Two volumes crown the top of a hill at Playa Misterio a gated beach community 117 Km. south of Lima.One cube built in exposed concrete comes from the earth while the second one located 2.40m apart and made out of glass looks as if it is “floating” on the site.The “concrete block” houses the social area of the dwelling in its lower levels and the master bedroom at the top. The “glass block” accommodates the children’s area in two levels.The space in between the blocks is occupied by a staircase designed as a series of sculptural elements that connect the hard appear of concrete to the soft look of glass provoking light and shadow effects as the sun visits the house during different hours of the day.
