Three distinct designs by three of Barcelona's founding fathers of 19th C Modernista architecture. Casa Amatller (#41) was designed by Puig I Cadafalch and shows Islamic influences from Spain's Moorish past while Casa Batlló (#43) reflects Gaudi's desire to portray nature in form, there are virtually no straight lines and the house takes on a dragon like shape with the roof imitating scales. Montaner's Lleo Morera at #35 combines elements of renaissance styling partnered with Gothic and Greek decoration, adding to the architectural confusion - hence the name 'Apple' (Block) of Discord. Sadly they are not open to the public but worth a look anyway.
