But, yes, most houses around me have so many flaws that it seems problematic to count them as assets. Christopher Alexander has a lengthy calculation on this in 'The Nature of Order.'
They don't have to be identical copies at all, in the computer age.
I live in a newish housing estate in a relatively affluent area of the UK, where every single house has the same cladding, the same colour of roof, the same colour of doors, the same colour and style of windows, the same small patch of grass out the front, and each house is separated by less than 2m.
Walking around the place feels... wrong, hollow, eerie somehow. And yet, many people seem to love this homogeneous kind of place.
Thing is, as you point out, it doesn't have to be this way - it's local planning regulations and NIMBY neighbours that are the problem. Why does every house need to look almost identical? Why do I need permission to paint my front door a different colour?
It's not prefabrication that prevents diversity - it's policy.
Also, the vast majority of the cost of a half million dollar home is the land.
But it doesn't conform to regulations and/or everyone that has a veto in the planning and permit process.
There is no technology that fixes people problems. I would say Skynet from Terminator was onto something but still failed :)
I'm looking to design my own home and very much agree with what you have to say. I'd be interested in hearing more of your thoughts.
Compared to building the same stuff in a factory, it is.
TL;DR: Buildings and neighborhoods should be designed in situ by the people living there.
The PL volumes are earlier and seminal (both SimCity and the concept of "Patterns" in programming are two examples) while the more mature Nature of Order is nearly mystic.
I'm convinced that if we could combine the ideas of Pattern Language with applied ecology we could create a new form of civilization so beautiful our ancestors would consider it Heaven on Earth.
I'm currently writing a series on designing my own home and contrasting it with some soul-crushing new construction around here. It's very obvious that the places cherished and loved in New Hampshire were the villages built slowly, and the places least loved are the ones flash formed overnight by contractors trying to max out $$. Building on site is not very expensive but I'm not sure that making it cheaper is fixing any of the major problems with housing. It would just give more life to planning for lifeless sprawl.
If anything, we need ways to build more beautiful houses better or cheaper, in smaller, odd and non-level lots. Not assembly line houses.
