This 8-bedroom mansion at 1900 S. Prairie in the Prairie Historic District of the South Loop has been on and off the market since 2008.
The house is known as The Elbridge Keith House.
Built in 1870, here’s more information from the listing:
Built in 1870 and designed by J. R. Roberts, the Keith House is a breathtaking property situated along Chicago’s historic Prairie Avenue. The original “Gold Coast” in the late 19th century, the opulent Prairie Avenue was once home to the city’s elite with legendary Chicago families from the Pullmans to the Fields calling the tree-lined avenue home. Named for banker and merchant Elbridge Keith, the Keith House is one of the few remaining original mansions in the heart of the Prairie Avenue Historic District. Today, the home sits along a secluded cul-de-sac just moments from bustling Downtown Chicago.
We actually chattered about this house back in 2008.
Back then, the listing described it as a “project.”
But it had the same uses as it has in 2020. The first floor is still being used as event space and there are two apartments on the upper floors.
The current listing has pictures of the first floor including its magnificent crown molding and inlaid floors.
In the 2008 listing, the coach house had been “renovated.” You can see what it looks like in the current listing.
See our 2008 chatter here.
This house is zoned DX-3 and the listing says it can be a single family home, a condo conversion or a boutique hotel.
It also has historic tax incentives.
Built on a 50×176 oversized lot, it has a 2-car garage in addition to the coach house.
Here’s an old picture that I used in the 2008 post. I still love the horse in the front yard.

Here’s more detail from the 2008 listing:
For the first time in many years historic 1900 S. Prairie Avenue is on the market. Built in 1870 it is thought to be the oldest existing mansion on the Avenue. Elbridge Gerry Keith a wealthy banker and wholesaler hired architect Jonathan W. Roberts to design this three story structure and stable.
The main residence is about 7100 square feet. Constructed of top quality materials including Joliet limestone and red brick this home has many of its original details still intact: plaster moldings large windows fire place mantels mahogany woodwork and parquet inlayed floors.
The home has been transformed over the years. The 2100 square foot stable was recently renovated and converted into a two bedroom two bath coach house with beamed ceilings hardwood floors and a family room and an attached two car garage.
Homedelete argued this week that the coronavirus is going to change everything for Chicago.
“That’s why, my friends, I say, drive out of the city limits until you can find an acre or more. In the matter of weeks, the Big City lifestyle is suddenly toxic, and will remain so for generations. The irony of his all is that big cities, for most of history, were cramped diseased filled places of poor people. Anyone with any money at all got out of the city and into the countryside and spent time at a villa. Anyone with means LEFT the city, and out of that experience came the suburbs. The new urbanism made an assumption that turned out to be faulty: big cities would remain clean, safe and disease free, and right now, most big cities are no longer.”
This house was pending in the last week of March 2020, during the coronavirus.
It has since been re-listed.
When we chattered about it in 2008 it was listed at $3.35 million.
It’s been reduced to $2.695 million.
Is it a myth that the rich have always “fled” Chicago and other cities, as Homedelete argued?
This mansion is now 150 years old.
