&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[File:150northriverside2.jpg]]&lt;br /&gt;
&lt;br /&gt;
In April 2017, a striking new commercial tower located in Chicago was completed. 150 North Riverside is situated on a prominent waterfront site in the city’s West Loop.&lt;br /&gt;
&lt;br /&gt;
The tower is remarkable for the way in which its 54-storeys are built upon a base that is only 17 m wide, with the floors cantilevering out from the central core. It is also the first time that Grade 70 steel has been used in the USA.&lt;br /&gt;
&lt;br /&gt;
The design solution, by Goettsch Partners, was made necessary by the tower’s placement next to active train tracks to the west and the Chicago River to the east. The core-supported structure has a 20:1 height-to-base ratio, which, with its lack of perimeter columns, enabled column-free office floors above, as well as the incorporation of a public park with circulation routes, outdoor seating and an amphitheatre with views over the river. The tower’s first ‘full’ floor is on level 8, located 30 m (100 ft) above the plaza.&lt;br /&gt;
&lt;br /&gt;
[[File:150northriverside.JPG]]&lt;br /&gt;
&lt;br /&gt;
With a design that contextualised the river, vertical mullions along the tower’s east and west facades create a pattern of light and shadow that change throughout the day. Meanwhile, the north and south facades are divided into three vertical planes, stepped forward and back to provide outdoor terraces and to accentuate the tower’s slenderness.&lt;br /&gt;
&lt;br /&gt;
The tower was designed to achieve, and has been pre-certified, LEED Gold, with a design that aimed to provide ample natural light and open spaces on the interior.
