Mies visited the site in September of 1928, and had already produced plans by December of that same year. He shared his design with the Tugendhat family that new year’s eve, and with a few minor changes new plans were drafted and set into motion. Mies deployed his new functionalist concept of iron framework, doing away with load-bearing interior walls and allowing for more open and light spaces. The villa was composed of three levels (including the basement), with different floor plans and forms, each relating differently to the sloping site.
