This gorgeous house (in Valle de Bravo, Mexico) came across my path via Inhabitat today. "Casa en el Bosque" (designed by Parque Humano Architects) means "House in the Forest" and has some extremely beautiful surroundings complete with mountain views. The house was constructed using locally sourced and sustainable materials and was designed with the surrounding nature in mind. The inside of the home actually has cutouts in the ceiling with pine trees growing through them!!
