340 on the Park Building

The 340 on the Park Building is a Contemporary skyscraper designed by Solomon Cordwell Buenz, and built between 2004 and 2007, for a reported $244 million dollars, in Chicago, IL.

340 on the Park Building is not the only name you might know this building by though. The building is, or has also been known as 340 E. Randolph.

Its precise street address is 340 E Randolph St, Chicago, IL. You can also find it on the map here.

In 2007 when it was compelted, 340 On the Park was Chicago's first residential high-rise to be granted the LEED certification, exemplifying unparalleled environmental consciousness in the city's housing landscape.

Solomon Cordwell Buenz was the architecture firm in charge of the architectural design.

That being said, architecture is a complex discipline involving many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the 340 on the Park Building a reality:

• Magnusson Klemencic Associates in charge of Structural Engineering
• Lend Lease as the Main Contractor
• Magellan Development Group as the Main Developer

The 340 on the Park Building can be categorized as a Contemporary building.

The 340 on the Park Building uses a frame structure made of reinforced concrete columns and beams.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade uses a non-load bearing curtain wall system. This means the curtain wall modules are anchored to the building's structural frame, typically by being attached to the edge of the floor slabs. The curtain wall system connects to the slabs using brackets, anchors, and mullions, which transfer the loads imposed by wind and temperature changes, to the building's primary structural elements.

This setup allows the curtain wall to accommodate differential movement between the facade and the structural frame, such as thermal expansion, floor deflection, or sway from wind forces. This system's integration with the slab edges also allows for continuous insulation and weatherproofing layers.

From an aesthetic point of view, the facade features a blue glass curtain wall with some light-gray opaque bands that organize the facade in stacking sections of 5 floors each.

There are also recessed balconies on each floor, although not every unit has one.
