Hi, had a brick planter built. It is approx. 3ft in width by 10ft in length. Was thinking about using about 3-4 ft and put a separate wall to make it a planter box and a bbq/fire pit. Doing this by putting sand on the bottom, a layer of brick and thinking of something to put coals in it to be able to use it as a bbq. Do you think this is feasable? Or a crazy idea? I really don't have a lot of space to build an actually fire pit or bbq so does anyone think I can do this? Someone please help me??? I really appreciate it.
