Godfrey Hotel Chicago by Valerio Dewalt Train Associates

In early 2004, Valerio Dewalt Train Associates (VDTA) was commissioned to design a 16-story extended stay suites hotel at the corner of Lasalle and Huron Streets in Chicago by the site's original developer, Duke Miglin. It was his desire to employ a staggered truss structural framing system for the building - something new to Chicago - for its speed and efficiency of erection.

Construction began in 2007 but the project fell victim to the economic downtown in 2008, topped out with just the first components of exterior cladding installed. For three years the partially constructed structure sat, a rusting, tarp-wrapped reminder of the Great Recession, an eyesore on the skyline dubbed "The Mummy" by the neighborhood's residents.

In 2011, Oxford Capital Group examined the structure and saw potential in the unique, forward-looking staggered steel truss framed design. Working with The Gettys Group, Oxford developed a new upscale "boutique-lifestyle" hotel concept envisioned for repurposing the partially built structure. With this new concept in-hand, Oxford engaged VDTA to make modifications to the original building design while retaining the iconic design of expressive structural frame and assembly of shifted, taut, rectilinear building masses. The hotel opened in February 2014.

Realizing the flexibility of a staggered steel truss system's full building width spans afforded by the staggered spacing of the trusses, the unfinished existing structure was easily re-planned for The Godfrey to provide 221 guest-rooms, spa and fitness facilities, street level lobby and hotel support spaces. In addition, the design team extended the utilization of the 4th floor level out onto the rooftop over the parking podium to create a 15,000 SF indoor|outdoor urban roofscape. All-in-all, the revised program is a significant change from the building's original extended stay suites/low amenity concept.

The form of the Godfrey Hotel is an expression of its staggered truss structural system invented by William LeMessurier in 1966. In this system, story high steel trusses span across the full width of the building and are staggered from floor to floor. Precast planks span from the top chord of one truss to the bottom chord of another truss on the floor above. This system is very light in weight, can be erected rapidly and has a very low floor to floor height.

It also is a system where the deep trusses allow a remarkable freedom to express the program of the hotel, where today's guest is looking for that unique room satisfies their unique needs and preferences. From its base the building form is offset three times, creating rooms of varying depths, creating 26 different room types for a hotel with 221 keys. In addition, the long span trusses create large clear span public and amenity spaces on the 4th floor.

The structural system allows the design to celebrate the human variability its guests, expressing this fact with a form that seemingly defies gravity obeying its own fuzzy logic. It is the exception, along LaSalle Street, that proves the rule that all tall buildings should be boxes no matter what their function.
