I wanted to nominate my neighbor in Mount Pleasant, whose garage deck I admire from my window every day. They have a detached garage on top of which they have built an amazing deck/cabana/outdoor space that really must be seen!
To check out the most spectacular and ingenuous spot they have created, you have to come through the alley behind the house, which is accessible by 19th St between Lamont St. and Kenyon.”
I hope this is the one. I was wandering up and down the alley and this was the coolest detached garage set up I saw. Definitely a sweet morning coffee spot.
