🏗️ Kalipsous 5 Gerakas: Technical Specifications & Quality Characteristics
The project at 5 Kalypsous Street in Gerakas is a model residential development, combining high architectural aesthetics with the most modern construction methods.
1. General Project Information
Location: Kalypso 5, Gerakas, Attica.
Building Type: Luxury Apartment Complex.
Energy Class: A+ (Zero energy footprint with the use of photovoltaics and thermal insulation).
Seismic Protection: Design based on the latest Eurocodes and the Greek Regulation for Reinforced Concrete (EKOΣ).
2. Carrying Organisation & Construction Materials
At the current stage of work (March 2026), emphasis is placed on the structural adequacy and longevity of the framework:
Concrete (Cement): Use of certified concrete of class C30/37. The pouring is done with continuous flow control and the use of high-frequency vibrators to avoid voids.
Steel: Use of seismic-resistant steel category B500C, ensuring maximum ductility and safety.
External thermal insulation (Shell): External thermal insulation with a thickness of 10-12cm (expanded polystyrene or rock wool), which eliminates thermal losses and protects the building from temperature fluctuations.
