The cubic figure of the house has two stories organized in a square floor plan divided by an asymmetrical cross. The first floor has various levels that adapt to the topography. In the lower one there is a triple height room that works as a pivoting vertical space, as a kind of void that captures the sense of vertigo and exposure to the cliff. The massive perimeter is somehow emptied by a rather continuous and fluid interior, with openings cardinally positioned in opposite sides of the volume. Despite the evident obstruction of the geometrical abstract piece in nature, and despite the undefined material transparency between the concrete and the granite of the surroundings, there is an intended sense of rest and gravity incarnated in the constructed place. The work was done, with a small mixer and four wheelbarrows, in horizontal stratums that matched the height of half a wooden board. All the work was built with hand-made concrete, using untreated wooden formwork. The same rough and battered wood of the formwork were recycled to wrap the interior and to build sliding panels that function both as doors to hide the services of the perimeter and as shutters that cover the windows when the house is left alone.
