Courtyard Design

I have zero experience landscaping cement pads behind row houses, but figured I'd give it a whirl. I used ghetto AutoCAD; hopefully it gets the point across.

I think the entire slab needs to be replaced, so while doing this why not upgrade things a bit. Right? This includes adding a decent planter bed, a place for my garbage cans, a grill, and a 6' block wall all around the space to stop the Baltimore City rats from invading my zen garden and keep the local yokels out of my view.

With the slabtacular boringness of concrete, I'm thinking about a few slate tiles or shapes cut into the concrete (shown in cyan) to help spice up the floor.

I also want to hide my A/C unit. Using all cinder blocks is a bit cold, so I'm thinking about a wood fence around the A/C unit, on the gate, and for a neato bench in front of the japanese maple. I'm hoping to use cedar, but I'm only at Phase 1 so there is plenty of time to reduce cost and scope as I head forward. I will do the woodwork myself, and par for the course, I have zero experience building these aforementioned items. I'm not sure if the plants will survive in the places I've put them, so a bit more research is required. I'm worried about the roots going through the temperature extremes of an elevated planting bed. Also, lights hanging over the courtyard would be hot, so I threw a few in.

I need some height on the left side of my boring left wall, so why not add some bamboo. Not sure how it will hold up there, but I like the concept of it. The planting benches could hold herbs, a small fountain, some bonsai trees, and serve as a lovely bar in a pinch. Some planter boxes with sweet potato vine could help brighten up the place in the summer. I would think about painting the courtyard too, but I am at a loss for what color would look good. I have a general hatred toward beige/taupe, so that is out of the question.

If I have someone just do the concrete and block work, I think I can fill in the rest of the blanks. If the quotes come in too expensive for this work, the yard will stay an ugly broken up slab. All or nothing baby!
