Blackjack21 Apartment Complex

Blackjack21 is a sustainable development that combines housing and business accommodation with fantastic views over Amsterdam and the IJ river. In addition to the supply and assembly of the complete precast concrete framework, CD20 was also responsible for the design, engineering (category 5) and preparations.

Smartly designed and rapidly assembled

The building has balconies with safety glass balustrades around its entire circumference. The balconies have been mounted on steel supports which have in turn been fastened to the floor slabs that separate the different storeys. The CD20 team installed the floor slabs on the columns and walls in record time, complete with plumbing and electricity. Since façade girders were expendable, the glass fronts extend from floor to floor.

Cooperation within CPC project

The development of Blackjack21 occurred in the form of a CPC project: collective private commissioning. Residents and businesses were offered residences or working areas (45 to 350 m²) that could be designed and fitted out according to their own taste. This self-build project involved CD20 and architect firms BO6 and BNB as well as co-developer Sprangers.
