Fibonacci Square is the redevelopment of the AIB Bankcentre site in Ballsbridge, Dublin 4 to create Facebook’s European HQ Campus.  The development includes the demolition of 4 no. office blocks and the development of 2 no. 6 storey office buildings (with setback on 4th and 5th Floor) over three levels of basement.

The structure of the buildings is reinforced concrete with post tensioned floor slabs that have allowed spans of 12 metres of open plan space to be achieved whilst reducing the slab depth and the overall weight of the entire building. The setback floors are of steel frame construction. A 33m bridge links the office buildings. Cantilever trusses will allow the façade to hang from the top of the building structure in areas. The building is set to achieve a LEED Gold Rating.
