Any photos you can share?

Why not get the glass that can't be broken instead.There are also films to put on the glass.

A few suggestions based upon your lower photo, the fourth I guess. a. If you had the wall built, ask the guys that built it to perform your wishes. If it came with the house, call the former owner, whose name is on your deed. b. If the former suggestion is a dead end, let's analyze before we plan. You want to have a space for cooking and dining outdoors. This is such a beautiful yard, it does not deserve a portable BBQ unit exposed when not on fire, so put it in the garage as soon as it is cool. If you are going full hog for a builtin BBQ facility, perhaps it can be built against an existing wall, and just the dining area then needs the increased space. A 6' wide round table, requires about 12-14' for itself and the surrounding chairs and service area. Will you be happy with only a 15' or even a 20' section of wall moved? c. Remove the plants from the area that you plan to usurp, and about 5' beyond, and rent a sod cutter to remove all of the lawn from the vehicle entry point to the lower curved wall, by the palm, and stockpile it in shade, if possible. d. Have the contractor saw a vertical cut in the wall at the points of removal. Measure the distance of the plant bed to back wall. Cut the front bed wall that is to be removed with two sections of that overall bed dimention, so they can be placed as end walls for the two sections of bed that are no longer continuous. e. Have the contractor dig up the wall, and cut the two pieces to remain so they are free of the wall to be dumped. He will remove the existing soil from the bed. Modify any irrigation that exists, and then install the two wall slabs to their new duty locations, attach them to the remaining walls, backfill and replant as required.. f. The next step is to cultivate the compaced earth in the lawn area, rake it and resod. If the dining/BBQ areas are to be a dining terrace, you might wait until the sod is reestablished, say another month, before initiating that construction, as you don't want the sod to remain in a pile for long, or you will have to buy new. If it is to be a flagstone terrace, you can have that material delivered and stockpiled where the bed used to be, while the wall crew is just leaving. Will that fill your need. Give this post to the contractor so he can take measurements, and provide you an estimate overnight. Summer cookouts have already begun. Looks like we will miss the 4th of July bash.

Good luck that is a very skinny lot for anything except a very skinny house you might be able to have a small yard at the back but I am not sure about a pool maybe a lap one along one side of the back yard if you did something like this but 3 storeys tall and the carport underneath the main entry somehow
