Bratislava's total office stock stands at 1.75 million sqm, with A+ grade space accounting for 22%, grade A for 38% and grade B for the remaining 40%. No new office buildings were completed in the second quarter of 2026, though two projects are expected to be delivered in Q3: Dunaj (8,000 sqm) and Ganz House (9,400 sqm). The Bratislava Research Forum, whose members are CBRE, Colliers International, Cushman & Wakefield and iO Partners, also notes that a methodological change introduced in Q4 2025 now limits the definition of a green building to those whose certifications reflect actual operational performance, focusing on building management, resource efficiency and long-term sustainability.
Under the updated methodology, Bratislava currently has 712,670 sqm of certified green or operationally sustainable office space, representing 41% of total stock. This figure is approximately 140,000 sqm lower than under the previous methodology. Around 200,000 sqm is currently under assessment and could significantly increase the certified total in the near future. The city has 39 office buildings holding either BREEAM or LEED certification, split 54% and 46% respectively. Digital Park II+III and Einpark Offices hold the highest LEED Platinum rating, with Einpark Offices also being the only building in Bratislava with LEED Zero Carbon certification. Pribinova 40 received a BREEAM Outstanding rating during Q2 2026.
Leasing activity in Q2 2026 reached 52,931 sqm. Renegotiations dominated at 53% of total volume, followed by new leases at 38%, expansions at 5% and pre-leases at 4%. Transactions in grade A and A+ buildings accounted for 63% of total volume, with grade B buildings making up approximately 37%. The manufacturing sector led demand with a 23% share, followed by financial services at 20% and professional services at 15%. The largest single transaction was a renegotiation of 5,336 sqm at Šturova 4 in the manufacturing sector. In total, 15 transactions exceeded 1,000 sqm, of which 66% were renegotiations.
The overall office vacancy rate stands at 13.42%, equivalent to 235,500 sqm of the total 1.75 million sqm stock. Vacancy remained broadly unchanged quarter on quarter but fell by 0.99 percentage points year on year, primarily due to limited new supply. By grade, vacancy in A+ buildings is 8.86%, in grade A buildings 16.72% and in grade B buildings 12.79%. The CBD submarket holds the largest share of total stock at 36%, followed by Outer City at 20% and City Centre at 19%.
Prime rents rose quarter on quarter to €22.00 per sqm per month. Growth in prime rents has been under way since 2022, driven by above-average demand alongside rising construction material and labour costs. Further increases are anticipated by the end of the year, given the limited supply of A+ space in central locations and a low overall volume of space under construction.
