In the Northeast, it is so cold that I have consistently been layering my clothing. On any given winter day I can be found in 3 shirts and a sweater (and then the jacket to go on top).
But in general, your home really should be a series of layers that correlate to those who live there. The layers of your home are something that you may add to and take away from on a constant basis. But this layering is in the details.
