The Greek construction industry is expected to record marginal real growth of 0.8% in 2025, supported by investment in transport and energy infrastructure and steady industrial and civil engineering activity. According to the Hellenic Statistical Authority (ELSTAT), the civil engineering production index grew by 5.1% year on year (YoY) in the first six months of 2025 and the manufacturing production index grew by 0.4% YoY in the first eight months of 2025. Growth in 2025 will be slower compared to the 3.5% expansion in 2024, due to thousands of unauthorized constructions facing legal uncertainty as the government proceeds with plans to legalize the unauthorized constructions by March 2026. Around 1.7 million property owners have already regularized minor violations, but large-scale illegal buildings (Category 5) remain unresolved. As of October 2025, an estimated 20-30% of public buildings fall into this category, hindering renovation and EU funding access.
Over the remainder of the forecast period, the Greek construction industry is expected to register an annual average growth of 3.1% from 2026 to 2029, supported by public and private sector investments in the housing, energy, and transport infrastructure projects. In September 2025, the Greek government unveiled a new infrastructure strategy aimed at driving economic growth, modernizing transport and energy networks, and strengthening its international and regional profile. Some of the ongoing developments, as part of the project include the new Kastelli Airport, Crete’s Northern Road Axis (VOAK), Thessaloniki’s Elevated Expressway, Kalamata-Rizomylos-Pylos-Methoni road, Halkida Bypass, and the Bralos-Amfissa section, along with progress on Ioannina-Kakkavia, Drama-Amfipoli, and Thessaloniki-Edessa routes.
