The Regional Research Forum, a consortium of CBRE, Colliers, Cushman & Wakefield, iO Partners, Knight Frank, and Savills, has released office market data for Brno and Ostrava for the first half of 2025. The data offers a transparent overview of regional trends, supply, vacancy rates, and rental levels. In Brno, one new office building—Titanium Skylight X, developed by JRA Estate—was completed in the first half of the year, adding 10,900 sqm to the city’s stock. This brings Brno’s total modern office inventory to 704,900 sqm, with 73% classified as Class A space. Office construction continues with ten projects underway totaling 103,100 sqm, including major developments such as Dornych (27,600 sqm), Ponávka A4 (16,800 sqm), and Cerit III (10,800 sqm), the latter scheduled for completion in the second half of 2025. Tenant demand in Brno was led by the energy sector, which contributed the most significant leasing activity. The largest transaction was a pre-lease of 10,500 sqm in Nová Zbrojovka D4 by an energy company, followed by deals involving Sudop Real and Abugo. The vacancy rate rose to 12.7%, up 1.1 percentage points year-on-year. Prime headline rents increased slightly to between €17 and €18 per sqm per month. In Ostrava, modern office stock stood at 245,700 sqm at the end of H1 2025. No new completions were recorded, and only one project—the Václav multifunctional building (3,000 sqm)—is under construction, with completion expected in 2027. Leasing activity was led by Satum Czech’s new lease of 1,900 sqm in IQ Ostrava. Other deals involved financial and technology sector companies. The vacancy rate declined to 10.7%, a drop of 1.1 percentage points year-on-year. Rents remained stable at €14.00 to €14.50 per sqm per month. Overall, Brno continues to demonstrate strong development activity relative to its market size, driven by a qualified labor force and demand for modern space. In contrast, Ostrava’s market remains stable but with limited new supply in the pipeline.
