The index reports the median asking price per square metre for €1.5M+ residences, zone by zone, derived live from a deduplicated catalogue. Figures are asking prices of currently-listed residences, not completed transactions. Below is exactly how the numbers are produced — and the open licence that lets you reuse them.
Three regional feeds — Inmobalia (REST), Resales-Online and Zoddak (new-build) — plus the Muse Selection internal register, including off-market residences.
The same residence is frequently syndicated to multiple feeds. We merge and de-duplicate so each residence is counted once.
Filter to residences priced from €1.5 million. POA (price-on-request) listings are admitted only when Muse-exclusive/featured, and are excluded from €/m² maths.
Price ÷ built area, per residence. Values below €1,000/m² or above €60,000/m² are dropped as feed errors (plot mislabels, missing areas).
Group by zone; report a zone only when it has at least four priced residences. 21 zones currently qualify.
Median (headline) and average €/m², median asking price, and the min–max range — recomputed on every daily snapshot.
