2 - The Distribution of Towns
If the population of a region is weighted too far toward small villages, modern civilization can never emerge; but if the population is weighted too far toward big cities, the earth will go to ruin because the population isn't where it needs to be, to take care of it.

142 - Sequence of Sitting Spaces *
Every corner of a building is a potential sitting space. But each sitting space has different needs for comfort and enclosure according to its position in the intimacy gradient.

156 - Settled Work *
The experience of settled work is a prerequisite for peace of mind in old age. Yet our society undermines this experience by making a rift between working life and retirement, and between workplace and home.

179 - Alcoves **
No homogeneous room, of homogeneous height, can serve a group of people well. To give a group a chance to be together, as a group, a room must also give them the chance to be alone, in one's and two's in the same space.

65 - Birth Places
It seems unlikely that any process which treats childbirth as a sickness could possibly be a healthy part of a healthy society.

51 - Green Streets **
There is too much hot hard asphalt in the world. A local road, which only gives access to buildings, needs a few stones for the wheels of the cars; nothing more. Most of it can still be green.

118 - Roof Garden *
A vast part of the earth's surface, in a town, consists of roofs. Couple this with the fact that the total area of a town which can be exposed to the sun is finite, and you will realize that is is natural, and indeed essential, to make roofs which take advantage of the sun and

119 - Arcades **
Arcades - covered walkways at the edge of buildings, which are partly inside, partly outside - play a vital role in the way that people interact with buildings.

46 - Market of Many Shops **
It is natural and convenient to want a market where all the different foods and household goods you need can be bought under a single roof. But when the market has a single management, like a supermarket, the foods are bland, and there is no joy in going there.

Shops rarely place themselves in those positions which best serve the people's needs, and also guarantee their own stability.

112 - Entrance Transition **
Buildings, and especially houses, with a graceful transition between the street and the inside, are more tranquil than those which open directly off the street.

86 - Children
The task of looking - after little children is a much deeper and more fundamental social issue than the phrases "babysitting" and "child care" suggest.

73 - Adventure Playground
A castle, made of cartons, rocks, and old branches, by a group of children for themselves, is worth a thousand perfectly detailed, exactly finished castles, made for them in a factory.

If people cannot walk out from the building onto balconies and terraces which look toward the outdoor space around the building, then neither they themselves nor the people outside have any medium which helps them feel the building and the larger public world are

All the world's a stage, And all the men and women merely players: They have their exits and their entrances; And one man in his time plays many parts, His acts being seven ages.

45 - Necklace of Community Projects
The local town hall will not be an honest part of the community which lives around it, unIess it is itself surrounded by all kinds of small community activities and projects, generated by the people for themselves.

115 - Courtyards which Live **
The courtyards built in modern buildings are very often dead. They are intended to be private open spaces for people to use - but they end up unused, full of gravel and abstract sculptures.

159 - Light on Two Sides of Every Room **
When they have a choice, people will always gravitate to those rooms which have light on two sides, and leave the rooms which are lit only from one side unused and empty.
