5. Krzywy Domek (The Crooked House), Sopot, Poland
Built in 2004, the Krzywy Domek is an irregularly shaped structure that is part of the Rezydent shopping mall. Szotynscy and Zaleski designed the building, which was inspired by Jan Marcin’s fairytale drawings. From the exterior, it seems there isn’t a single straight wall inside. The curvy lines give the building a whimsical look.
