Casa Box is a simple, unusual small house designed by architects Alan Chu and Cristiano Kato. Located near Sao Paulo, Brazil the site was originally occupied by an old one-story house which was partially demolished and renovated to make way for the new home. The 3×5 meter white box is supported by an existing retaining wall and a new stone wall built in the fashion of the locale.
The main focal point of the home is the large picture window, which contains a fold timber privacy panel. The wood used for the doors, windows, staircase, shelves and furniture was originally used to form the white reinforced concrete box. The organic, rustic form and natural construction materials help to create a sense of comfort and homeliness in this tiny house.
