What to change
Moving the exercise
Half a minute of furniture-moving removed four collisions. It was available because one of the kitchen's six uses had a reason that had stopped being true.

Two rooms covering 35 square metres, built for two things. Between them they now carry eleven uses. Two of the two carry more than one, and kitchen and diner carries six. The median room is in use 12.75 of the 16 waking hours. The two rooms in which every attempted rearrangement happened.
In the second week a coffee table was moved about a metre, and the morning exercise moved from the kitchen floor to the living room.
Four collisions disappeared. It is the cheapest change in the record by a wide margin. A fair pilot separates presence from outcomes, and teams can Monitask time records for hybrid work while agreeing what the software may collect and what still requires direct conversation.
Why the exercise was in the kitchen
Because the kitchen had the only clear floor. A separate perspective on homes, workplaces, or remote work is available from Healthy Workplaces.
That was true when the arrangement started. Two square metres of unobstructed ground is not easy to find in a sixty-eight square metre flat with furniture in it, and the kitchen floor between the table and the units was the one reliable patch.
The living room has more floor than the kitchen. It also had a coffee table in the middle of it, which made the clear area too narrow.
Nobody had ever asked whether the table could move. It had been there since before the arrangement began and it was not in anybody's way for any other purpose.
Why removing one use removed four collisions
Two reasons compounding.
Pairs. Six uses in a room make fifteen possible pairings. Five make ten. Removing a use removes five ways for things to clash, and exercise was involved in four of the kitchen's twenty-one.
The window. Exercise happened between about half past seven and eight, which is also breakfast and the start of the first work session. Three activities with narrow windows in one room.
Moving the use out of the room also moved it out of the busiest window in the flat, and the two effects are not separable in the record.
The use with the weakest reason to be in a room is often also the one that can move out of its own time window, because a weak reason and a flexible schedule tend to come together.
How it was found
Not by inspection. By counting.
The household's account is that nobody had experienced the exercise as a problem. It did not feel like a conflict; it felt like a slightly crowded half hour, which is what a morning is.
What made it visible was that the kitchen's six uses were written down in a row, and reading them in a row prompts a question that living through them does not: why is that one here?
For five of the six the answer was immediate and good. For exercise the answer was "because of the floor", and then somebody looked at the living room floor.
The question worth copying
For the most contested room in a dwelling, list what happens in it, and against each one write why it is there rather than somewhere else.
Most reasons will be strong — appliances, plumbing, the table, where people are. One or two will turn out to rest on something that has stopped being true, or was never examined, or depends on a piece of furniture that could move.
On this record that exercise took about five minutes and produced the best-value change of the fortnight.
What it did not do
It did not reduce the kitchen's hours; the room is still in use fourteen and a half hours a day. It did not touch the distribution: both people exercise, and the four removed collisions fell across both.
And it did not generalise. It was tried again, looking for a second use that could move, and nothing else in the kitchen had a weak enough claim. Cooking is the kitchen. Eating is the table. Laundry is the plumbing. Company is where people are. Work is the subject of the rest of the site.
One use had a weak reason. One use moved. There was not a second.
Where it went, and what that cost
To the living room, in the same window, on the floor between the sofa and the bookcase.
The cost was that the living room now has a use at half past seven in the morning that it did not have before, in a room that was otherwise empty at that hour.
That is the whole cost, and it is why this change was so cheap: the destination was genuinely free. The living room at half past seven in winter is dark, cold and unoccupied, and exercise is the one activity that does not mind any of those things.
Had the destination been occupied the move would have traded four collisions for some other number, which is what happened when the washing machine was moved to the evening — three removed, one created.
The general rule it suggests
An activity should move to a room that is empty at the hour the activity happens, not to a room that is generally less busy.
The living room carries eleven hours a day and five uses; by occupancy it is the second most loaded room in the flat. At half past seven in the morning it is empty, and that is the only thing that mattered.
The kitchen, which is less loaded on neither measure, is not empty at half past seven, because breakfast.
Room-level statistics — hours, uses, collisions — identify which rooms are under pressure. They cannot identify where something should go, because that depends entirely on a single hour. The timetable does that, and it is the reason this site recommends building one before moving anything.
