I have an elderly customer who cannot bend over much at all due to heart problems. during our first meeting she pointed to the neighbors house which had a raised bed about 3 feet up made of concrete with a design in it. she said she wanted a bed like that but she "wanted it prettier" she said later she wanted it in wall stone. it is a small 1 story house and i wouldn't recommend it in the front due to the height it would have. My main question is if i put this wall in will it hurt the house due to the dirt running up on the brick siding. is there anything that i am overlooking or any other suggestions. please keep in mind i normally wouldn't install something like this but it is functional for her since she wants to take care of the beds a little herself to relax. any suggestions are welcome.
