Tristan Capital Partners Acquires Major Berlin Data Center Development Site from Aventos December 5, 2025 In a significant transaction underscoring the sustained investor appetite for European digital infrastructure, private equity real estate firm Tristan Capital Partners has acquired a prime data center development site in Berlin from German real estate firm Aventos. The deal highlights the strategic importance of the German capital, a market grappling with limited power and land availability amid soaring demand for cloud and AI-ready computing capacity. The sale involves a 28,400-square-meter (approximately 305,700-square-foot) plot located at Nonnendammallee 61 in Berlin's Siemensstadt district. Aventos announced the transaction this week, confirming the sale to Tristan Capital Partners' EPISO 6 opportunistic fund. While financial terms were not disclosed, the scale of the planned development is substantial. The site has the potential to host up to three three-story data center buildings with a total combined capacity of 63 megawatts, and includes provisions for an on-site electrical substation. Viktor Schulte, Development Partner at Aventos, explained the rationale behind the sale, stating, "Having reached a crucial milestone in the value chain for the development of the data center in Siemensstadt by securing the power supply contractually, the planned sale was a logical step. It allows us to concentrate our resources on other projects such as the development of the neighboring Luxwerk." The 90,000-square-meter Luxwerk business park, also under development by Aventos, is adjacent to the sold site. The transaction represents a strategic pivot for Aventos, which acquired the historical "Das Glaswerk" site from lighting company OSRAM in a 2021 sale-leaseback deal, and refocuses capital on its core development projects. For Tristan Capital Partners, a firm managing over €15 billion ($17 billion) in assets, the acquisition is a targeted deployment from its €2 billion EPISO 6 fund into a high-growth infrastructure asset class. The move signals continued confidence from institutional capital in the long-term fundamentals of the data center sector, particularly in supply-constrained major European metros like Berlin.
