Lex Mapia gives estate agents, solicitors, and property professionals fast, consistent, professional-grade plans built from Ordnance Survey data — at every stage of a property transaction, from the first brochure to the final title plan.
Each plan is typically produced separately, with different tools, by different people. Where boundaries are drawn by hand, accuracy depends on the tool being used and the person using it. The result is inconsistency, duplication, and problems that surface when they are most costly to resolve.
Plans produced with different tools by different people look different. Across a portfolio of listings, that inconsistency is visible to clients and reflects on the quality of the firm. A professional firm's brochures should not look like they came from different companies.
Inconsistent across your portfolioWhere boundaries are drawn by hand, accuracy depends on the tool and the person using it. An approximate boundary in a brochure is not always a minor issue. It can become a significant problem when a sale reaches a solicitor and the title is checked against Land Registry data.
Geometry as accurate as your mouseBoundary issues that are visible on the map at listing stage are often not identified until a solicitor's title check, weeks into the transaction. At that point, resolving them is costly, time-consuming, and can delay or lose a sale that would otherwise have been straightforward.
Issues surface at the worst moment"The result is inconsistency, duplication of effort, and boundary issues that could have been caught at the outset — before they became expensive."
Lex Mapia produces beautiful, consistent brochure plans that reflect the quality of a professional firm. Search for a property, select the OS MasterMap boundaries, and produce a plan in minutes. The same styling, every time, across every property on your books — because the output is driven by the data, not by whoever happened to draw it that day.
Plans are not drawn by hand. They are built by selecting actual OS MasterMap geometry — the same data professional cartographers use. The boundary is precise. Not an approximation. Not dependent on a steady hand. The actual registered boundary.
Because the plan is built from OS MasterMap, it converts directly into a contract plan or Land Registry compliant title plan without redrawing. The same boundaries, used throughout the transaction. Boundary issues are visible from the outset — not discovered by a solicitor weeks into a sale when they are hardest to resolve.
Producing plans through Lex Mapia is more cost effective than commissioning a professional cartographer for every matter, while leaving that option available when a plan is genuinely complex. The saving compounds across a portfolio of listings.
The same geometry serves the brochure, the contract, and the title plan. No redrawing at each stage. No starting from scratch with a different tool. One plan, carried through the sale without additional cost or effort.
Boundary issues visible at listing stage are caught early, not discovered by a solicitor weeks into a sale. Resolving a mapping problem at the brochure stage costs very little. Resolving it mid-transaction can cost the deal.
When a plan requires more than the workspace can provide — a complex boundary, a transfer of part, a matter that needs a chartered surveyor on the ground — one click submits it directly to a qualified cartographer or chartered surveyor.
Everything they need is already in the matter. They can assess the situation, provide a quote, and return the completed plan directly into the platform. The context is captured early, which means less back-and-forth and a faster resolution — whether that saves a stalling sale or simply avoids one.
No other DIY tool offers this. Lex Mapia is the only property mapping platform with direct access to qualified professional sign-off built into the workflow.
