The commercial building of the Porcelana Company lies by Vouliagmenis avenue in Athens, and it is designed by the architect N. Ktenas. It consists of two basements, a ground floor and three floors. With a total area of about 6000m2, it is characterized by its long spans, the absence of beams in the basement level slabs and its mixed construction method, partly of reinforced concrete and partly of composite steel.
The defining element of its architectural conception is the left side wall, which supports a beam grid structure covering the roof. On the other side the grid is connected to the roof of the building through a series of short columns. In case of earthquake, these short columns can safely handle the increased stresses that occur due to shear on this side of the building.
The composite construction in three floors is connected with the main reinforced concrete framework, but there is also a joint between it and the outer wall for earthquake resistance purposes.
The basement slabs have a constant thickness of 35cm, with about 10m spans, and contain light weight polystyrene cylinders. The slab of the foundation is of variable thickness, 20-60cm. The building features curved staircases of exposed concrete.
Cubus has implemented all the work phases, from preliminary design to construction supervision.
