I was placed on a challenge to prepare a study of Interior Architecture of four spaces (three Sanitary Facilities and entrance area where it has access stairs to the bedrooms). Since early the idea of cozy ambiances that transmit tranquility, comfort, but at the same time, exist an irreverent attitude transforming each space into something unique. In fact, we used soft colors, warm and comfortable textures, with a harmony, a formal dialogue between the various spaces. There must be communicative in our house, a home should be an extension of the people who inhabit it, each space must talk and must all speak the same language.In the hall the location of the staircase, this perspective is very strong, and usually the entrance hall it's a presentation space of the house and distribution, therefore, draw the ladder so that is another feature of this space, as the small library, or other use. The first level of stairs occupy the entire width, and mirrors shy about 25cm serving bookshelves. In the second section, the ladder develops in the wall recessed blades for better use of lighting.In Sanitary Facilities, was intended to give a more welcoming environment, entering the wood element where is the sink and mirror the entire time.
