Martifer Metallic Constructions was responsible for the refurbishment and expansion of AM Growth, in the centre of Madrid. The building combines aluminium, glass and steel and is an icon in the AZCA financial district due to its distinctive architecture. 

Martifer was responsible for supplying and assembling 3,000 sqm of curtain walling with curved glass edges, metal cladding and 140 tonnes of steel for a metal exostructure. This structure supports the new slabs on the upper floors and crosses the façade in the opaque zone - its rigorous execution was therefore fundamental to the building's dynamics.
