Plymouth Building – Embassy Suites
12 6th Street South, Minneapolis, MN
Nominated by: Ryan Companies and Terracon

The Plymouth Building – Embassy Suites is the result of remediation and renovation of a building that has been a staple of downtown Minneapolis for over a century. Once hailed as the “world’s largest reinforced concrete office building” after completion in 1911, the Plymouth Building had seen better days and was in disrepair. With two previous failed renovations, the Plymouth Building – Embassy Suites is an example of determination and resiliency.

Abatement of the building was immense and was made even more difficult given the building’s downtown location and that it is on the National Register of Historic Places, which meant the structure’s historical characteristics needed to be preserved throughout the renovation. An example of this was the need to restore the building’s 600 windows. Remediation efforts included the proper removal and disposal of over 8 tons of metals impacted ash from the building’s incinerator, nearly 300 pounds of mercury contaminated debris, and removal of a 10,000 gallon underground fuel tank and a 35,000 gallon fuel oil tank. Perhaps the most unusual remediation step was the removal and disposal of a 100-pound chlorine gas tank located in the basement of the building. Originally used to treat well water, the tank and it’s piping were severely corroded, making the tank a potentially explosive bomb. The Minneapolis Fire Department assisted in the removal of the tank, treating the experience as a training exercise. Lyon’s Pub, which is on the first floor of the building, remained open during the renovation project.

The redevelopment of Plymouth Building – Embassy Suites provides a much needed economic boost for the Hennepin Avenue cultural corridor of Minneapolis, and serves as a link between the Central Business and Warehouse Districts. The $104.7 million redevelopment project doubled the tax base from the 2015 level to the 2017 level of $1,108,507. In addition, the property value increased by over $42 million and 100 full-time jobs have been created with more to come when an on-site restaurant opens. Plymouth Building – Embassy Suites meets a market demand in increasing the number of hotel rooms in Downtown Minneapolis, a priority of Minneapolis’ Downtown 2025 Plan. Ultimately this redevelopment will spur future development and serves the local community with jobs and serves tourists and visitors as they come to Minneapolis.
