CP House is a minimalist house located in Barcelona, Spain, designed by Alventosa Morell Arquitectes. The project is based on a single family house and a warehouse in a plot between party walls, surrounded by high-rise buildings that make it difficult to obtain natural light and a comfortable relationship with the environment. Another important aspect is the fact that the only street that gives access to the site is very noisy, with a maximum decibel level according to regulations.
