Mecanoo has released visuals of Frankfurt Grand Central, a residential complex in Frankfurt, Germany, that will feature a copper-coloured tower.
Delft studio Mecanoo won a competition to design Frankfurt Grand Central for Phoenix and Gross & Partner, which is developing the scheme close to the city's Central Station.
It will be distinguished by its 40-storey tower, which is wrapped in copper-coloured metal to echo the "industrial atmosphere" of the railside site.

"The past few years have seen the beginnings of a transformation of the area," explained the architecture studio.
"The arrival of the new residential tower will be an important impetus for the transformation of this currently business-focused area into a mixed neighbourhood for living and working."
Alongside the 140-metre-high tower, Mecanoo has designed an eight-storey block for Frankfurt Grand Central that will be wrapped in the same metallic cladding.
Together they will host a mix of social and private housing, and be joined by a glass-walled "plinth" at ground level.

While the smaller block will be dedicated to affordable housing, the tower will host social housing on its seven lowest floors, and private units and penthouses on the upper levels.
The form of the tower will gradually change in accordance with these different property types, as Mecanoo has designed them each with differently sized and positions of balconies.

Frankfurt Grand Central will be complete ...
