Casa Lela is a minimalist house located in Santa Cruz do Bispo, Portugal, designed by Oficina d’Arquitectura. The client had a 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 the purpose of converting them into a guest house.

Since the architects wanted to do a single object in communication with the main property, they did a single cut in the object to create an opening. This cut was carefully chosen in order to achieve the best shape relation between the two old houses. In the end, they become one single entity due to the fact that the designers used the same material in the walls and roof.
