In June last year, Seattle-based retailer Nordstrom announced plans to build a skyscraper that would house the company's first city flagship. Now that building is set to be the world's tallest residential tower.

Reports are circling regarding the project’s height after design illustrations of the proposed skyscraper were featured on the New York YIMBY blog courtesy of an anonymous tipster close to the project.

According to the drawings, the tower is set to rise 1,775 feet (541 metres), a fair distance higher from the original plans calling for it to rise 1,394 feet and 88 floors, as listed on the Council on Tall Buildings and Urban Habitat (CTBUH).

The new height is also noticeably one foot lower than the topped out One World Trade Centre skyscraper. That tower reaches 1,776 feet, a reference to the year of the US’ independence.

The skyscraper is set to house seven floors of Nordstrom retail on its lower floors. Floors eight to 12 will feature a hotel, with higher levels housing luxury condominiums.

Having an iconic department store housed within a skyscraper marks an unconventional move for a large retailer.

“It’s probably the most interesting thing to happen in retail in a long time,” said Ronald Ruskin, former Gimbels chair and managing director for retail broken Lansco, to The New York Times.

The tower will house the highest roof in the United States

Adrian Smith+Gordon Gill will be the architects on the project. The firm is behind the world’s current tallest tower, the 828 metre-high Burj Khalifa Dubai. Extell have signed on as the Nordstrom Tower’s developers.

The skyscraper offers a modern aesthetic; tall, slender with a steel and aluminium exterior. The 93rd floor appears to hold an exposed roof. The skyscraper itself will rise 1,479 feet, at which point a spire will stretch skyward to its uppermost height.

Nordstrom Tower will take the “tallest roof” title in the United States from Chicago’s Willis Tower, which stands 1,451 feet high.

It will also surpass residential skyscrapers, including Mumbai’s One World Tower (442 metres) which is currently under construction and Rafael Viñoly’s 432 Park Avenue skinny skyscraper in Manhattan (1,397 feet).
