Designed by Danish architectural company Bjarke Ingels Group at a total cost of $1.9 billion, The Eleventh will comprise of two towers situated between Manhattan’s 10th and 11th avenues. Real estate investment and development firm HFZ Capital Group is also involved in the project.

The towers will be home to a new Six Senses Hotel Resort and Spa, the first hotel under the Six Senses brand constructed within America, housing over 130 rooms, alongside over 200 sophisticated new residential units. The twisting towers will enable residents to access full views of Manhattan’s skyline on one side, whilst views of the Hudson river can be seen on the other as a result of this unique design, reaching heights of 300 and 400ft.

Incorporating stone and metal facades, the build will blend naturally within the environment. HFZ Capital Group Chairman and Founder Ziel Feldman said, “It's an urban location, yet our site is flanked by the greenery of the High Line and the calm of the Hudson River.

Six Senses operates some of the most beautiful eco-conscious resorts in the world and we knew they were the right partner to explore that connection to nature and create something unique to New York City."

Such choice of material ensures the towers do not dominate the area in which they are situated.

The 950,000sq foot mixed use development will also be home to a unique spa, promoting wellness, alongside several retail units, embedding sophisticated technologies to attract further tourism to the area. The towers will also appeal for corporate guests with the inclusion of meeting rooms which can be utilised for individuals and groups.

Sustainability is a key focus within all new developments, at which The Eleventh is no exception. The Six Senses brand has long promoted the use of sustainable construction, at which the towers have been designed with the focus of obtaining LEED Certification, with the design of rooms reflecting an eco-friendly and appealing space.

The development will also house a restaurant, in addition to an open-air pedestrian promenade, which is being constructed in collaboration with Friends of the High Line.

China’s Broad Group builds 10-storey apartment in 28 hours

Broad Group, a private manufacturing enterprise located in China has constructed a 10-storey steel apartment in 28 hours

The China-based manufacturing enterprise Broad Group has managed to construct a 10-storey steel apartment building in just over a day. Constructed in the city of Changsha in China, the company used bolt-together modular units known as its “Living Building System”.

Broad Group, a manufacturing company based in Changsha, constructs a range of air-conditioning, heating, and prefabricated structural units. It accomplished the challenge in 28 hours and 45 minutes, enlisting help from three cranes and an on-site workforce. 

Broad Group’s “Living Building” system

Designed to be easy to transport and install, Broad Group’s “Living Building” system uses components that are able to fit into a standard shipping container, and then be bolted together when they reach the site. Ductwork and wiring are fitted directly by the factory, the company said. 

As part of the system, Broad Group’s B-Core steel slabs are used as structural elements which, the company claims are 10-times lighter and 100-times stronger than conventional slabs. The company also says they have the ability to resist earthquakes and typhoons, and that it costs less than a carbon steel building and has low energy consumption. 

Broad Group also says that buildings of up to 200 storeys, supertall towers, could be built using the same modules due to the B-Core steel slabs’ strength and lightness. 

Other Broad Group projects 

Broad Group has completed other significant projects in the past. In 2012, for instance, it attempted to build the tallest tower in the world in Changsha at 838m, which would have made it 10m taller than the Burj Khalifa in Dubai. The company claimed it could have made the building, named Sky City, in just eight months. However, due to not receiving approval, it was never built. 

In 2015, the company accomplished another “speed-build” challenge, constructing a 57-story tower using the “Living Building system”. It was completed in just 19 days.
