Evolutionary Design Principal

Modern building practices and laws demand a blue print or similar be submitted with a development application. Given this you need to know what your development will look like before you start.

Now it is clear why this is so, if we look historically at the results of uncontrolled development. Everything from slums, to unsafe housing or community destroying developments litter the past and the present. There are people who either do not know better, take short cuts in their own financial interest, commit fraud or poor workmanship with no regard to social, environmental and financial impacts. See below for further details on the Problems "Blue Print" requirements can cause below.

Evolutionary design principals are considered in Christopher Alexander et al.. work in the n0ties.


The Problem is when we try and direct the way we do things in laws and regulations there are many benefits, but there are a few problems.

  • Developments can't respond as easily to
    • New Knowledge
    • Observations and changes in the environment
    • Innovation in materials or design
    • Changes in materials costs or availability
    • Input from partners and trades people into the construction and development process
  • Design can not respond as easily to
    • On site observations of the environment
    • On site observations of the development itself
    • Contributions from participants and visitors
    • State of the art materials and methods
  • Regulation and certification authorities
    • Can't cope with incremental changes
    • Compliance costs can rise
    • often only publish lowest common denominator requirements
    • Make decisions on your behalf out of context
    • Can never make exhaustive analysis and comparison of alternatives
  • Testing and revision processes
    • It is not easy to develop or test new solutions identified during the construction phase
    • It is difficult to respond to new needs or requirements

The Habitat aims to exceed modern standards by orders of magnitude, yet may be handicapped by being unable to apply modern project management principals practices such as;

  • Agility
  • Set Based Design we will refer to as "Distributed component design" (to be reviewed)
