Casa Lela is a house with a simple beauty, located in Santa Cruz do Bispo, Portugal, designed by Oficina d'Arquitectura. The client had family vacation estate, in the country side nearby Porto, with a house that has been in his family for some generations. On the border of the property there were two abandoned house, connected to each other, that were later acquired by the client with purpose of converting it into a guest house. The intention of the architects was to do a single object in communication with the main property, so they did a single cut in the object create an opening. This cut was carefully chosen in order to achieve the best shape relation between the two old houses. As the same material were used in the walls and roof, in the end they become one single crystallized object. This shelter is completed by adding solid wood pieces that organize the space, while the floor material escalates from the ground to become furniture.
