Who owns a piece of land is public information and practically very hard to use. The answer is usually a company, that company is often owned by another, and the boundary you care about is a shape on a map rather than a row in a table. This puts the three together, so a search on a street returns the parcels, the registered owner, and where that owner is a company, its officers, controllers and charges. It is the one build here deliberately not on the house stack, because serving national map data and loading bulk registry files breaks the usual model rather than bending it, and an exception has to name the constraint it hits before it is allowed to be one.
What Was Delivered
The four areas this practice works in, and what this engagement covered in each. Two of the four were in scope here, and the rest are listed so the shape of the job is visible rather than implied.
- Offer and pricingNot in scope
- What the business sells, who to, at what price, and whether it is worth doing at all.
- Systems and software
- Search by postcode, street, council area or owner, boundaries drawn on a map, and corporate owners traced through to the people behind them. Deliberately not on the house stack, because serving national map data and loading bulk registry files breaks the usual model rather than bending it.
- Customers and demand
- Origination. The output is not a title number, it is a name somebody can approach.
- Structure and complianceNot in scope
- Entity, records, insurance, and what the rules allow a business to claim. The things that bite later rather than today.
