A HOUSE, LIKE A KALEIDOSCOPE, NEEDS MOVING LIGHT. IN THIS SENSE WE DESIGNED THE CONCEPT OF THIS HOUSE DESIGNED FOR A LAND IN THE PLAYA VISTA CONDOMINIUM IN XANGRILÁ, RS. VOLUMES THAT HAVE DIFFERENT HEIGHTS, LEAVING TEARS IN THE COVERAGE FOR NATURAL LIGHTING WAS THE WAY TO EXPRESS THIS IDEA. THE HOUSE, AS WELL AS THE DISCIPLINE, HAS A SUSTAINABLE HOUSING WITH JUST ONE DORMITORY. WE HAVE BEEN MAKING A PROJECT FOR THE HOUSE ON THE BEACH FULLY FACING THE LAND. WITH THE MINIMUM POSSIBLE DIMENSIONS AND ENABLING A VARIOUS QUANTITY OF LAYOUTS. THAT'S WHY EFFICIENCY IS NOT ONLY USING TECHNOLOGY TO SAVE ENERGY, BUT IT IS ALSO DESIGNING WITH THE LOWEST AMOUNT OF MATERIALS.
