It’s hard to believe that just four short years ago there were people scoffing at the idea of balancing a 54-story skyscraper in the middle of a set of very active rail lines on the edge of the Chicago River. But here we are today, with the official opening of 150 North Riverside.
It’s not the first time that Goettsch Partners has cantilevered an office building on either side of a central core. But it’s the first time it was don’t not for aesthetic reasons, but to solve a real-world problem: how to fit 1.25 million square feet of wow in the middle of a rail yard.
Its predecessors next door at the Boeing Headquarters tackled the problem by using a steel truss system to float a portion of their building over the tracks. Goettsch went another way, starting with a narrow core at track level, and flaring outward high up. It’s like a tulip where the plant is mostly flower, and not much stem, but is still firmly rooted to the ground.
Riverside Investment and Development is rightly proud of its new tower. It gushes forth in the press below the photo gallery.
150 NORTH RIVERSIDE OFFICE TOWER DEBUTS IN CHICAGO
Developer Riverside Investment & Development establishes new standard for premier office tower and urban park
CHICAGO – Chicago-based developer Riverside Investment & Development celebrated the debut of the 150 North Riverside office tower, which opened for business in February, with an official ribbon-cutting ceremony today. Comprising 1.25 million rentable square feet, the building is located in Chicago’s West Loop on one of the most prominent sites in the city, bounded by Randolph and Lake streets at the confluence of the north, south and main branches of the Chicago River. Designed by architecture firm Goettsch Partners (GP), the tower features a very narrow structure at its base in order to fit between seven active Amtrak rail lines to the west and the river to the east. The building’s compact footprint opens up to highly efficient, column-free office floors above and allows for the majority of the two-acre site (more than 75%) to be developed as a landscaped public park, riverside amphitheater and riverwalk.
The 54-story building features a typical floor plan averaging approximately 28,000 rentable square feet, with the potential for up to 12 corner offices. The first full floor is Level 8, sitting more than 100 feet above the plaza. Building amenity spaces include Porter, a Brendan Sodikoff and 4 Corners restaurant concept; Sodikoff’s hamburger restaurant Small Cheval; a high-end terrace bar; organic sandwich maker Hannah’s Bretzel; an 8,000-square-foot, state-of-the-art fitness center; and a large conference center including a junior ballroom and multiple boardrooms—all with water views. The property also includes a one-story parking garage tucked underneath a portion of the plaza park space. Pre-certified LEED Gold, the building’s sustainable design maximizes energy efficiency and provides ample natural light and open spaces on the interior; an extensive green roof system also covers the entire structure. Building and technology systems are some of the most advanced in the market, with the property certified Wired Platinum for telecommunications infrastructure. Strong leasing activity resulted in approximately 85% of the building preleased upon opening, including the global headquarters for such tenants as investment banking firm William Blair & Co., Hyatt Hotels Corp. and Navigant Consulting, as well as the regional office of law firm Polsinelli.
“This building offers some of the highest quality office space in the market, as well as a public park and riverwalk as amenities for the city,” said John O’Donnell, CEO of Riverside Investment & Development. “We are very pleased to deliver a project that serves both tenants and the community.”
“Today 150 North Riverside officially takes its place as the newest jewel in Chicago’s architectural landscape,” Mayor Emanuel said. “But even more, this tower pushes Chicago’s architectural legacy into the 21st century by making an unmistakable addition to our skyline while building a new connection to our urban riverfront.”
The main challenge of the development was its riverfront site. The project combined three narrow parcels into a two-acre site, with the building effectively sitting on the easternmost parcel and the two western parcels providing development air rights for a podium over active train tracks. Utilizing a core-supported structure, the design features a compact building footprint with a 20:1 height-to-base ratio that opens the ground plane and allows for a dramatic, light-filled lobby. Taking cues from the river, vertical mullions undulate along the building’s east and west facades, creating an ever-changing pattern of light and shadow throughout the day. The north and south faces are divided into three vertical planes that accentuate the slenderness of the tower and step forward and back to mitigate the overall mass and provide select outdoor terraces. The largely open nature of the base, with no perimeter columns, offers the majority of the site as a landscaped public park with pedestrian pathways, outdoor seating and an amphitheather overlooking the river.
“The building is designed to take advantage of its challenging riverfront site,” said James Goettsch, FAIA, chairman and CEO of GP, as well as the design partner for the project. “In this case, how the building meets the ground is even more important than how it meets the sky.”
In addition to Riverside and GP, the project team included structural engineer Magnusson Klemencic Associates, MEP consultant Cosentini Associates, landscape architect Wolff Landscape Architecture, and general contractor Clark Construction Group, among others.
The building is also home to 150 Media Stream, a new media installation in the lobby that represents the convergence of art, architecture and technology in showcasing digital works from a rotation of distinguished artists and cultural institutions.
