Not enough space in my present dwelling... so I'm adding on... not by much but enough so I dont have to keep breaking down my set up after each session. A very humble space... an odd shape but its all the lot setback allows... a mere 6.5 feet by 16 feet. Nice that a hot spell has started up, my pasty white skin will fry and peel. Been some 10 year since I engaged in an earnest building project, hope I havent forgotten much. Is fiberglass insulation enough to dampen street noise? Well I'm thinking of beefing the walls up with a layer of styrofoam insulation (will help avoid the heat here too)
