Damn, that was incredibly lucky for the house next to it not to come down too. I wonder if he did the napkin math to make sure of that, or if they just got lucky.
Probably some combination of fertilizer and welding gas or propane. Big boom but not a lot of "push". Loading everything to the street facing side of the house and above ground could use the walls/rooms to direct the blastwave out of the house towards the street and away from the neighbors house. Also could have loaded everything into the basement (seems like a house like that could have a basement) under the rooms where it would be most likely that somebody would try to enter. Then the entire basement would focus the blastwave up.
Honestly it didn't look that powerful of a blast, and very contained to one side.
My guess is he opened the valves on a gas stove, let the kitchen fill up, and when he fired the flare gun it went off. Lots of fire but very little in terms of explosion.

Gonna be interesting to see the first case of "To call it an improvised explosive device is, frankly, insulting."
Explody things are... weird.

The building was a duplex, so that would explain the one sided explosion.
