Architect Manuel Aires Mateus presented an interesting project of the house, located on the outskirts of Leiria in Portugal. Its functionality is quite usual: there are several bedrooms and living room there. The white facade design is very simple, but it is the main feature of the project at the same time. Such an “cardboard box”, actually, is not so primitive. The void in the centre of living area provides natural lighting. Its very important, because private areas are at street level under the plot in an intimate environment. Uncomplicated but high-quality interior decoration and furniture emphasize the minimalist style.
