The Madrid practice of José Blázquez and Juan Manuel Palacios designed this apartment building in the Valdebebas neighborhood of northern Madrid. A plinth will offer spaces for stores and offices, and the residential block will rise on it. Every unit has a spacious terrace stretching along the facade, and faces at least two directions. Following a rigorous order, there are three homes per floor, all with a corner and most of them looking over the garden. Using a simple construction system, the design achieves a high level of energy efficiency through passive saving techniques. Thermal imbalances are minimized and comfort is improved.
