This calculator does not establish legal buildability. Building footprint is distinguished from total floor area; actual planning regulations, setbacks and height limits must be verified for the specific plot with the municipality.

Formulas: land = plot × €/m² · tax = land × tax% · max floor area = plot × ratio × floors · construction = house area × €/m² · fees = construction × fee% · contingency = % of subtotal.
