This phenomenal landmark Bay City property is as unique as they come! Its rich historic attributes can still be found throughout, along with substantial high-end upgrades in its entire mechanical system from the EPA's investment in our community during the 1990's, when they housed a supercomputer center on these grounds. You'll find sweeping views of Bay City from its tall windows, including the mighty Saginaw River. With its proximity to Downtown, the newly developed Uptown Bay City, the Columbus Ave. Business District, everything our community has to offer is just outside the front door! Schools (including colleges & universities), expansive medical facilities, government buildings, seemingly endless dining & entertainment options, recreation, and lodging are all within minutes! This stately structure offers a grand total of 20,592 sqft, with 6,864 sqft on each of the three levels (the lower level is fully accessible to the outdoors by a pedestrian door and drive-in, loading area), an elevator to each level, bathrooms (with multiple stalls) on the upper two levels and a lavatory on the lower level, multiple offices & conference rooms, a loading bay door to level 2, a floating floor to house additional wiring & cooling mechanisms, if needed, and generators on site for plenty of back-up power (gas is currently off to these, and they should be inspected, as they have not been in use for some time). The boiler is approximately 10 years old, There was a total roof replacement in 2018 with a transferable warranty, and environmental clean-up was done before the EPA moved in. Situated on just over an acre, there is ample parking for a variety of uses, and an abundance of drive-by exposure. You'll see darker ashphalt in the overhead photos- this is the portion of the lot that belongs to 135 Washington. Ease of access to highways & air travel will make commuting a breeze! This property is zoned C-3, which offers abundant uses (see docs section for explanation).
