What the data is
Country-level renovation cost benchmarks, derived from Eurostat's Construction Cost Index and calibrated to researched material and labour rates. Published openly as CSV under CC-BY-4.0.
What it isn't
Not a contractor quote, and not city-level pricing. Local craftsman rates, site conditions and finish choices can swing real costs by ±20%. For an exact price, request a local estimate.
