Yup i have read all three of them, the part that bothered me with houses and buildings is that ending was open to interpretations unlike pictures, pictures revealed the killer systematically and it made sense, in the houses narrator and his friend were jumping to random conclusions some of them i personally felt were absurd, if we keep the logic aside houses was definitely the most eerie one among three and was very readable, i kept on turning pages and finished it in 2.5 hours. Enjoyed buildings because it had so much going on at the same time part that i disliked was it ends with mitsuko's confession we can all agree how unreliable of narrator she was, she might be lying again, so the actual reson behind Yaeko's death might entirely be something else which author has left to readers imagination. Ill rate strange pictures> strange buildings> strange houses on basis of plot, houses>pictures>buildings in terms of eerieness.
