41 - Work Community **
If you spend eight hours of your day at work, and eight hours at home, there is no reason why your workplace should be any less of a community than your home.

236 - Windows which Open Wide *
Many buildings nowadays have no opening windows at all; and many of the opening windows that people do build, don't do the job that opening windows ought to do.

13 - Subculture Boundary
The mosaic of subcultures requires that hundreds of different cultures live, in their own way, at full intensity, next door to one another. But subcultures have their own ecology. They can only live at full intensity, unhampered by their neighbors, if they are physically

6 - Country Towns *
The big city is a magnet. It is terribly hard for small towns to stay alive and healthy in the face of central urban growth.

246 - Climbing Plants
A building finally becomes a part of its surroundings when the plants grow over parts of it as freely as they grow along the ground.

25 - Access to Water *
People have a fundamental yearning for great bodies of water. But the very movement of the people toward the water can also destroy the water.

66 - Holy Ground *
What is a church or temple? It is a place of worship, spirit, contemplation, of course. But above all, from a human point of view, it is a gateway. A person comes into the world through the church. He leaves it through the church. And, at each of the important thresholds of his

27 - Men and Women
The world of a town in the 1970's is split along sexual lines. Suburbs are for women, workplaces for men; kindergartens are for women, professional schools for men; supermarkets are for women, hardware stores for men.

36 - Degrees of Publicness **
People are different, and the way they want to place their houses in a neighborhood is one of the most basic kinds of difference.

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.

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

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.
