Brno
· Svatopetrská D became the only office project completed in Brno during H1 2026
· Development activity resumed with the start of construction on BRIXX Brno
· A total of 87,600 sq m of modern office space was under construction at the end of H1 2026
· Manufacturing companies generated the strongest occupier demand, ahead of the technology sector

“Overall, the main regional office markets of Brno and Ostrava continue to benefit from an established occupier base, composed of a healthy mix of local and international firms, and now a growing flex market. While vacancy rates are at elevated levels compared with Prague, these cities offer interesting opportunities for companies looking to expand and upgrade their workspaces in an era of higher office attendance rates,” says Simon Orr, Director, Office Leasing at CBRE.

One office scheme was added to Brno’s office inventory during the first half of 2026, with the completion of Svatopetrská D

(1,400 sq m) in Q2 2026. As of the end of H1 2026, Brno’s modern office stock reached 717,450 sq m. Class A properties represented 73% of the stock, while Class B buildings accounted for the remaining 27%.

(10,460 sq m).
Brno Office Leasing/Transactions
Leasing activity in Brno during the first half of 2026 reflected a relatively diversified demand structure. Manufacturing companies were the most active occupiers, confirming the sector's continued importance for the local economy and office market. Technology (IT) firms also remained a key source of demand, while financial services companies also contributed to overall market activity.
Some of the largest transactions included the renegotiation of Siemens in Ponávka A3 (1,990 sq m), together with new leases signed by Bilfinger in Spielberk IQ C, D, E, F (1,780 sq m) and JAMF in Titanium X (Skylight X) with 1,630 sq m.
Vacancy
Despite a healthy level of leasing activity, the volume of immediately available office space remained elevated. At the end of H1 2026, Brno recorded 90,750 sq m of vacant modern office space, representing a vacancy rate of 12.65%. While this was 0.6 percentage points higher than a year ago, vacancy improved compared with the end of 2025, declining by 1.7 percentage points.
Rents
Rental levels slightly increased throughout the first half of the year. Prime headline rents in Brno increased to range between €17.50 and €18.50 per sq m per month, although premium space in the most sought-after locations may achieve higher levels.
Ostrava
· No new office buildings were delivered in Ostrava in H1 2026, while the Václav Multifunctional House remained the only project under construction
· The vacancy rate climbed to 11.4%, representing a year-on-year increase of 1.1 percentage points
· Prime headline rents held steady at €14.00–14.50 per sq m per month
Ostrava Office Supply/Stock
The Ostrava office market remained characterised by limited development activity in H1 2026. No new office buildings were delivered during the period, and the Václav Multifunctional House (3,020 sq m) continues to be the only project under construction. The scheme is expected to be completed in 2027.
As a result, Ostrava’s modern office stock remained stable at 245,700 sq m at the end of the first half of the year.
Ostrava's major office transactions
Market activity in Ostrava remained concentrated among a limited number of occupiers, reflecting the city's smaller office market size. The strongest leasing demand originated from professional services firms and companies operating in the advertising and media sector.
Some of the largest transactions recorded in H1 2026 were Renomia’s lease in Organica (1,050 sq m) and a transaction by a public-sector occupier in The Orchard Ostrava (1,030 sq m).
Vacancy
The availability of office space increased further in Ostrava during the first half of 2026. Vacant office space totalled 28,090 sq m at the end of the period, corresponding to a vacancy rate of 11.4%. This represents an increase of 1.1 percentage points year-on-year and 0.5 percentage points compared with year-end 2025.
Rents
Prime office rents in Ostrava remained stable during H1 2026, standing at €14.00-14.50 per sq m per month. The limited development pipeline and stable occupier demand contributed to an unchanged rental environment.
