An open floor plan is currently one of the most desirable design features in a home. While this type of space can be elegant and modern, it doesn't really afford you a lot of privacy. In this house, from the designers at Russian studio Fedorova, doors that run run from the floor to the ceiling manage to blend into the walls and create the illusion of a wide open space, while still allowing the homeowners to close off rooms when necessary. Combined with beautiful natural materials and simple clean lines, this family home is a beautiful tribute to the art of interior design.
