One Za'abeel

One Za'abeel is a mixed-use complex in central Dubai developed by Ithra Dubai, a wholly owned subsidiary of the Investment Corporation of Dubai. It combines offices, hotels, serviced apartments, residences and a retail podium in two towers that stand on seven basement levels and a three-level podium. The design architect is Nikken Sekkei; CTBUH lists ALEC Engineering and Contracting as main contractor.

According to CTBUH, the taller building, One Za'abeel The Tower, is 301.4 m high with 68 floors above ground and houses serviced apartments, hotel rooms and offices; One Za'abeel The Residences is 238.3 m high with 59 floors. Both were completed in 2023. The towers are connected by The Link, a sky concourse about 100 m above ground.

In March 2024 Guinness World Records recognised One Za'abeel as the world's longest cantilevered building, for The Link. The developer gives The Link's length as 230 m, with a cantilever of 67.277 m beyond the main tower.

01Plan2014 — 2018 · PLAN

CTBUH dates the proposal for the main tower to 2014 and the start of its construction to 2016. In 2018 Gulf News reported that ALEC Engineering & Contracting had been named main contractor, that excavation, shoring and piling were complete and that the seven-level basement was under way. The plan then described two towers of 67 and 57 floors linked at about 100 m, with residences, a hotel, serviced apartments, offices and a retail podium, and completion due in the fourth quarter of 2020.
