The flagship store project developed for Mango Tekstil Türkiye on Beyoğlu’s Istiklal Street — in the historic building formerly known as Vakko — was completed by DEA YAPI on a 5,580 m² construction area on a turnkey basis between 2008 and 2009. The nine-story structure, comprising two basements, a ground floor, and six upper levels, was delivered with all architectural, electrical, and mechanical design, approval, and implementation managed end-to-end.
The scope included infrastructure for 5 elevators and 3 escalators, renovation of a 380 m² front façade and 510 m² rear façade, and fabrication of the main load-bearing steel staircase using 54 tons of steel structure. A 90 m³ water reservoir with control room was embedded in the foundation, while a dedicated transformer and cell system, generator, ventilation, fire suppression, and full electrical installations were completed in compliance with international standards. The scope also extended to architectural decoration, mechanical, and electrical works at the Mango store in Gaziantep Sanko Mall.
Executing construction on Istiklal Street — one of Istanbul’s busiest and most historically sensitive corridors — requires a specialized engineering discipline in urban logistics, coordination with neighboring structures, and pedestrian traffic management. DEA YAPI brought its integrated design-and-build expertise to this challenging urban context.
Since 1988, DEA YAPI has delivered turnkey retail and corporate store construction services across Türkiye, bringing the same commitment to on-time delivery and quality assurance to the Mango Istiklal Street project.
