Depends on the amount of rigidity you want and the permanence you can allow, in my mind. I do believe that a well constructed home-built one will work better than most that can be purchased.
I made mine using Stanley 1,000 lb. rated angle brackets which I bought at Home Depot. I sanded, primed, and painted them with textured black enamel. I mounted the brackets, spaced 16", to a 2 1/2" thick Boos rock maple cutting board using 2" lag screws. Then, I attached the brackets to the wall studs using 3" lag bolts so that the level of the cutting board was 44" from the floor. Total cost of the project was about $125. Several others I could have bought for similar money, but I had fun building mine.
Plus, I can set a glass of water on the board, jump up and down, and not see so much as a ripple on the surface of the water, so I know it is very stable. Positioning for best sonic results is, of course, a whole other issue.
I have also heard that combining a Neuance isolation platform by Greater Ranges (Ken Lyons) with a wall support (or solid floor stand) provides incredible results and is a real value.
Oops, I see you have plaster-covered brick, not a "stick-built" wall. Make sure you ensure the integrity of the masonry before proceeding and try to stick to using the expansion lugs on the cement joints as opposed to the brick, itself. Perhaps not easy to find, but the brick may well not provide a sufficient anchor and you would NOT want to come home to find that your support has given way!
