My neighbors and I are considering putting up a swing set in the alleyway between our houses. The space is about 10' wide, and the house walls on both sides are brick (about 4" thick).
Which of the following alternatives would be best, if we wanted to have two swings there, each capable of holding a child up to 80 lb. or so?
Put up brackets on both walls to hold the pole.
Drill holes in both facing walls, put in the pole, fill the holes with concrete.
Forget about attaching to the walls; get a freestanding swing set and attach it to the ground.
