out of the PDF mines and back to doing actual planning work.
Why planning is the bottleneck
Roughly 350,000 planning applications land on council desks every year. Nearly 70% of those are householder applications -- the kind covering extensions, loft conversions, and garden walls. That's about 245,000 applications annually that follow largely predictable patterns, involve standardized documentation, and still take an average of around eight weeks to process.
For a typical new planning application, officers spend hours cross-referencing policy documents, historical files and PDFs. This manual process creates a major bottleneck. The irony is that most of these cases are routine -- but the sheer volume means complex, high-impact housing projects end up waiting in the same queue.
