The Sun Doesn’t Care About Your Floor Plan
Why does the back of the house always feel so dark? A short argument for asking the sun first.

Most houses are designed room by room, and the windows come later. By then, the sun has already lost. We work the other way. Before we draw a single wall, we stand on the site and watch where the light comes from, and when.
North is generous
Steady all day, low in winter and easy to shade in summer with a decent eave.
East and west are moodier
East is bright and brief, a gift for kitchens. West arrives late, hot and low, and needs managing.
Light only reaches so far
Daylight travels about one and a half to two times the window height into a room. Beyond that, you’re relying on lamps.
The fix is rarely a bigger window. It’s a shorter distance: a courtyard, a high window over the bench, a stair void that borrows sky from upstairs.
Look at the edges
A deep window with splayed sides passes light across a surface before it reaches you. It feels far softer than a bright rectangle in a thin wall.
Choose surfaces that hold light
Matte limewash spreads light gently. Glossy tile throws it back hard. We test samples on site, in the afternoon sun.
Plan for the quiet hours
Decide early where the morning reading chair goes and which bench catches the last autumn sun. Lamps can be added later. Windows can’t.
