Intelligence for London's built environment
Stormglass is a planning intelligence platform built for architects, developers, planners, and researchers who work with London's development pipeline. We aggregate, enrich, and surface data from the Planning London Datahub so you spend less time in spreadsheets and more time understanding the city.
The platform is independently built and maintained — not a corporate product, not funded by advertising. Our interest is in making London's planning data genuinely useful to the people who shape the city.
Built to close the information gap
London's planning system generates a vast amount of public data. Very little of it is easy to use. Stormglass bridges that gap.
The Planning London Datahub contains hundreds of fields per application. We parse, normalise, and present the data that actually matters — units, GIA, tenure, density, constraints.
Beyond raw applications — a curated directory of major schemes with drawings, GIS constraints, planning timelines, and delivery metrics in one place.
Borough-level delivery against London Plan targets, density mapping across the pipeline, and spatial tools that connect applications to place.
Choose how you use Stormglass
Core tools stay free. Deeper functionality — search, exports, density tools, and alerts — is available through Studio access.
Who's behind Stormglass
Stormglass is currently a lean, focused project — built by people with real experience in London's built environment, not by a generic data startup.
Architect and urban analyst with 20+ years across London's built environment. Brings together spatial design thinking and data engineering to surface patterns in the city's planning system.
Work with us
Stormglass is a small, open platform. We're interested in working with people who care about London's built environment — whether that's a joint research project, a data integration, or a long-form piece of analysis.
If you have an idea or a need, get in touch. We'd rather have a short conversation than a long form.

Custom pipeline monitoring, competitor analysis, and site search support for development teams.
Help councils understand their own pipeline data and benchmark delivery against the London Plan.
Connect Stormglass data to your own platforms — GIS systems, CRM, reporting dashboards.
