We were particularly inspired by the bold simplicity of the historic warehouse buildings along the Mississippi riverfront; like those iconic buildings, ours will be masonry, not glass.

Ground has been broken on the Eleven tower, designed by Robert A.M. Stern Architects, which will feature a variety of luxury amenities for its residents.

The US$190m (€171m, £147m) development in the US city of Minneapolis will cover 146,000sq ft (14,000sq m) and spread 41 storeys across a height of 550ft (168m).

It has been conceived to gradually taper as it rises, with floorplates of 12,500sq ft (1,200sq m) near its base and 6,800sq ft (632sq m) at the top.

Paul Whalen, partner at Robert A.M. Stern Architects, said: "Our design is based on classical principles, but we're giving Eleven a style all its own. We were particularly inspired by the bold simplicity of the historic warehouse buildings along the Mississippi riverfront; like those iconic buildings, ours will be masonry, not glass.

"Our massing will combine a lower element that reflects the scale of the neighbourhood urban fabric with a tower that will take our statement skyward – and offer fabulous views in all directions while marking the eastern edge of the reborn Minneapolis riverfront."

The tower will contain 118 residences, including 17 penthouses, and provide 12,500sq ft (1,200sq m) of commercial space.

Each residential unit will have panoramic views of the river and the city, as well as a private terrace providing a minimum of 196sq ft (18sq m) of outdoor space.

Residents will have access to a large landscaped rooftop deck with a 75ft (23m) rooftop lap pool, a fitness suite and multi-sport court and a demonstration kitchen with a dining area.

There will also be suites available for guests to stay in, a library, a golf simulator and a private motor court providing space for residents to pack and unpack their cars.

Located in the city's Mill District, residents will be close to both the river and to a park at the base of the tower.

Construction of Eleven is expected to to be completed in 2021.
