Richard Rogers' Three World Trade Center nears completion in New York

The next piece in the redevelopment of the World Trade Center site in Lower Manhattan, a skyscraper by Rogers Stirk Harbour + Partners, looks almost complete in photos shared on Instagram.

Three World Trade Center is due to officially open in spring 2018, but most of the external work on the 1,079-foot (329-metre) tower appears to be finished.

Silverstein Properties, the real estate company that owns the building, said the project is 90 per cent complete and that work is currently taking place on the lobby areas in an Instagram post on 6 October 2017.

More images on social media show its orthogonal glass-covered form, with zigzagging structural elements exposed up the sides facing east and west, and lines vertically emphasising its north and south facades.

The building is designed by the London-based firm originally founded in 1977 by architect Richard Rogers, who was later joined by Graham Stirk and Ivan Harbour. The company is celebrating its 10th anniversary as Rogers Stirk Harbour + Partners this year.

Three World Trade Center contains two million square feet (190,000 square metres) of office and retail space. Its concrete core topped out in June 2016, while the perimeter steel structure reached its maximum height in October 2016. Installation of its glass facades completed in August 2017.

Spires topping each of its four corners, shown in early renderings but later dropped, would have taken the building's height to 1,168 feet (356 metres). Despite losing 89 feet (27 metres), it still remains in the category of supertall skyscrapers, which measure between 984 feet (300 metres) and 1,969 feet (600 metres) tall. It currently stands at the 10th tallest building in the US.

The tower sits between Four World Trade Center, designed by Japanese architect Fumihiko Maki and completed in 2013, and Spanish architect Santiago Calatrava's Oculus above the area's transport hub that opened last year.

Along with One World Trade Center, formerly known as the Freedom Tower, the buildings spiral in height around the memorial and museum dedicated to the 9/11 terrorist attacks that destroyed the Twin Towers and other nearby buildings. The layout adheres to the masterplan for the site, which architect Daniel Libeskind won an open competition for following the attacks.

Still to come as part of the revitalised World Trade Center complex include BIG's Two World Trade Center tower, which is yet to make it out of the ground, and a translucent performing arts venue by Rex.
