Eindhoven grad Sophie Mensen runs an eponymous design studio out of the Netherlands, and we love her Column project. While it's not exactly practical for those of us who can't drill into a ceiling joist, it's pretty freaking cool:
I have chosen to work with a shape that gets absorbed by the space; the column, a constructive element of the house. A column is also a monument to impress, to remember important events that may not be forgotten. The column as a monument and the column as a constructive element are like the equivalent of my Column, but in the size and scale that fits to our interior.
...With my Column I propose the question is it a component of architecture or is it interior furniture.
