STRABAG Group Acquires Olivia Star Office Tower in Gdańsk for €150 Million in One of Poland's Largest 2026 CRE Deals

GDAŃSK, Poland — July 3, 2026 — STRABAG Group, the Austrian construction and infrastructure conglomerate, has acquired Olivia Star, a 180-meter office high-rise in Gdańsk, Poland, for approximately €150 million, according to an announcement from transaction advisor Kingstone Real Estate. The deal, structured as a share deal, ranks among the largest commercial real estate transactions on the Polish market in 2026, according to Kingstone Real Estate.

The seller and project developer is Tonsa Commercial, an international real estate investor. Kingstone Real Estate exclusively sourced the asset for STRABAG Group and provided comprehensive transaction advisory, coordinating the due diligence and transaction process and supporting negotiations on the purchaser's side.

Asset Overview: Olivia Star in Gdańsk's Oliwa District

Located at 472C Grunwaldzka Street in the Oliwa district of Gdańsk, Olivia Star rises to 180 meters across 34 floors and offers approximately 40,000 square meters of premium office space. The building is the flagship tower of the Olivia Centre complex — described by Kingstone Real Estate as the largest business hub in Poland and one of the largest in Central and Eastern Europe — which comprises a total of seven buildings. The transaction covers only the Olivia Star tower; the remaining six assets will remain under Tonsa Commercial's ownership.

Beyond its office space, the building features extensive conference facilities, five restaurants, three bars, and a publicly accessible observation deck, all operating under the Olivia Star Top concept. The property's occupancy rate stands at 98 percent. Major tenants include Nordea Bank, PwC, and Olivia Star Top.

Olivia Star is the largest office building not only in the Tricity metropolitan area — encompassing Gdańsk, Gdynia, and Sopot — but across all Polish regional cities, according to Kingstone Real Estate.

Transaction Structure and Advisory Teams

The acquisition was structured as a share deal. On the seller's side, law firms Greenberg Traurig and Pinsent Masons provided legal transaction advisory, while Tax Advisor Magdalena Zamoyska handled transactional tax advisory. The purchaser, STRABAG Group, was advised by Act Legal on legal and tax matters, Savills on technical due diligence, and Baker Tilly on financial due diligence.

Kingstone Real Estate, headquartered in Munich, served as exclusive transaction advisor and deal originator for STRABAG Group. Following the closing, Kingstone Real Estate has also been mandated to provide long-term asset management for Olivia Star, supporting STRABAG throughout the investment lifecycle.

"We are very pleased to have successfully closed this landmark transaction," said Philipp Schomberg, Co-Founder of Kingstone Real Estate and CEO Poland. "We played a key role on the purchaser's side, providing transaction advisory services with institutional standards, coordinating the entire investment process and leading the contractual and commercial negotiations on the purchaser's side. Furthermore, leveraging our strong local network, we introduced Olivia Star to our investor STRABAG as an ideal match for their requirements regarding investment security, premium quality, and a shared long-term vision."

Schomberg added that Kingstone Real Estate will continue to manage the onboarding process and establish institutional asset management structures, representing STRABAG locally as an exclusive operating partner.

Market Context: International Capital Targeting Polish Offices

Kingstone Real Estate cited Poland's macroeconomic performance and yield differentials relative to Western European markets as factors behind investor interest in the country's office sector.

"We are currently observing growing interest from international investors in the Polish real estate market, particularly in the office segment," said Paweł Sobolewski, Managing Director Poland and Head of Fund Management at Kingstone Real Estate. "The yield spread compared to Western European markets still remains a key driver for international capital. Against the backdrop of Poland's strong economic performance leading the European countries' GDP forecast ranking, we expect further upward momentum in real estate pricing. Now is the time to invest in the institutional real estate sector in Poland and capture future value upside."

The firm stated it expects increasing inflows of international capital into Poland as a result of these dynamics.
