by Ákos Budai | Office

Cushman & Wakefield has been responsible for the audit of the Sienna Center office complex and obtaining a BREEAM IN-USE International 2015 certificate for the scheme. The office complex received a “Very Good” rating in Asset Performance and an “Excellent” rating in Building Management. The scheme is owned by CA Immo.


Sienna Center is a complex of three office buildings providing nearly 20,000 sqm of leasable space. It was delivered in 1998 but its successive refurbishments have helped to maintain its appeal. The complex is nearly 100% let and has been recently revitalized to upgrade the common areas including its three reception desk areas, lifts and car park, and has been largely modernized to improve energy efficiency of its systems. 

Sienna Center is located at the junction of Sienna and Żelazna Streets and near Warsaw’s major public transportation hubs: ONZ Roundabout and the Central Railway Station. Cushman & Wakefield is the building’s property manager on behalf of CA IMMO.
