Round four takes the two directions that led the first report and pushes each one three ways. A, The Threshold, gets a lit room, an open door and a line drawing. D, The Lit Window, gets a glow, loses its frame, and grows a roof. The palettes are held fixed from the first report so only the drawing changes. Each variation shows the lockup and a board so you can judge the system, not just the symbol.
“Come home.”


The same circle-and-square D, but the house inside its bowl is filled terracotta instead of cut out. A thin ivory gap keeps the house separate from the letter. You are looking through a doorway at a room with the lights on.
The original A read as a house through a door. This one reads as a home, because someone is in. It also gives the mark a natural two-colour state and a one-colour fallback, and the app icon in terracotta with a dark house is the best icon in the whole family.
The gap between the house and the D is what makes the drawing work, and it has to be held at every size. At favicon scale the gap closes up and the house becomes a blob, so the small version needs a wider gap or a plain cutout.
Recommended. The best drawing of A so far.

The house cutout breaks through the stem of the D at the bottom, so the negative space runs out to the edge like a door left open. A single terracotta dot marks the doorknob, or a porch light.
The most narrative of the three. The break makes the mark feel like an invitation rather than a symbol, and the embossed key tag on the board shows it holds in one colour with no dot at all.
Breaking the stem costs the letter. In the lockup the mark starts to read as a P over an L, and the D only comes back once the wordmark is beside it. The break should be narrower in the redraw, with more of the stem kept below it.
Most distinctive, least legible. A good idea that needs a tighter cut.

The D and the house are both drawn in one uniform stroke, with the house sitting on the baseline as the counter of the letter. One small terracotta square inside the house is a window.
The lightest and most architectural of the family. It looks drawn rather than stamped, sits well in a dark app header, and the window square doubles as a notification dot. The construction panel practically writes the vector spec.
Line marks lose their inner shape at small sizes, so this needs a heavier-stroke variant for the favicon, which the board already shows on the app icon. It is also the least warm of the three, and closer to what a generic architect's mark looks like.
The refined option. Pick this if Dwelio wants to feel like a studio rather than an app.
#F4EFE6#1B1A19#C4552D#8A9A7B“Someone's home.”


The same four-pane window, but the lit pane now throws a soft glow just past the frame on its own corner. Everything else stays crisp and flat.
The glow is what turns a grid icon into a window at night. It is the emotional fix D needed, and on a phone home screen it makes the icon look switched on next to its neighbours.
Glow is not a vector property. Print, embroidery and one-colour uses fall back to the flat mark, so the system carries two versions and the glow becomes a screen-only treatment rather than part of the logo.
The warmest D, but the glow is a screen effect, not a mark.

The outer frame is removed. What remains is the cross of the mullions and one lamp-yellow pane tucked into its lower right corner. Two shapes.
The simplest drawing in the report and the easiest to reproduce. The map application on the board is genuinely good: the cross becomes the marker and the yellow pane the selected state.
Without the frame it stops being a window. A thick rounded cross reads as a medical or pharmacy sign first, and the yellow square does not pull it back. It also lands close to a plus button in any interface it lives in.
Not recommended. Shown to prove the frame is load-bearing.

The top edge of the window frame becomes a shallow gable, so the mark is a small house whose body is a four-pane window. The lower right pane is lit.
This solves D's biggest problem, which was that a four-pane grid is a common software icon. Add a roof and it can only mean a house. It is the most ownable D, it works engraved on a brass plaque with no colour at all, and the solid yellow version is a ready-made map pin.
The lockup fuses roof and window into one outline, while the board draws the roof as a separate gable over a square window. Both work, but the redraw has to choose one. The fused version is stronger at small sizes.
Recommended within the D family. If D is the direction, build this one, fused.
