Construction costs replace financing as Germany's housing bottleneck

Germany's construction cost problem has entered a new and sharper phase. Prices for the construction of new conventional residential buildings rose by 5% in May 2026 compared with the same month last year, according to the Federal Statistical Office — the largest annual increase since August 2023. That represents a marked acceleration from February, when annual construction cost inflation stood at 3.3%.

The timing could hardly be worse. Germany's housing market has been showing tentative signs of stabilising after the severe correction triggered by the interest-rate shock of 2022 and 2023. Yet just as financing conditions begin to improve, construction costs are once again becoming a major obstacle to new development. The industry's problem is no longer simply the cost of borrowing. It is increasingly the cost of building.
