Ron Arad Architects has revealed a twisted tower that is narrow at the base but widens at the top, built as the first phase of the ToHA office complex in Tel Aviv.
British-Israeli designer Ron Arad designed the offices to take advantage of a constricted site by expanding and rotating the 29-storey tower as it rises.

The building is set to complete later this year, with a second 70-storey tower planned for the next phase of the Totseret Ha-Aretz (ToHA) project due to be built by 2024.
The first building has a stepped facade as the floors wider towards the middle of the tower before reducing slightly before the roof. Horizontal louvres and the overhang from the rotated floor plates create sunshades for levels below.

Seven lower narrower levels in the building, contain the building's technical plant. This leaves the roof level free for several restaurants, two terraces, and a perimeter walkway. A facade of cross-mounted panels forming a pattern of X shapes clads these levels. The woven pattern makes the facade permeable to allow for ventilation for the plant facilities.

The building's entrance is marked by a 30-metre-tall cable-supported glass wall that leans out from the building.
A seven-storey-high lobby has views all the way up to the roof via an atrium void that runs through the building, allowing daylight to penetrate the offices from another inside.

Sky is visible through this 100-metre-high vertical space, and trees have been planted in the centre of the foyer. Ac...
