Netherlands-based MVRDV and Munich-based morePlatz have won a competition to design two office towers, Hafenspitze, in Mainz, Germany.
Planned to be built in the north-east of Mainz’ Neustadt, on the west bank of the river Rhine, the project will include a five-storey and eleven-storey tower that will transform the former shipping container harbour into a mixed-use city quarter.
The towers will come up on an area of 12,000m² with a public plaza at the centre.
The high-rise tower will feature a fully glazed facade on its four sides and angled windows to provide maximum viewing for people inside.
MVRDV said in a statement: "The floors are visually separated by dark horizontal bands clad in slate shingles which refer to the local architectural roof style."
The five-storey tower has a garden on the roof and is covered on its sides by prefabricated concrete panels that create a 3D visual effect due to the local Rustika stones.
Mainz Mayor Michael Ebling said: "MVRDV will create an architectural highlight in the Zollhafen quarter.
"The profile of the city will be given a contemporary twist along Neustadt’s future promenade by the Rhine, forming an antithesis to the medieval heart of the old town."
Construction work on the office towers will begin in autumn 2015.
