Award winning Spanish architect Alberto Campo Baeza designed Rotonda House at the summit of a hill, north of Madrid. The building captures a 360° panoramic landscape from the belvedere situated above a two storey podium made of local limestone. The building is based on a 12m by 12m grid divided into nine 4m x 4m squares, giving it a Palladian flavour. Photo Javier Callejas. Alberto Campo Baeza
