Sparked by an influx of young professionals and artists, the factories and working class homes that once dominated Barcelona’s Poblenou neighborhood are giving way to innovative residential architecture. Hired by a young Spanish-Swedish couple to refurbish a two-story row home, Nook Architects realized that the house needed more than just a facelift. Due to poor construction, the architects had to start from scratch. What began as a modest remodeling project became an opportunity to “delete the visual limits of the usual house with multiple levels,” says Nook Architects. The result is an airy and art-filled home with colorful details from top to bottom.
