MO House is a minimalist house located in Valparaíso, Chile, designed by Gonzalo Mardones Viviani. MO House is located at an area of steep slope facing the sea coast of Chile in the commune of Zapallar. The house is buried with clearly no intention to interrupt the wonderful view to the horizon from the public road, so it is accessed by stairs and ramps going deep into the mountain to discover again, from inside the house, the sea, coast and breaker.

The access to the house is in the middle level, which contains the public areas of the house: living room, dining room and kitchen. The rooms were located on the ground floor with direct access to the garden; and the main room was designed to be at the upper floor, on a suspended volume that dominates the view and highlights the clear intention of the house to capture the horizon.
