I took a look around the map and have a few suggestions for you.
This whole room here feels awkward to navigate and favors people attacking the spawn rather than people coming out of it. Attackers can easily abuse this floor as cover to spam into the door. I would suggest having the staircase flipped so you can easily approach them as someone spawning in to help make the room flow better.
This little spot seems strange and unintentional. I'd just fill it in with a large brush or maybe a closet to store cleaning supplies or electronic appliances.
Just across from this room, there is another window that is clipped. This one isn't.
If the bench has no collision, I'd make all of the brushes beneath the kits have no collision as well. kind of a weird bump, and people would get caught on them trying to jump up the hedge or something. Not to mention it eats splash.
I'd also clip these ledges to make them easier to walk up, since I got caught on them trying to jump to the awning quite a lot.
Same goes for these.
On a more general note, I love all of the mobility possible in the map. It's a bit small and there aren't really any large combat areas to use, so scout and soldier could be doubly powerful on this map. Still, the roofs are loads of fun to navigate! Love all the windows you can jump on, too.
I also enjoy the hightower-esque finale. You obviously want this map to be more focused on DMing which is cool!
