The Cologne office letting market failed to experience any sustained recovery in the third quarter. While many companies remain actively engaged in the search for new office space, the number of transactions actually concluded remains at a low level. The continued absence of large-scale lettings is weighing particularly heavily on market performance. At the same time, occupiers are becoming increasingly selective, with demand focused on modern, flexible and ESG-compliant space, while older stock is coming under growing pressure.
Around 31,400 sq m of office space was taken up in the third quarter of 2026, significantly below the level recorded in the same period last year. Total take-up for the first nine months of the year amounted to approximately 104,000 sq m, leaving the first quarter as the strongest quarter of the year to date.
Large Transactions Continue to Be Absent
Current developments in the Cologne office market are driven less by a lack of demand than by subdued transaction activity. While several major lettings, including those by public-sector occupiers, shaped market performance in the previous year, a comparable stimulus has yet to materialise in 2026. No lease agreement exceeding 10,000 sq m had been recorded by the end of September.
The largest transaction of the year so far remains Deutsche Bank’s lease at Dominium for approximately 7,000 sq m. Other notable lettings include MSIG Europe at KölnTurm (around 3,400 sq m), Cleary Gottlieb at Greenhub Cologne (approximately 2,500 sq m), and Katholino Service gGmbH at Josef-Lammerting-Allee (around 2,100 sq m), the latter brokered by Cushman & Wakefield. All of these transactions were completed in the first half of the year, leaving the market without significant new momentum in recent months.
At the same time, decision-making processes are becoming noticeably longer. Against a backdrop of economic uncertainty, rising costs and evolving workplace requirements, many occupiers are reviewing their real estate strategies with greater scrutiny. Location decisions are being prepared more carefully and assessed over longer timeframes.
Mina Dadgostar, Head of Office Agency Cologne at Cushman & Wakefield, commented:
“The Cologne office market is currently performing below its underlying potential. Demand fundamentally remains in place, particularly from the insurance, technology, consulting and healthcare sectors, as well as from public-sector and quasi-public institutions. Many organisations continue to actively evaluate their workplace and location strategies and are reviewing a range of occupational options.
The key challenge lies in the mismatch between occupier requirements and the available stock. Demand is concentrated on modern, ESG-compliant office space in central city locations, fringe city areas and Deutz, ideally with excellent public transport links and a high-quality working environment. Occupiers are primarily seeking contiguous floorplates that support flexible workplace concepts.
At the same time, a significant proportion of the available supply consists of older office space that no longer meets many occupiers’ expectations in terms of technical specification, sustainability or space efficiency. As a result, we are currently witnessing less of a shortage of demand and more of a challenge in matching supply with occupier requirements. Many search mandates remain active, but require considerably more time before a final decision is reached.”
Prime Rent Stable, Average Rent Slightly Lower
Prime rent remained stable in the third quarter at €33.00 per sq m per month, although this represents a slight decline compared with the same period last year. The weighted average rent fell to €20.00 per sq m per month by the end of the quarter.
This movement should be viewed in the context of the comparatively low level of leasing activity. In a market with few large-scale transactions, individual deals have a much greater influence on average rental levels than during periods of broader market activity.
Vacancy Rises but Remains Moderate by National Standards
The vacancy rate increased to 6.0% at the end of the third quarter. Despite the rise, Cologne continues to record a comparatively low vacancy level, remaining well below those of other major German office markets such as Frankfurt, Düsseldorf and Berlin. Only Hamburg is currently operating at a similar level.
Available vacant space now totals approximately 517,500 sq m within an overall office stock of around 8.6 million sq m. The continued adoption of hybrid working models and the more critical reassessment of space requirements are prompting occupiers to reduce or consolidate existing accommodation, bringing additional supply to the market.
Development Pipeline Driven by New-Build and Refurbishment Projects
Approximately 8,500 sq m of new office space was completed during the third quarter. Since the beginning of the year, total completions have reached around 58,200 sq m.
The development pipeline continues to be shaped by major public-sector projects and extensive refurbishment schemes. Significant office developments include DÜXX in Deutz and the new LVR administrative headquarters at Ottoplatz. In addition, Friedrich und Karl in Niehl is delivering a new office quarter comprising approximately 49,500 sq m. One of the most prominent refurbishment projects remains the redevelopment of the Weltstadthaus on Schildergasse.
Outlook: Recovery Expected in the Final Quarter
Mina Dadgostar concluded:
“For the final quarter of the year, we continue to see a healthy pipeline of active requirements and ongoing negotiations, several of which are already at an advanced stage. We therefore expect transaction activity to increase compared with recent months.
Whether this translates into a meaningful market recovery will depend largely on how many of the current leasing processes can be successfully concluded before the year-end. Based on current market conditions, annual take-up of between 140,000 sq m and 150,000 sq m appears realistic. While this would leave the Cologne office market below last year's level, it would also indicate significantly stronger activity in the final quarter than we have seen recently. The market fundamentals required for a further recovery are in place. However, a return to the take-up levels achieved in previous years is likely to depend on a renewed increase in large-scale lettings and the delivery of additional modern office space capable of meeting occupiers’ increasingly demanding requirements.”
