What is fixed
The constraints nobody chose
Orientation, glazing, heating and the position of sockets were settled before anybody worked there, and they account for most of the endings.
What a household cannot move
Forty-two of the ninety-four endings come from two properties of the building, both settled before anybody worked in it.
Orientation, settled before anybody arrived
Twenty-four light endings concentrated in eleven places, four of which account for more than half. The constraint that money cannot touch.
Glazing and heat
Eighteen temperature endings, twelve of them in three dwellings, and all three with a working place at the far end of the building.
Sound, twelve endings and one party wall
Noise is the most evenly spread cause in the record and the hardest to attribute. Three of the twelve are a wall; the rest are a city going about its day.
Sockets, three endings and a long cable
The smallest named cause in the record, the cheapest to have got right at the point of building, and the most expensive to fix afterwards.
Forty-two of ninety-four
How the endings divide between what a household can reach and what it cannot, and why the division does not follow the order of size.
The cheap one and the uncorrectable one
One of the four constraints could have gone differently for very little money. One could not have gone differently at any price.
What a letting particular does not say
Three of the four constraints in this record are invisible in how a property is described, and one of them costs nothing to establish.
