The report ’ what it checks
Thirteen registers, one page.
Designations
Thirteen registers — conservation area, listed status, flood zone, Article 4 and more — each recorded, clear, or honestly unreachable.
Decisions
Every planning decision within 300 m, with the approval rate of the ones that were decided.
The building
The mapped footprint, the neighbours that abut it, and a measured height from LIDAR.
Sources
Every fact carries its register, its date and a link. Nothing here is a verdict.
How it works ’ three steps
From an address to the estimate.
An address
Any existing home in Greater London. Type it, pick it from the list, and HomeFinder locates the building on the map.
The planning checks
Thirteen registers and every nearby decision, checked live — each finding with its source and date.
The estimate
An automated, early-stage read of what the site could take: the house in 3D, an extension within permitted development, a rough value uplift.
Information and early-stage estimates only — not professional advice. Always confirm with a qualified architect and a builder before making any decisions.
