Before sketching anything, you need the parcel's zoning: land-use decision, coverage and FAR, height limit, setbacks and building order. This guide shows where that information lives, how to read it, and how RONCHAMP automates the lookup where official sources exist.
Where the information lives
- Municipal city guides (Netcad/KEOS based): many district municipalities publish the in-force plan per parcel — zone, emsal, building order.'
- e-Devlet parcel services: ownership and cadastral geometry; zoning depth varies.
- The binding document: the official zoning status certificate issued by the municipality. Everything else is preliminary.
Reading the plan notes
The numbers rarely stand alone. Plan notes can add emsal exemptions, roof rules, ground-floor commercial requirements or special conditions. When a note conflicts with the general regulation, the note usually wins — read them before trusting any single ratio.
What RONCHAMP automates
Where an official source publishes parcel-level zoning, RONCHAMP reads it directly, in 21 countries: Austria, Belgium, Bulgaria, Croatia, Czechia, Estonia, Finland, France, Germany, Israel, Italy, Lithuania, Luxembourg, Netherlands, Poland, Slovakia, Slovenia, Spain, Türkiye, United Kingdom, and United States. The values arrive with their source and vintage attached. Where no official source exists, the field is marked UNKNOWN — we never fabricate a number. The feasibility study (setbacks, buildable mass, floor plans) then runs on top of those values in seconds.
Honest boundary: RONCHAMP outputs are preliminary design support. The binding zoning status is the certificate issued by the municipality.
