Architect Benjamin Romano of LBR&A Architects has completed a three-sided skyscraper, the 57-storey Torre Reforma that is situated on Paseo de la Reforma in the heart of Mexico City. Standing tall at 246 metres, this is the tallest tower in the sprawling metropolis. Encompassing 87,000 sq. m. of oor area, the building has ofces and retail space. It is organized into 14 four-storey clusters, conceived as buildings within a building, with each cluster having its own interior garden. Its sculptural shape was derived from various factors including environmental concerns. The tower, composed of two concrete walls that form a sharp edge that intersect, has its upper portion chamfered, resulting in a triangular surface. Slits in the walls enable natural light to enter the gardens inside the building.
