Ideas for what I can do with this space?

I have a 19' x 12' space between my garage and my house there is a breezeway that connects the house to the garage.... This area is difficult to mow and also contains the access door to get into the crawl space. Need something that is extremely cheap, and doesn't require heavy machinery(would require driving over my septic tank to get to it), and can also make it so I don't have to mow it. I ought of using patio blocks but leveling the area is going to be a bit of a challenge because of the access door and the septic....any other ideas.....oh the ground soil is also extremely sandy like but grass and weeds still grow
