Peris+Toral was founded in 2005 by Marta Peris and José Toral. Together they dedicate their Barcelona-based practice to research on dwelling and building methods, with theoretical and written work that addresses areas such as the relationship between film and architecture, modern ways of living, low-impact construction systems, and comfort. This monographic issue features a conversation between the architects and Eduardo Prieto, where they explore systems of exception and their attention to perception, depth, and gradient. Fourteen works are profiled, including several Spanish social housing projects, the Pere Garau Health Centre, and a house-studio in Barcelona.
