The building sits on an attractive sloping land in the residential area Paço de Arcos on the Portuguese coast in the vicinity of Lisbon. The architect Jorge Mealha designed this house as a number of functionally divided substances which react to the customer`s needs. He tried to soften their robust look in an interesting way – he created space where substances artfully communicate with the water surface. Light and shade become important elements. The water reflections on the house walls allow for a dramatic play and change of light throughout the day and give texture to the endless cement plaster walls that dress this house. The arrangements and size of the substances allow light to penetrate the core of the development. Metal blinds also reflect the movement of light from the exterior to the interior. The big smooth façade is of quite untraditional character.
