We’ve seen so many incredible displays of design and architecture from A-Cero that now our expectations (and probably your as well) are getting  higher and higher when it comes to a company with such an amazing portfolio. So far it seems that the architects at A-Cero live up to their prestige and their latest residential project stands as a solid proof. The Concrete House II is a family project located in Madrid and stretches over a surface of no less than 1.600 square meters. The first impression when seeing its unusual architecture with gray concrete and vegetation ramps is that you are looking at an bunker entrance. The facade reveals large windows and uncommon shapes. The roof ensures this home’s ecological features as it contains solar tubular collectors, making this residence a sustainable project.  The site also includes a beautiful garden and a picturesque lake which complete the “dreamy” image that this home inspires.
