Deck Lighting in Mariemont, OH

A good number of decks in Mariemont (ZIP 45227) are built flush with the inside floor, because stepping down out of these houses would look wrong. It reads beautifully and it takes away the one thing everybody uses without thinking about it: the step that tells you that you have left the house.

In daylight it does not matter, because the doorway, the frame and the change from carpet to timber all do the job. After dark, with the room lit behind you and the deck unlit in front, the glass is a mirror and there is no level change to feel for. Somebody walks out at the same height onto a surface that behaves differently underfoot, in the dark, having had no cue that anything changed. It is a small thing until somebody is carrying a tray.

So the threshold gets marked deliberately. A low fitting each side of the opening, throwing across the boards rather than out from the wall, puts a band of light on the deck immediately outside the door. It says the surface has changed without needing a step to say it, and it works from inside the room as well, because it gives the eye something beyond the glass to focus on instead of its own reflection.

The first board or two is where the light lands, and that is deliberate too. On a flush deck the boards nearest the door are the ones that take the weather at the sill, so they are also the ones worth being able to see: wet boards, a skin of ice, or leaves blown into the corner all show up in a grazing light that a fitting throwing outward would miss entirely.
