Pentominium, located in Dubai Marina, will potentially be the tallest residential tower in the world. This tower had a unique challenge, in that it had to respond to two different conditions on the site: the density/proximity of the neighbors and the extreme environment pressures of Dubai. Therefore, the building has two different sides that center around a shared core.One side is a simple extrusion that reaches the full height of the building. This side is primarily southern-oriented and utilizes a system of balconies and a vertical layer of glass to mitigate solar gain. As the building rises this layer of glass becomes wider and functions as a wind break to help protect the balcony from the higher-velocity winds as one gets to the extreme heights of the tower.The other side of the building is a staggered shape, alternating between apartments and voids of sky-gardens. This is achieved through the introduction of six five-storey-high pods that cling structurally to the core. This alternation allows for either communal or semi-private spaces and thus enables the tower to “breathe” within its dense context.The result is a very thin, lightweight 516-meter tower that lightly sits into its setting of extruded neighbors and powerfully maintains its presence in its context and climate.Andrew Bromberg of Aedas is the Lead designer of the project.
