THE SITE FOR THIS HOUSE IS AT THE TOP OF A HILL, OVERLOOKING THE OCEAN FROM HERMOSA BEACH, MALPAIS, COSTA RICA. ITS GEOMETRY IS INSPIRED BY THE CURVY LINES OF THE NATURAL CONTEXT, TRYING TO IMITATE THE ENVIRONMENT. ITS MATERIALITY ALSO CREATES A DIRECT RELATIONSHIP WITH ITS IMMEDIATE CONTEXT. THE BLACK CONCRETE EXTERIOR WALLS CREATE A BACKGROUND FOR THE GREEN VEGETATION AROUND IT WHILE CREATING CONTRAST AND PRIVACY WITH THE WHITE INTERIOR BEDROOM AREAS. THE SLIDING GLASS DOORS ON THE SECOND FLOOR SOCIAL AREA OFFER A VIEW OF THE HILLS, WHILE THE BIG ROOF’S WOODEN FINISH CREATES A CONTINUITY FROM THE INSIDE TO THE OUTSIDE. THE OPENNESS OF THIS SPACE CREATES A NATURALLY VENTILATED AND ILLUMINATED ENVIRONMENT, WHILE SOLAR WATER HEATING AND RAIN WATER HARVESTING MAKE THIS HOUSE A HIGHLY SUSTAINABLE STRUCTURE.
