Windowless study
Ten by ten. One door. Light is a rumor.
An interior room sold as a den. No window. One overhead. Work happens here because it is the only door you can close.

What Room Lab concluded
Spend, earned
strongLight · severepressure on its worst conditionLight looks like the governing problem. Temporary light path.
- Why
- Light is the primary friction at 88. Light scores 88. Daylight, artificial distribution, glare, dark zones. Comfort at 50 is real, but it is not the thing a body hits first. No lamp is declared anywhere in this room, so after dark the only light is whatever is overhead. Addresses light failure and dark zone with a derived cause behind it. It runs about $25–150, takes about 60 minutes, and is undone the same day.
- Caveat
- Unnamed: paint LRV of the walls; whether the door has a glass pane that could be added later.
- NextTest
- A lamp in the dark corner and a task lamp at the job. Different color temperatures if sleep and work share the room. What to watch: Sit at the job 30 minutes after sundown. Can you read a page without the overhead?
Driven by Light score (88). Strong — every condition scored, ranked, and clear of a tie.
Where the walk narrows
The widest way through measures 30" at its tightest, against Desk. The minimum is 36".
- Pinched walk
- Hatched fails its clearance, or is causing friction
- Primary walk narrows to 30" beside Desk; it needs 36".
- Primary walk ≥ 36" fails, with 30" because of Desk.
- Door landing ≥ 30" passes, with 86".

Free moves first
Clear the primary walk
Remove anything that is not furniture from the walk, then look hard at Desk, which is what narrows it. Bags, mail, laundry, the chair that became a hook.
How to tell it worked: A body walks it without turning the shoulders.
Move one heavy thing across the room
Take the largest piece on the crowded side and put it on the empty one. Do not buy something for the empty side — that is the expensive version of the same fix and it adds footprint.
How to tell it worked: Both halves of the room hold something with weight.
Then one reversible test at a time
Temporary light path
A lamp in the dark corner and a task lamp at the job. Different color temperatures if sleep and work share the room.
What to watch: Sit at the job 30 minutes after sundown. Can you read a page without the overhead?
Move the largest piece once
Shift the sofa, island, or bed off the crossing. Live with painter's tape marking the old footprint. Do not buy a new piece this week.
What to watch: Primary path ≥ 36". Conversation or work still functions.
Not worth buying yet
- Another rug before the walk is clear. Rugs do not fix circulation. They hide it.
- Hardwired statement fixture. Electrical is a watch or professional review is required. Prove the path with plug-in light.
- Decorative storage cubes for the pile. A lid is not a sort. Empty the pile first.
