Designed by Alex Nogueira, 12.20 is a private small residence located in Campo Grande, Mato Grosso do Sul, Brazil. It is a tiny but terrific prefab home. A large sliding glass door takes up almost the entire rear wall of the home, being responsible for integration the external space to the internal one. The structure is apparent and mixed, both concrete and metal profiles are part of the aesthetic proposal, a game that tries to be subtle and objective.
