Space efﬁciency is one of the most important design considerations in any tall building, in terms of making the project viable. This parameter becomes more critical in supertall (300 m+) residential towers, to make the project attractive by offering the maximum usage area for dwellers.This study analyzed the space efﬁciency in contemporary supertall residential buildings. Data was collected from 27 buildings, using a literature survey and a case study method, to examine space efﬁciency and the main architectural and structural design considerations affecting it. The results of this research highlighted that: (1) central core was the most common type of design parameter; (2) prismatic forms were the most preferred building forms; (3) the frequent use of reinforced concrete was identiﬁed, compared to steel and composite; (4) the most common structural system was an outriggered frame system; (5) the space efﬁciency decreased as the building height increased, in which core planning played a critical role; (6) when building form groups were compared among themselves, no signiﬁcant difference was found between their effects on space efﬁciency, and similar results were valid for structural systems. It is believed that this study will help and direct architects in the design and implementation of supertall residential projects.
