Brighten with a skylight. When dealing with an attic space that has sloped ceilings, have a professional roofer or a carpenter look at the possibility of adding a skylight. “Even a small skylight added between the rafters will add a dramatic amount of natural daylight to the space, making it feel much more like an extension of the main house,” says Clarke. “Any addition of natural daylight to an attic space or closet will make a big difference to the feel of the room.” But again, don't forget about the energy factor: If you add a skylight, be sure the space is equipped with both heating and cooling systems, as a skylight can affect temperature.
