The House in Sevres by Colboc Franzen & Associes provides the concept of having two homes in one. With a lower level where the exterior is primarily made of glass, and an upper level whose exterior is mainly made of wood, the difference between the two floors is a clear focal point in this design.

My favorite part about The House in Sevres by Colboc Franzen & Associes is the floor-to-ceiling windows on the outside of the lower level.
