Al Majdoul Office Tower

Riydah, Saudi Arabia

Client: Al Daffah Group
Size: 800,000 sq.ft. (74,000 sq.m.)

This unique spiral shaped commercial tower features 52 storeys of office floors, a penthouse restaurant, observation deck, and a grand entrance lobby. The podium at the base of the tower houses prayer rooms, meeting facilities, and a retail component at street level. Four levels of underground parking accommodate approximately 1,000 cars. The extensively landscaped entrance plaza features reflecting pools, fountains, and substantial planting, which precedes the impressive glass canopy as an integral part of the lobby. The landscaped berms and thick planting material act as wind barriers, supplementing the patterned stone paved plaza. Zoned elevator systems ensures that the delivery of passengers to their floors happens without unnecessary delays.

In order to create this outstanding glass tower without affecting the building’s efficiency, a simple square floor plate of post-tensioned slab rotates 2.5 degrees at each floor, internally supported by a single sing of structural columns and the circular service core. The curtain wall building envelope is slightly tilted and partially recessed at each floor to complete the buildings’ unique form. During the day, the building benefits from the sun control created by the recesses on every floor.
