Sources
Behind every line, an official source.
No data is fabricated. The public bases of the French State are cross-checked address by address, dated, and presented with their source visible. Every figure carries its year.
— Method
Three commitments
Our reading of an address rests on three principles.
- Official sources and dates, everywhere. No orphan figure. Every datum carries its origin and its year.
- Neighbourhood-scale reading. Communal sources are too vague. Whenever the data allows, we go as close as possible to the chosen address.
- Updates at a known frequency. Each pipeline states its cadence. No freshness promise without proof.
— About
Why this work.
NextToYourPlace was born from a simple observation: the information exists, but no one had brought it together address by address, on behalf of the person signing. Too many life decisions are made on a fifteen-minute viewing, leaving aside data that is public, free and official.
That is what this site does. Not to promise the perfect home. To show what the listing does not say, before the signature leaves.
The rest is yours.
