Unfortunately, not much is left of what I’m fairly sure was the summer kitchen for the home. I’ve heard rumors that some believed this to be enslaved housing—unlikely, given that slavery ended in December 1865 and the home wasn’t built until ~1884. In the 1880s, summer kitchens were fairly common—you can read more here: What is a Summer Kitchen?
At some point, the kitchen was expanded and converted into a greenhouse or garden shed. Back in 2017, I hoped to repair this old relic, but only a wall or two of it is standing now, and the insurance company wants what remains to be demoed. <sigh> So we plan to take it down once we take ownership and will attempt to salvage as much of the old brick as possible for use on the property. They’ll come in handy along the way and deserve to be put to good use.
