The Housing Delivery Symbiosis: How London's Sectors Build Together

London's housing delivery depends on the simultaneous functioning of four distinct sectors: private developers, Registered Providers, local authorities, and community-led organisations. This report examines three questions using Planning London Datahub data: What share of the residential pipeline includes a named Registered Provider?

Architecture Practice Landscape: London's 2,500 Practices

A systematic analysis of how 2,547 RIBA-chartered practices in Greater London present themselves publicly — their stated specialisms, client positioning, sustainability claims, and market orientation — cross-referenced against their actual planning track record in the PLD dataset.
