We use software to extract, cross-reference and decode planning data that most people cannot access. You get an intelligence report — specific to your site, built by a software studio, delivered within 48 hours.
Request your report →Local planning authority portals are designed to be searched by humans, not queried by machines. Committee meeting records, officer reports, comparable decisions — publicly available in theory. Getting to them requires custom tooling, persistence, and knowing exactly where to look. That is what we have built.
Every relevant LDP designation mapped to your site — decoded into plain English, not planning jargon.
We scrape committee records and planning registers to surface relevant approvals and refusals — including ones that never appear in standard search results.
Understanding why similar applications failed is often more valuable than knowing why they succeeded. We pull apart the wording.
2–3 ranked routes with an honest assessment of viability and what each one requires to succeed.
We've built custom tooling that queries planning committee PDF archives and officer reports directly — bypassing the standard public portal that only surfaces a fraction of what's actually on record. Most planning agents use the same search you do.
Finding a comparable decision is useless if you can't read it. We decode officer report language, committee vote records and condition wording to tell you exactly what swung each decision — and what that means for your site.
A planning consultant gives you an opinion formed from experience. We give you data extracted from the specific committee decisions that govern your site.
Three real enquiry types. Details anonymised. This is the depth of intelligence you receive — presented as a working document you can take directly to an architect or planning agent.
The client owned a 4-acre rural parcel in a designated AONB and wanted to understand whether any route existed to place a permanent dwelling on the land. Standard advice had been uniformly negative. We were asked to look harder.
The client had acquired a former grain store and wanted to convert it into five commercial workspace units. Two planning agents had given conflicting advice. They needed clarity before spending money on drawings.
A 2019 refusal existed on record. Their solicitor advised walking away. They asked us to look at whether that refusal was truly final — or whether someone had just applied it badly.
You know the cost before you commit. Every report is produced by Sierra21 Software Studio using custom tooling built to extract planning intelligence that standard portals cannot surface.
The full decode — policy layer, comparable decisions, strategy options and what to avoid. A professional written report you can take directly to an architect or planning agent.
