Torre Estronci 91 is located in an affluent area in Barcelona, l’Hospitalet de LLobregat. The apartments offer the ideal combination of modernity, quality, comfort, and energy efficiency. Aesthetically speaking, the characteristic feature of the block is the ribbons of horizontal Swisspearl panels alternating in white and black that encircle the building, making a strong graphic impression. The black areas incorporate the black-framed fenestration while the white strips clad the projecting balconies. This projecting and recessing of the facades creates a sense of relief on the elevations and prevents the block from being perceived as a monolithic volume.
