D. Building Beautifully: Placing Craftsmanship Alongside Architecture and Urbanism in New Urbanism

  1. 1. 12th June 2009 Building Beautifully: The Low Carbon of Craft Ben Bolgar Director of Design 1
  2. 2. 80% CO2 reduction with 3 billion more people !? 2
  3. 3. Decoupling GDP & Consumption from Environmental Impact Source: European Commission, 2005. 3
  4. 4. Possible cultural and cognitive shift When resource/carbon consumption becomes capped how will industry/habits change? Activities which take longer with lower impact and greater satisfaction will occur Low consumption entertainment – sports Low consumption building - crafts 4
  5. 5. Green Building 5
  6. 6. What can be learned from Traditional Construction? 1. It’s simple (solid wall) and transferable (self-build to industry) 2. Materials often sourced locally – organic and reusable/recyclable 3. The core is straightforward leaving time for architectural detail 4. Usually based on high thermal mass 5. The materials tend to get better with age 6. They degrade elegantly helping to sustain value 7. The details are designed to be practical and beautiful (evolution) 8. They are easy to patch and repair (by non specialists) 9. They don’t rely on fast track production that may have built in redundancy (non availability of components) 10. They are generally non toxic (with exception of lead!) 6
  7. 7. What’s wrong with it? 1. Slow to construct and labour intensive 2. Sometimes heavy use of materials – stone/brick 3. Excessive heat loss through wall and air gaps 4. Acoustically poor 5. Limited by small spans 6. Can be high maintenance 7
  8. 8. Elegant long term solution? 8
  9. 9. Organic, simple and thermally enhanced 9
  10. 10. BRE House precedent – paired houses 10
  11. 11. BRE House precedent – paired houses 11
  12. 12. BRE House precedent – paired houses 12

  14. 14. 14
  15. 15. Organic, simple and thermally enhanced 15

  20. 20. The Art of Land Platting 1 yard = 3 ft = 0.9144 m 1 rod, perch, or pole = 25 links = 16.5 ft 4 rods = 1 chain 1 chain = 4 rods = 66 ft = 100 links 10 chains = 1 furlong 1 link = 1/100 of surveyor's chain = 7.92 inches 25 links = 1 rod = 16.5 ft 100 links = 1 chain = 66 ft 1 furlong = 10 chains = 1/8 mile = 220 yards = 660 ft = 201.168 m 8 furlongs = 1 mile 1 mile = 80 chains = 320 rods = 1,760 yards = 5,280 ft = 1,609.344 m league = 3 statute miles = 4,828.032 m 20
  21. 21. Convert that to housing •1 chain = 4 rods = 66 ft = 100 links •60-66ft gives 4 houses at 5m wide or 3 houses at 6.7m wide i.e. 4 no. 2-bay houses or 3 no. 3 bay houses •Platting by multiples allowed for roughing out at right stage in process 21
  22. 22. The Modern System – Platting on a 30m (15m module) Housing options on 30m land plat: •6 no. 5m wide houses – 2 bay terrace •5 no. 6m wide houses – 2 bay/paired houses •4 no. 7.5m wide houses - 3 bay terrace/ 2bay alley •3 no. 10m wide houses - double fronted/mews •2 no. 15m wide houses - double fronted/flats 22
  23. 23. The Modern System – Platting on a 30m (15m module) Block options on 30m land plat: •45 x 60m small alley block •60 x 75m medium alley block •75 x 90 m large alley block •Squarer blocks for parking courts of large blocks of 120m length may be appropriate for lower densities 23
  24. 24. 24
  25. 25. Blocks giving a well over-looked public realm 25
  26. 26. A diverse set of ‘Streets, Squares & Crescents’ 26
  27. 27. Liverpool Road residential with set-back 27
  28. 28. Liverpool Road residential closer to centre 28
  29. 29. Grand street of large paired houses 29
  30. 30. Normal terraced street 30
  31. 31. Residential Street with Pub on axis 31
  32. 32. Lonsdale Square 32
  33. 33. Bla 33
  34. 34. Gibson Square 34
  35. 35. Bla 35
  36. 36. Barnsbury Square 36
  37. 37. Part 3 Deck of Spatial Composition Cards 37
