Polish office market faces challenges from aging building stock

The Polish commercial real estate market is facing a significant challenge regarding aging building stock. According to a June 2026 report by Colliers, mature and older buildings now account for 40% to 77% of office resources in Poland's largest markets.

In Warsaw, 64% of office space is located in buildings over 10 years old, with 28% being older than 21 years. This aging trend is impacting market performance; vacancy rates in buildings aged 11–20 years have reached 14.2% outside of central locations, while in Wrocław, the oldest category of buildings sees vacancy rates as high as 34%.

As new office space supply remains relatively low—with approximately 119,000 square meters delivered in the first half of 2026 compared to a total modern stock of 13 million square meters—competition is shifting. The struggle for tenants and buyers is increasingly occurring between existing properties of varying standards rather than between new developments.
