Deep-set windows make a cottage dark and beautiful at once. The thick stone walls that swallow the daylight also create those wonderful deep reveals and generous sills — one of the most characterful features of an old cottage. The trick is to work with them: coax the most daylight you can through by day, and turn the recess into a glowing feature by night. Here's how.
Why the Windows Are Deep
Cottage windows sit within walls two feet or more thick, built of stone or cob for strength and insulation, so the glass is set deep into a generous reveal with a broad sill. It's a beautiful feature — but it does mean less daylight reaches the room, since the deep reveal shades the window. Understanding that is the key to making the most of it.
Bounce the Daylight In
The single best trick is to paint the deep reveal a pale, light colour so it reflects daylight into the room rather than absorbing it. A dark reveal swallows the light; a pale one bounces it inward. Pair that with a mirror hung opposite or beside the window and a small deep-set window works much harder — worth a whole extra window, almost.
Keep the Dressings Minimal
Heavy curtains crowd a small deep window and block precious light, so simple treatments suit best — a blind set within the reveal, light curtains, or sometimes nothing at all to show off the recess. The deep reveal is itself a lovely feature; let it be seen. Minimal dressing means maximum daylight and maximum character.
Light the Recess at Night
A deep recess goes dark at night and can become a black hole in the wall. A small lamp on the sill keeps it glowing — and reads beautifully from outside, giving the cottage that warm, welcoming lit-window look on a winter evening. A lamp in a deep window is one of the cosiest small touches there is.
The Sill as a Display
A deep cottage sill is a natural shelf, and styling it is half the pleasure. A lamp, a stack of books, a jug of foraged stems from the garden, a few plants, a row of small treasures — a little collected and seasonal, in the relaxed cottage spirit. A jug or pot of garden cuttings on a deep sill, glowing beside a lamp, is the cottage window at its best.
Plants Love the Light
A deep sill is a fine spot for plants that want the light a window gives — herbs in the kitchen window, geraniums, a row of little pots. Greenery on the sill softens the stone reveal and brings the cottage garden indoors. By a lamp at night, the plants catch the warm glow and the whole recess feels alive.
A Window Seat if You Can
If the reveal is deep enough, a cushion turns the sill into a perch — a place to sit with the light behind you and the garden in front. A deep window seat is one of the great gifts of an old cottage, and a small lamp nearby makes it a reading nook after dark. Not every window allows it, but where one does, take it.
Work With What the Walls Give You
Deep-set windows are a constraint and a gift in equal measure — less daylight, but more character and a wonderful sill. Fighting them is pointless; working with them is a joy. Bounce the daylight, dress them simply, light the recess warmly, and style the sill, and a deep cottage window becomes one of the most charming features in the house.
Getting More Light From a Small Cottage Window
To get more daylight from a small deep-set window, bounce and reflect it: paint the deep reveal a pale colour so it reflects rather than absorbs, hang a mirror opposite or beside the window, and keep dressings minimal. A pale reveal and a well-placed mirror make a small deep window work far harder — almost worth a whole extra window in a thick-walled cottage.
Lighting the Recess at Night
A deep recess goes dark at night and can become a black hole in the wall, so a small lamp on the sill keeps it glowing — and reads beautifully from outside as a warm lit window. A lamp plus a jug of garden stems and a few plants turns a deep sill into one of the cosiest, most characterful spots in the cottage.
