Germany's housing sector recorded a sharp downturn in 2025, with the number of completed housing units falling to its lowest point in over a decade. According to the Federal Statistical Office (Statistisches Bundesamt) in Wiesbaden, only 206,600 housing units were completed throughout the year. This represents an 18% decline compared to the previous year and marks the second consecutive year of significant losses. The last time Germany saw fewer completions was in 2012, when 200,500 units were finished.
Germany's housing construction has experienced dramatic swings over the past two decades. The sector hit rock bottom in 2009 with just 159,000 completions. From there, the numbers climbed steadily, peaking at 306,400 units in 2020. However, the recovery was short-lived. Since 2021, annual completions have consistently stayed below the 300,000 mark, and the downward slide has only accelerated through 2025.
The downturn was not limited to one segment of the market. In newly constructed residential buildings, 172,600 units were completed, a drop of 20% or 43,300 fewer units than the year before. Single-family homes, typically built by private individuals, saw a steep 23.3% decline, with only 41,800 completed.
Units in two-family houses fell by 21.4% to 13,800. Multi-family buildings, the largest category by volume, recorded 109,800 new units, down 18.9% or 25,500 fewer than in 2024. Even residential homes such as dormitories were not spared, with completions dropping 15.1% to 7,200 units.
Non-residential buildings contributed just 3,300 new housing units in 2025, a 31.8% decline. These include units like caretaker apartments in school buildings or residential spaces above commercial areas in city centres. Renovation and conversion projects in existing buildings also slowed down, producing 30,700 units, a modest but notable 1.8% decrease.
One of the most concerning trends is the growing gap between receiving a building permit and completing a project. For housing units finished in 2025, the average construction timeline was 27 months, up from 26 months in 2024 and just 20 months in 2020. This seven-month increase over five years reflects deeper structural challenges facing Germany's construction industry.
In a troubling sign for the sector, 35,700 building permits expired in 2025 without being used, the highest figure since 2002. This represents a roughly 25% increase over 2024, when 29,000 permits expired, and is nearly 50% higher than in 2022 and 2023. These are projects that were approved but never materialised, suggesting that rising costs, financing challenges, or other obstacles prevented developers and individuals from following through.
Despite the drop in completions, building permits issued in 2025 actually rose by 10.6% to 238,100, a number higher than the total completions for the year. As a result, the construction backlog remained largely unchanged. At the end of 2025, approximately 760,700 approved housing units were still awaiting completion, nearly identical to the 759,700 recorded at the end of 2024. Of these, 307,200 units were already under construction, with 158,600 having reached the shell construction stage.
Federal Minister Hubertz expressed confidence in the government's approach, telling the Rheinische Post that current policies focused on investment, faster processes, and reducing construction costs are already showing results. She pointed to upcoming measures including accelerated planning and approval procedures as well as funding programmes that would help push completion numbers back up, even under difficult conditions.
The Housing Construction Alliance, a coalition of construction associations, the building workers' union, and the tenants' association, took a far more pessimistic view. The alliance described Germany as being trapped in a deep structural housing construction crisis and predicted that completions in the current year could fall below 200,000 units. It called for faster implementation of simplified building regulations and more attractive government subsidies.
The GdW, the federal association of German housing and real estate companies, warned that hundreds of thousands of approved housing units are not being built due to high costs, complicated regulations, and a lack of planning certainty. GdW President Axel Gedaschko said that people are already feeling the impact of the construction crisis through rising rents and a shortage of available housing. He called on politicians to deliver a decisive push for affordable housing.
The data paints a clear picture of a housing sector under significant pressure. Fewer units are being completed, timelines are getting longer, permits are going unused, and a massive backlog continues to grow. With demand for affordable housing remaining high across German cities, the widening gap between what is needed and what is being delivered presents one of the country's most pressing economic and social challenges.
