William H. Whyte's Design Theory

William H. Whyte’s criteria for a successful urban space:
 
Sittable space
  • Quantity, variety & flexibility are key
  • Integral seating is important, people will happily sit on ledges, steps, walls, sculptures, planter edges, fountain edges, etc
  • Opportunities should be available in both sun and shade
  • Circulation & seating are complementary – people often prefer to sit somewhere along their chosen route, not in a zoned seating area
  • Although weather-dependent & generally less comfortable, lawns provide additional seating
  • Moveable chairs are preferable to fixed benches for groups to communicate
  • Corners of steps can enable 45° angle spaces for groups (3+ people) to sit & communicate
  • Benches that are designed to be sat on from two sides should 2 backsides deep to allow for physical and psychological comfort
“The human backside is a dimension architects seem to have forgotten.” William H. Whyte
 
   “People tend to sit most where there are places to sit.” William H. Whyte
 
 
Streets & Plazas
  • Human scale
  • Ideally, not elevated or sunken – no greater than 1m change in level if unavoidable
  • Doors & windows should be included, blank walls are hostile
  • Shops, cafés, etc should be built flush with the pavement
  • Corners & junctions are popular areas for chance encounters, planned meetings & for observing others
  • The edges or fringes of plazas tend to be preferred, central open space is less used through feelings of exposure & high visibility (the amphitheatre effect) and often lack of sittable spaces
  • Access points are often busy and provide secondary use through meeting points & visual access to the main site
 
 
Light
  • Direct or deflected daylight (via buildings or water) is essential to the feel of a place
  • Sun traps vary in appeal according to seasonal temperature!
 
 
Food
  • Easy access via street vendors & outdoor cafés advertises availability
  • Circulation & tables should be close enough to encourage social interaction, whilst still enabling ease of access & comfort
  • Waste bins should be in plentiful supply, emptied regularly & well sited. Ease of use & social pressure will assist in keeping the area clean & tidy

“Food attracts people, who attract more people.” William H. Whyte
 
 
Water
  • Accessibility is important – people should be able to see, touch, taste, hear & smell water
  • Drinking fountains are too rare but an important resource
  • The white noise of moving water, although often loud, is perceived as pleasanter than traffic noise, which it can mask
 
 
Trees
  • Provide shade – welcome in summer
  • Large trees create a sense of domain
  • Improve the microclimate through transpiration & wind protection
  • Help mitigate solar glare & urban heat island effects
 
 
Triangulation
  • Sociability: crowds attract people & encourage social interaction
  • The ‘shill effect’ – e.g. if you stand and point at a distant object in a public place, eventually other people will join you to see what you are pointing at.
  • Shill [OED definition]: “Person employed to decoy or entice others”
 
“What attracts people most, it would appear, is other people.” William H. Whyte
 
 


“It is difficult to design a space that will not attract people. What is remarkable is how often this has been accomplished.” William H. Whyte
