Kansas City’s downtown skyline is rich with iconic silhouettes: Western Auto’s neoclassic sign, the grandeur of the Kauffman, the austere National WWI Museum and Memorial. But no list of KC’s built environment is complete without including the Tension Envelopes sign. 

Located in Kansas City, Missouri’s Crossroads district, the Tension building and its sign are just as much a part of Tension’s history as our Associates, products, and numerous innovations. This year, as we celebrate the 133rd anniversary of our company, let’s look at the historic brick building in the city we call our corporate home. 

Tension Corporation Headquarters 

Tension’s Kansas City headquarters are located at 819 E. 19th Street, a 9-story high brick building designed by legendary architect John McKecknie for Montgomery Ward. McKecknie was nationally acclaimed for his application of reinforced concrete in commercial structures, several of which — including the Tension Corporation headquarters — are recorded on the National Register of Historic Places.  

Construction of the building began in 1906 and was completed in 1911. It was originally used as a warehouse for Montgomery Ward. If you look closely, you can still see some of their original painted lettering on the external west side of the building: “MONTGOMERY WARD & CO,” “QUALITY,” “GOOD SERVICE,” “LOW PRICES.” 

A chute once used to transport coal to a boiler is visible from the basement of the building.

In 1914, the Berkley family, founders and owners of Tension, leased the 5th floor of the building, as Tension was growing out of its facility at what is now 20th and Tracy in Kansas City, Mo. The new arrangement was ideal as our business expanded. Trains ran directly behind the 819 E 19th building and allowed us to conveniently ship product and receive raw materials. In fact, for decades, the train railcars could come into the building, stopping to dump coal from the train into a chute that led to a coal-fueled boiler in the basement, and later, to deliver paper for our envelopes.  

Over time, Tension’s business continued to grow and we occupied more and more of the building. In 1930, Kansas City Power & Light purchased the building from Montgomery Ward. Included in that purchase was an adjoining garage and several nearby parking lots. KCP&L remained in the building until selling it to Tension in 1959. 

A Sign of the Times 

Shortly after purchasing the building, the iconic Tension Envelopes neon sign was installed on the rooftop. Although our company name changed to Tension Corporation in 2012, the sign remains as part of the Kansas City and Crossroads skyline. It serves as a reminder of our heritage and history, and our commitment to Kansas City.  

Water Towers  

For many years, two enormous 40,000 gallon water tanks were housed on the roof, connecting to a sprinkler system throughout the building as an early form of fire protection. The two wooden structures the tanks rested upon still remain. The architectural plan for one of the water towers from 1907 shows the “weight of water and tank 350,000 #.” 

Building Lights 

Lanterns on the front of the building feature the KC insignia.

At an unknown time, electric lights were affixed to the outside of the building. We believe that KCP&L, former owners and tenants of the building, installed these lights. Each lantern is scripted with a KC insignia and shines brightly on the front of our building each night and into the early mornings. Beginning In 2016 and 2017, the lanterns were refurbished as part of a major renovation project on the front side of the building, which also included tuckpointing, brick cleaning, repair and replacement and paint work on the front panels.
