In March 2018, Cain International partnered with White Star Real Estate to develop Fabryka PZO, a 290,625 sq ft (27,000 sqm) mixed-use project in Warsaw’s Praga district on the site of the well-known former Polskie Zakłady Optyki factory.

Fabryka PZO encompasses two office buildings totalling 215,000 sq ft (20,000 sqm) and 120 apartments totalling 75,000 sq ft (7,000 sqm). One office building is fully let to a government tenant and all the apartments have been sold with residents beginning to move in starting in September 2021. Tenants and residents also benefit from a fitness studio as well as retail and restaurant offerings.
