"The master bedroom gets the perfect view that's all lake, and its placement on the corner of the house makes the plan flow and provides privacy," Lamaster-Millett says. In fact, the clients have nicknamed this room "the treehouse." The 8-inch-thick sill at the base of the windows helps save space by providing a spot for books, lights, a clock, etc. without having to bring extra furniture into the small room. "The extra pop-out enhances the feeling of floating in the trees," Lamaster-Millett says. The exposed beams, high ceiling and light color help the room feel bigger as well.
LSG (light-to-solar gain): The ratio between the SHGC and VT, basically how efficient the window is in allowing daylight in, while also blocking heat gain. The higher the LSG, the more light you get without the side effect of heat.
Low sills (meaning the bottom of the window is closer to the floor line) create windows that tend to have the proportions of doors. As such, they provide stronger connections between indoors and outdoors. Using lower sills also can make a smaller room feel much larger.
Tall heads (meaning the top of the window is closer to the ceiling line) provide much the same visual impact as lower sills. In fact, a conservatory derives much of its visual impact from the lack of any substantial wall structure above the windows.
Deep reveals (shown in the first photo below) enliven a window by providing not only a place to put things but also by emphasizing the three-dimensional quality of the surrounding wall. The deep reveal gives us a sense of the weight and solidity of the wall and the security the wall provides.
