In this case, I'm planning for people in the shots as well, where I'll trade DoF for shutter speed since IS won't help as much in that scenario. For shots of static scenes, yes the 24-105mm would be better (in fact, I typed in a phrase to that effect in my post, then deleted it before posting). But also, the 24mm prime has much less barrel distortion than the 24-105mm at 24mm, which would help for the building itself (though obviously a tripod and the TS-E 24mm is the best choice if possible).
